ELECTRIC APPLICATOR AND METHOD FOR RE-AFFIXING ARTIFICIAL LASH EXTENSIONS AND CURLING NATURAL LASHES AND ARTIFICIAL LASH EXTENSIONS ATTACHED TO NATURAL LASHES

FIELD OF THE INVENTION

[0001] Embodiments of the disclosure relate generally to applicators for natural lashes and artificial lash extensions and, more specifically, to electric applicators for re-affixing artificial lash extensions and curling natural lashes and/or artificial lash extensions attached to natural lashes.

BACKGROUND

[0002] False eyelash extensions have conventionally been used to enhance the length, thickness, and fullness of natural eyelashes. Some false eyelashes may be applied directly to an individual’s eyelid. False eyelashes can come in strips (and thus may also be referred to as “strip lashes”) that can be trimmed to fit the width of the individual’s eyelid.

DETAILED DESCRIPTION

[0057] As noted above, eyelash extensions have been used to enhance the length, thickness, and fullness of natural eyelashes. Strip lashes applied to a user’s eyelids are easily distinguishable from a user’s natural lashes and can be unconformable if worn for long periods of time. Some eyelash extensions are applied to an individual’s natural lashes hair by hair or in some cases cluster by cluster. Due to the precise nature of applying single hairs or clusters, skilled technicians can perform the application of said single hairs or clusters. Such services can cost hundreds of dollars and take up to several hours to complete.

[0058] In some cases, an individual may desire to curl the individual’s natural lashes and/or the eyelash extensions that have been applied to the individual’s natural lashes. Due to the unique geometry and sensitivity of the eye area, existing tools may not use heat to curl the natural lashes and/or artificial lash extensions or have a shape or other features that are ill- suited to curl the natural lashes and/or eyelash extensions.

[0059] In still other cases, the eyelash extensions that are worn by an individual may fall off or otherwise have reduced bond to the individual’s natural lashes. The individual may desire to improve the bond quality and increase the amount of time the eyelash extensions can be worn by the individual.

[0060] To address the above-mentioned and other challenges an electric applicator is disclosed herein that is designed to curl one or more of the natural lashes or artificial lash extensions attached to the natural lashes. The electric applicator provides a new and improved way of curling the lashes, artificial lash extensions, or both with much more control than conventional solutions. The electric applicator can also be used to re-affix artificial lash extensions that have been previously attached to the natural lashes (e.g., days before) so that the bond between the natural lashes and artificial lash extension is improved and extended over time.

[0061] In some embodiments, the electric applicator includes a handle and a pair of opposing arms coupled to the handle. Each arm includes a section that has a first curvature between a first end portion and a second end portion of the section. The first curvature is shaped to align proximate the lash line of the eye area. The electric applicator includes a heating unit that is configured to heat the section of each arm (e.g., both the interior surface and exterior surface of the section).

[0062] In some embodiments, the electric applicator includes a cooling unit to cool the section of each arm.

[0063] In some embodiments, at least part of the interior surface corresponding to the first section of each arm includes a surface that is substantially flat and designed to apply pressure to the natural lashes and one or more artificial lash extensions attached to (e.g., an underside of) the natural lashes. In some embodiments, at least part of the exterior surface corresponding to the first section includes a curved portion with a surface having a curvature positioned between the first side and the second side of each arm. The curvature of the curved portion of the first section (along with heat) is designed to curl one or more of natural lashes or one or more artificial lash extensions attached to the natural lashes.

[0064] In an illustrative embodiment to curl the natural lashes and artificial lash extensions, the electric applicator can be heated to a desired temperature. The heated electric applicator can be closed on the natural lashes and artificial lash extensions attached thereon such that the heated interior surfaces of the arms of the heated electric applicator contact and apply pressure to the natural lashes and artificial lash extensions therebetween. The heated electric applicator can be rotated about a rotational axis and the natural lashes and/or artificial lash extensions can contact the heated exterior surface (that can also be curved) of the section of at least one arm. Contact between the natural lashes and/or artificial lash extensions and the interior surfaces and exterior surface(s) of the arm(s) of the heated electric applicator can be maintained for a time period to set the curl of the natural lashes and/or artificial lash extensions.

[0065] In another illustrative embodiment to re-affix artificial lash extensions attached to that natural lashes using an adhesive, the electric applicator can be heated to a desired temperature. The original attachment of the artificial lash extensions may have occurred at some time period prior, such as days prior to the re-affixing. The heated electric applicator can be closed on the natural lashes and artificial lash extensions attached thereon such that the heated interior surfaces of the arms of the heated electric applicator contact and apply pressure to the natural lashes and artificial lash extensions therebetween. The originally applied adhesive can begin to soften and be redistributed among the natural lashes and the adjacent artificial lash extensions. After a time period, the heated electric applicator can be removed and the cooling unit of the electric applicator activated. The pair of opposing arms can cool to a desired temperature and be closed on the natural lashes, artificial lash extensions, and redistributed adhesive. The redistributive adhesive can harden and recreate and improve the bond between the natural lashes and artificial lash extensions such that the time period during which the artificial lash extensions can be worn is extended.

[0066] FIG. 1 is an illustration of an eye area, in accordance with some embodiments of the disclosure. As shown in FIG. 1, the eye area 100, such as a human eye area, can include upper natural lashes 102A (also referred to as “natural lashes 102A,” “natural eyelashes 102A,” or “natural lash 102A” herein) and lower natural lashes 102B (also referred to as “natural lashes 102B,” “natural eyelashes 102B,” or “natural lash 102B” herein). Natural lashes 102 A and 102B can have an underside and topside opposite the underside. For example, natural lashes 102 A illustrate an underside 108. Natural lashes 102B illustrate a topside 110. Natural lashes 102A and 102B are collectively referred to as natural lashes 102, herein.

[0067] The eye area 100 includes an upper lash line 104 (also referred to as “lash line 104” herein) and upper waterline 106 (also referred to as “waterline 106” herein). In some embodiments, a lash line, such as the upper lash line 104 or lower lash line of natural lashes 102B, can include the area between the natural lashes. In some embodiments, the lash line can be curved and follow the alignment of the natural lashes 102. In some embodiments, the upper lash line 104 can include some area of the skin that is above (e.g., directly above) the natural lashes 102A and/or below (e.g., directly below) the natural lashes 102A. Similarly, the lower lash line can include some area of the skin that is below (e.g., directly below) the natural lashes 102B and/or above (e.g., directly above) the natural lashes 102B.

[0068] In some embodiments, the waterline (also referred to as “wetline” herein), such as upper water line 106 corresponding to natural lashes 102 A and lower water line corresponding to natural lashes 102B, can include an area (or line) of skin that is exposed between the natural lashes 102 and the eye.

[0069] Spatially relative terms, such as “under,” “upper,” “lower,” “top,” “bottom,” and so forth as used herein refer to a relative position of one element with respect to another element. Unless otherwise specified, the spatially relative terms are not intended to be limiting to the absolute orientation, and are intended to encompass different orientations (e.g., rotated 90 degrees, flipped, etc.) of elements in addition to the orientation depicted in the Figures. For example, if elements in the Figures are rotated 180 degrees, elements described as “upper” elements can then be considered oriented as “lower” elements, without deviating from aspects of the disclosure.

[0070] FIG. 2 is an illustration of an exemplary artificial lash extension, in accordance with some embodiments of the disclosure. FIG. 3 is an illustration of another exemplary artificial lash extension, in accordance with some embodiments of the disclosure.

[0071] In some embodiments, one or more of artificial lash extension 200 or artificial lash extension 300 (both also referred to as “lash extension” or “artificial eyelash extension” herein) are designed or configured for application at the natural lashes, such as at the underside of the natural lashes of a user or even the topside of the natural lashes of a user. In some embodiments, one or more of artificial lash extension 200 or artificial lash extension 300 can be part of a set of multiple artificial lash extensions. In some embodiments, one or more of artificial lash extension 200 or artificial lash extension 300 can be a segment of a “full” artificial lash extension such that, for instance, when multiple artificial lash extensions are arranged adjacent to one another at the underside of natural lashes (e.g., natural lashes 102 A) the arranged artificial lash extensions span the length of the natural lashes. In some embodiments, the artificial lash extensions (e.g., segments) can be shorter than the horizontal length of the natural lashes (e.g., length of the lash line). In other embodiments, an artificial lash extension can be longer such that the artificial lash extension is a “full” artificial lash extension that substantially spans the horizontal length of the natural lashes. The artificial lash extensions can be arranged to substantially align with the lash line of the user. In some embodiments, using artificial lash extensions that are independent segments can allow an individual artificial lash extension to move independently when bonded to the underside of natural lashes, which mimics the movement of the natural lashes and can improve the feel, comfort, and longevity of the artificial lash extensions.

[0072] Artificial lash extension 200 and artificial lash extension 300 respectively depict artificial hairs 202A-202N (collectively referred to as “artificial hairs 202” herein) and artificial hairs 302A-302N (collectively referred to as “artificial hairs 302” herein). In some embodiments, the artificial hairs of an artificial lash extension, such as artificial lash extension 200 or artificial lash extension 300, can be formed from one or more synthetic materials, including but not limited to polybutylene terephthalate (PBT), acrylic resin, polyester (e.g., polyethylene terephthalate (PET)), other polymers, other synthetic material, or a combination thereof. In alternative embodiments, a natural material such as natural hair (e.g., human hair or mink hair) can be used. In some embodiments, the artificial hairs of a particular artificial lash extension can have one or more lengths and/or one or more diameters. In some embodiments, the diameter of an artificial hair can be between approximately 0.0075 millimeters (mm) (e.g., 0.0075mm +/- 0.0025mm) to 0.3 mm (e.g., 0.3 mm +/- 0.05mm). In some embodiments, the ends of one or more of the artificial hairs can be tapered. In some embodiments, the one or more of the artificial hairs can be curled or shaped in particular direction. For example, the ends 208 of artificial hairs 202 or the ends 308 of artificial hairs 302 can be tapered or curled or both. In some embodiments, the artificial hairs can range from 3 mm to 30 mm in length or in some instances even longer.

[0073] In some embodiments, an artificial lash extension can include a base. For example, artificial lash extension 200 includes base 206. In some embodiments, artificial lash extension 300 may or may not (as illustrated) include a base similar to base 206 of artificial lash extension 200. The base can include a top side (e.g., facing out of the page and towards the reader), a bottom side, a back side, a front side, and two lateral sides. In some embodiments, one or more of the multiple artificial hairs of an artificial lash extension protrude out the front side of the base. When arranged at the underside of natural lashes, the backside of the artificial lash extension can point towards the user’s eye. The thickness (e.g., between the topside and bottom side of the base) can be between approximately 0.05 millimeters (mm) and approximately 0.15mm (e.g., 0.05mm +/- 0.01mm). In some embodiments, the thickness of the base can be less than 0.05 mm. In some embodiments, the low profile of the base is designed to allow the artificial lash extension to be light weight so as to better adhere to the underside of the natural lashes and in some instances to prevent obstruction of a user’s view. The low profile of the base can at least in part be attributed to an application of heat in the formation of the base.

[0074] In some embodiments, one or more of the top side or bottom side (e.g., surface) of the base is substantially flat (e.g., having a flatness control tolerance value of +/- 0.03mm or +/- 0.015 mm). In some embodiments, the flatness of the base of the artificial lash extension 200 is designed to allow improved contact and adhesion to a surface, such as the underside of natural lashes or the opposing surface of another artificial lash extension. The flatness of the base can at least in part be attributed to an application of heat in the formation of the base. [0075] In some embodiments, the base can be formed at least in part by an application of heat at or near the area of the base. The application of heat can cause one or more of the artificial hairs (e.g. all of the artificial hairs or clusters) of an artificial lash extension to be connected to or at the base. In some embodiments, a heated fixture, such as a heated platen, a heated crimp, heating lamp, heating oven, or other device can be used (e.g., pressed against the artificial hairs) to cause the artificial hairs (e.g., artificial hairs of one or more clusters) to at least become soft, tacky or sticky (e.g., at least partially melt). In some embodiments, the at least partially melted artificial hairs (e.g., of one or more clusters) form at least part of the base. In some embodiments, the application of heat at least partially melts the artificial hairs such that the multiple artificial hairs connect to or at the base of the artificial lash extension. In some embodiments, the application of heat at least partially melts the artificial hairs such that at least some of the multiple artificial hairs connect to each other at the base of the artificial lash extension.

[0076] In some embodiments, to at least partially melt the artificial hairs (e.g. and/or artificial hairs of a cluster) at the base the artificial hairs can be heated to a temperature between 55-100 degrees Celsius, which can cause the artificial hairs to be connected to or at the base and/or in some cases to each other. In some embodiments, the application of heat is at a temperature above, within or at the glass transition temperature of the material of the artificial hairs. At the glass transition temperature the material of the artificial hairs transitions from brittle to a softer, rubbery, tacky or pliable state. In some embodiments, the application of heat is at a temperature above, within or at the melt temperature of the material of the artificial hairs. For example, the base area (and/or other parts of the artificial lash extension) can be heated above 200 degrees Celsius.

[0077] In some embodiments, one or more additional artificial materials, such as one or more artificial hairs or other material(s) can be placed substantially orthogonal to the artificial hairs (e.g., generally aligned horizontal with respect to the lengthwise direction of the artificial hairs). In some embodiments, the additional artificial material can be connected to the artificial hairs. In some embodiments, the additional artificial material can be considered a base or at least an initial base. In some embodiments, the additional artificial material can be considered at least part of the base that is to be formed. In some embodiments, heat can be applied to the area where the base is to be formed (which can include the additional artificial material). In some embodiments, one or more of the artificial hairs and/or the additional artificial material can at least partially melt to at least in part, form the base. In some embodiments, the additional artificial material can include an adhesive (e.g. application of adhesive) that is used alone or with one or more other artificial material(s) (e.g., horizontal artificial hair, nylon, etc.). In some embodiments, the application of heat can be used to help cure the applied adhesive. In some embodiments that use an adhesive, the application of heat may or may not partially melt the artificial hairs.

[0078] In some embodiments, the base can at least in part be formed by an application of pressure. In some embodiments, the base can be formed by an application of pressure combined with an application of heat. For example, an application of pressure along with an application heat can be concurrently applied at the base of the artificial lash extension to cause at least some of the artificial hairs (e.g., some of the artificial hairs of a cluster) to at least partially melt and connect together (e.g., secured together) and/or connect to (e.g., secured to) an additional artificial material.

[0079] In some embodiments, prior to the application of heat the artificial hairs may be tied (e.g., knotted) to a support or base thread or fiber to align the artificial hairs and prevent the horizontal spreading of the artificial hairs. Heat can be applied as described above (while the artificial hairs are knotted to a support thread) such that the support thread forms part of the base. In other instances, heat can be applied below the horizontal support thread. For instance, the support thread can hold the artificial hairs in place and the application of heat can form a base below the support thread. In other embodiments, the artificial hairs are not aligned with a support thread (e.g., are not knotted on a support thread) before or during the formation of the base using the application of heat.

[0080] In other embodiments, the artificial hairs can be arranged using a stencil or other arrangement device before and/or during the formation of the base using the application of heat. In some embodiments, one or more applications of heat can be performed to form the base. In an alternative embodiment, the base can be formed in part or in full using a chemical process.

[0081] In some embodiments, one or more of artificial lash extension 200 and artificial lash extension 300 include artificial hairs 202 and 302 that are respectively configured into clusters of artificial hairs 204A-204G (collectively referred to as “clusters 204” herein) and clusters of artificial hairs 304A-304G (collectively referred to as “clusters 304” herein). In some embodiments, a cluster of artificial hairs can refer to two or more artificial hairs that are grouped together. In some embodiments, two or more artificial hairs of a cluster can contact one another before and/or after an application of heat. In some embodiments, 2-30 artificial hairs can be included in a cluster.

[0082] In some embodiments, the clusters of artificial hairs can be connected to or at the base with an application of heat in a similar manner as described above. In some embodiments, the application of heat can at least partially melt at least some of the artificial hairs in one or more clusters of the artificial lash extension. In some embodiments, the application of heat can at least partially melt at least some of the artificial hairs of at least one cluster so that at least some of the artificial hairs of the cluster connect to one other. In some embodiments, the application of heat can at least partially melt at least some of the artificial hairs of at least one cluster so that at least some of the artificial hairs of the cluster connect to the base of the artificial lash extension (and/or form, at least in part, the base of the artificial lash extension). In some embodiments, at least some of the artificial hairs of at least one clusters are connected to one another at a respective part of the base by at least the application of heat.

[0083] In some embodiments, the clusters are connected to one another at the base by the application of heat. In some embodiments, one or more of the clusters of the artificial lash extension are directly connected to at least one adjacent cluster at the base. In some embodiments, one or more of the clusters of the artificial lash extension are indirectly connected to at least one adjacent cluster of the artificial lash extension at the base.

[0084] In some embodiments, at least two artificial hairs of an artificial lash extension crisscross each other. For example, two artificial hairs of a particular cluster can crisscross one another. In some embodiments, one or more individual clusters of artificial hairs can be formed using an application of heat as described above. Thus, the clusters can have a base (e.g., cluster base). The clusters can be arranged and heat can be applied, as described above, to the cluster bases to form at least in part the base (e.g., base 206) of the artificial lash extension.

[0085] In some embodiments, artificial lash extensions 200 or 300 may be 4-10 mm wide. In some embodiments, artificial lash extension 200 or 300 may be 5-6 mm wide. In some embodiments, the width of an artificial lash extension is much wider than a single cluster that is typically 1 -2 mm wide.

[0086] Artificial lash extension 300 further illustrates adjacent artificial hairs (or adjacent clusters 304) that are coupled or secured to one another at connecting portions 310A-310H (collectively referred to as “connecting portions 310” herein) of the crisscrossing artificial hairs 302. For example, at least one hair of particular cluster can be secured (e.g., directly or indirectly) to one or more hairs of an adjacent cluster at a connecting portion. In some embodiments, connecting portions can connect artificial hairs (e.g., clusters) of an artificial lash extension together at areas between the two ends of the artificial hairs such that the artificial hairs of the of the artificial lash extension are connected directly or indirectly to one another to form an artificial lash extension and both ends of the artificial hairs not connected together (e.g., open ended).

[0087] In some embodiments, the connecting portions 310 can be considered a base, as described herein. In some embodiments, the connecting portions can be formed by an application of heat in a similar manner as described herein. In some embodiments, the connecting portions can be formed by an application of pressure in a similar manner as described herein. In some embodiments, the connecting portions 310 can be formed using one or more of an application of heat, an application of adhesive, an application of pressure, or a chemical process as described herein. For example, the crisscrossing artificial hairs 302 are connected or secured together approximately 1mm to approximately 5 mm (+/- 0.5 mm) above the ends 306 of the artificial hairs 302 (e.g. the ends 306 that are opposite the ends 308).

In some embodiments, the operations as described below with respect to FIGS. 6B through 6F are performed during a second application session. The second application session (re-affixing) can be performed after some time period (e.g., hours or days) after the performance of the first application session. In some embodiments, the re-affixing operation(s) of the second session can be performed to re-bond or enhance the bond between the artificial lash extensions and the natural lashes.

[0137] FIG. 6B illustrates the positioning of the electric applicator in an aligned orientation, in accordance with some embodiments of the disclosure. FIG. 6B shows the heated electric applicator 400 positioned in an aligned orientation at the eye area. In the aligned orientation, the curvature 428 of each arm 402 is aligned with the lash line of the natural lashes. In some embodiments and not shown in FIG. 6B, the electric applicator 400 is obtained and activated such that the heating unit of the electric applicator 400 is activated to heat the section 410 of each arm 402 to the desired temperature. The electric applicator 400 is also shown in the open position.

[0138] FIG. 6C illustrates transitioning the electric applicator to a closed position, in accordance with some embodiments of the disclosure. FIG. 6C shows the heated electric applicator 400 transitioned from the open position (e.g., shown in FIG. 6B) to a closed position by closing the section 410 of the pair of opposing arms 402 onto the natural lashes and artificial lash extensions 500 therebetween. In some embodiments, an in particular to re- affix the artificial lash extensions 500, the heated electric applicator 400 can be positioned towards or closer to the lash line the natural lashes or base of the artificial lash extensions 500 (e.g., away from the ends of the artificial lash extensions). The heated electric applicator 400 in the closed position is shown in the aligned orientation.

[0139] In some embodiments, to perform the re-affixing operation(s) the heated electric applicator 400 is maintained in the closed position (and in the aligned orientation or another orientation) for a time period (e.g., 5-300 seconds) to soften the adhesive used to attach (e.g., arrange and/or affix) the artificial lash extensions 500 to the natural lashes. In some embodiments, the adhesive can be the original adhesive (e.g., see FIG. 5A) used to arrange and affix the artificial lash extensions during the initial application session. In some embodiments, additional adhesive can be applied. In some embodiments, no additional adhesive is applied (e.g., additional to the initial application session). For example, the adhesive that bonds the artificial lash extensions to the natural lashes can be several days old and have hardened over that time period. The introduction of heat to the hardened adhesive can cause the adhesive to soften and reflow or redistribute the adhesive to different contact areas between the artificial lash extensions and natural lashes.

[0140] FIG. 6D illustrates artificial lash extensions after the heated electric applicator has been removed, in accordance with some embodiments of the disclosure. FIG. 6D shows the artificial lash extensions after the removal of the heated electric applicator 400 from the eye area. The adhesive has been heated and can still be sticky or tacky. In some embodiments, the cooling unit 450 of the electric applicator 400 can be activated to cool section 410 of each arm 402 of the electric applicator 400.

[0141] FIG. 6E illustrates the cooled electric applicator positioned in the aligned orientation and in the closed position, in accordance with some embodiments of the disclosure. In some embodiments, the cooled electric applicator 400 can be positioned in an aligned orientation at the eye area in the open position (not shown, but similar to FIG. 6B). In the aligned orientation, the curvature 428 of each arm 402 is aligned with the lash line of the natural lashes. In some embodiments, the cooling unit 450 of the electric applicator 400 is activated to cool the section 410 of each arm 402 to the desired temperature.

[0142] In some embodiments, the cooled electric applicator 400 is transitioned from the open position (e.g., similar to FIG. 6B) to a closed position by closing the section 410 of the pair of opposing arms 402 on the natural lashes and artificial lash extensions 500 that are attached (e.g., affixed) to the natural lashes. In some embodiments, an in particular to re-affix the artificial lash extensions 500, the cooled electric applicator 400 can be positioned towards or closer to the lash line of the natural lashes or base of the artificial lash extensions 500 (e.g., away from the ends of the artificial lash extensions). The cooled electric applicator 400 in the closed position is shown in the aligned orientation (but can be in a different orientation in some embodiments).

[0143] In some embodiments, to perform the re-affixing operation(s) the cooled electric applicator 400 is maintained in the closed position (and in the aligned orientation or another orientation) for a time period (e.g., 5-180 seconds) to harden the adhesive used to affix the artificial lash extensions 500 to the natural lashes. In some embodiments, the time between heating the adhesive and cooling the heated adhesive can be less than 5 minutes or at least during the same application session. By cooling the adhesive, the adhesive hardens to recreate and even improve the bond between the artificial lash extensions and the natural lashes.

[0144] FIG. 6F illustrates artificial lash extensions after the cooled electric applicator has been removed, in accordance with some embodiments of the disclosure. FIG. 6F shows the artificial lash extensions after the removal of the cooled electric applicator 400 from the eye area. The adhesive has been heated and subsequently cooled. Although electric applicator 400 has been used to illustrate the cooling of the adhesive, in some embodiments a different applicator can be used. For example, a purely mechanical applicator (e.g., metal applicator) can be put in the freezer and subsequently be used to perform the cooling, as described herein.

[0145] Method 700 is described as a series of operations (or acts). It should be understood that some operations can be performed concurrently with other operations. In some embodiments, the same, fewer or greater number of operations can be performed in the same or different order. In some embodiments, different operations can be performed or the multiple operations can be combined into a single operation, or a single operation can be performed using multiple operations.

[0146] FIGS. 7A-7C are flow diagrams illustrating operations for affixing artificial lash extension, curling artificial lash extensions and re-affixing artificial lash extensions, in accordance with embodiments of the disclosure. Method 700 of FIGS. 7A-7C can be performed by a user. In some embodiments, the user can use an electric applicator 400, as described herein, or different applicator to perform at least some of the operations of method 700. The user of method 700 can be the same user on whom the artificial lash extensions are applied or another user that applies the artificial lash extensions on behalf of the user.

[0147] At operation 705 of method 700, an adhesive may be applied to natural lashes of a user. In some embodiments, the adhesive can be applied to the underside of the natural lashes, such as the underside of the upper natural lashes. In some embodiments, rather than the underside, the adhesive may be applied to the top or sides of the upper natural lashes.

[0148] In some embodiments, the adhesive may be one or more of a glue, a mascara, a bonding agent, an epoxy, a paste, or any other natural or synthetic substance having an adhesive quality. In some embodiments, the adhesive may be a waterproof formulation that allows artificial lash extensions (and/or detached artificial hairs thereof) to remain affixed to the individual’s natural lashes for periods of time (e.g., hours, days, weeks, or months). In some embodiments, the adhesive may be a commercially-available adhesive for conventional lash extensions or a specialized composition for use with the lash extensions described herein. The adhesive may be clear or colored (e.g., milky white or black to emulate mascara). [0149] In some embodiments, the adhesive may be applied using a brush, a comb, or any other type of application tool. In some embodiments, the adhesive may be applied one to two millimeters away from the waterline. In other embodiments, the adhesive may be applied at any location along the natural lashes or along the waterline. In some embodiments, it may be desirable to wait a predetermined period of time prior to proceeding to operation 710 to allow for the adhesive to activate (e.g., partially cure or dry) its adhesive quality.

[0150] At operation 710, the user arranges one or more artificial lash extensions at the natural lashes of the user. In some embodiments, the one or more artificial lash extensions may be arranged at the underside of the natural lashes. In some embodiments, the top side of each base of each of the artificial lash extensions can be arranged directly to the underside of the natural lashes (rather than to the eyelid). In some embodiments, the one or more artificial lash extensions may be arranged to align with the curvature of the lash line. For example, multiple artificial lash extensions may be arranged adjacent to one another (e.g., not overlapping or overlapping) such that the bases align with the curvature of the lash line.

Thus, the one or more artificial lash extensions may become substantially flush with the lash line when the artificial lash extensions are arranged proximate to the lash line.

[0151] In some embodiments, one or more artificial lash extensions can be arranged at the underside of the natural lash at a time. For example, a single artificial lash extension can be arranged first, another artificial lash extension can be arranged subsequently, and so forth. In some embodiments, an applicator, such as electric applicator 400, can be used to arrange the one or more artificial lash extensions. The user can further re-arrange one or more of the artificial lash extensions as desired.

[0152] In some embodiments, arranging the one or more artificial lash extensions at the natural lashes of the user includes arranging the one or more artificial lash extensions adjacent to one another at the natural lashes.

[0153] In some embodiments, the artificial lash extensions arranged at the natural lashes can include one to eight distinct artificial lash extensions. The number of artificial lash extensions arranged at the natural lashes may be based on the width of the artificial lash extension, the thickness of the artificial hair used, the desired style, the desired lash density (also referred to as “fullness” of the user’s lashes), etc.

[0154] In some embodiments, rather than applying adhesive to the natural lashes (as discussed at operation 705) and then arranging the one or more artificial lash extensions to the natural lash (as discussed at operation 710), the adhesive may be applied to (e.g., the topside of) one or more artificial lash extensions, and then the artificial lash extensions may be arranged at (e.g., the underside of) the natural lash.

[0155] At operation 715, the user can affix the artificial lash extensions to the natural lashes. In some embodiments, each of the artificial lash extensions may be affixed (e.g., bonded) to the underside of the natural lashes. In some embodiments, once the one or more artificial lash extensions are arranged in a desired arrangement, the artificial lash extensions are secured to and more permanently attached (e.g. for days) to a surface, such as the underside of the natural lashes. In some embodiments, one or more of an application of pressure using the electric applicator 400, as described herein, or different applicator or passage of time to cure the adhesive can be used to help affix the detached artificial hairs. [0156] In some embodiments, operations 705 through 715 are performed during a first application session. In some embodiments one or more of operations 720 through 775 are performed during a second application session. In some embodiments, the second application session is performed a time period after the first application session. The time period can be greater than 6 hours or greater than 1 day, for example. In some embodiments, one or more of operations 705 through 775 can be performed during the same application session.

[0157] At operation 720, the electric applicator 400 is obtained. In some embodiments, the electric applicator 400 includes a pair of opposing arms and a heating unit. Each arm includes a first section (e.g., section 410) having a first curvature (e.g., curvature 428) disposed between a first end portion (e.g., end portion 424) and a second end portion (e.g., end portion 426) of the first section.

[0158] In some embodiments, each arm further includes a first side (e.g., side 412) opposite a second side (e.g., side 414), and an interior surface (e.g., interior surface 418) opposite an exterior surface (e.g., exterior surface 416). The interior surface and the exterior surface extend between the first side and the second side.

[0159] In some embodiments, the first section of each arm includes a second curvature (e.g., curvature 434) disposed between the first end portion and the second end portion and along at least a part of the first side corresponding to the first section. In some embodiments, the second curvature is positioned opposite the first curvature. In some embodiments, the first curvature is disposed along at least a part of the second side corresponding to the first section. In some embodiments, first curvature is a concave curvature and the second curvature is a convex curvature.

[0160] In some embodiments, at least part of the interior surface corresponding to the first section includes a surface that is substantially flat. In some embodiments, at least part of the interior surfaces corresponding to the first sections of the opposing arms are designed to apply pressure to natural lashes and the artificial lash extensions attached to the natural lashes.

[0161] In some embodiments, at least part of the exterior surface corresponding to the first section includes a surface having a third curvature (e.g., curvature 430) extending between the first side and the second side. In some embodiments, at least part of the exterior surface corresponding to the first section is designed to curl one or more of the natural lashes or the artificial lash extensions attached to the natural lashes.

[0162] At operation 725, the user activates the heating unit of the electric applicator. Activating the heating unit may heat the first sections of each arm to the desired temperature, in some embodiments.

[0163] At operation 730, the heated electric applicator is positioned in an aligned orientation at an eye area of a user. In some embodiments, in the aligned orientation the first curvature of each arm is positioned to align with a lash line of the natural lashes. In some embodiments, the heated electric applicator is positioned in the aligned orientation while in the open position.

[0164] At operation 735, the heated electric applicator is transitioned to a closed position. In some embodiments, the heated electric applicator is transitioned to the closed position by closing the first sections of the pair of opposing arms on the natural lashes and artificial lash extensions attached to the natural lashes. In some embodiments, if proceeding to branch A (e.g., curling the natural lashes and/or artificial lash extensions) the first sections of the heated electric applicator can closed on the natural lashes and/or artificial lash extensions near the ends of the natural lashes and/or artificial lash extensions. In some embodiments, if proceeding to branch B (e.g., re-affixing the artificial lash extensions) the first sections of the heated applicator can close on the natural lashes and/or artificial lash extensions near the lash line or base, respectively.

[0165] In FIG. 7B at operation 740 of branch A, the heated electric applicator in the closed position is rotated to a rotated orientation. In some embodiments, a user rotates the heated electric applicator in the closed position along a rotational axis to transition the heated electric applicator from the aligned orientation to a rotated orientation. In some embodiments, in the rotated orientation one or more of at least part of the natural lashes or at least part of the artificial lash extensions contact an exterior surface of the first section of at least one of the pair of opposing arms of the heated electric applicator.

[0166] At operation 745 of branch A, the heated electric applicator is maintained in the closed position and the rotated orientation for a time period to curl one or more of the natural lashes or the artificial lash extensions.

[0167] In FIG. 7C at operation 750 of branch B, the heated electric applicator is maintained in the closed position for a time period. In some embodiments, the heated electric applicator is maintained in the closed position for a time period to soften an adhesive used to attach the artificial lash extensions to the natural lashes.

[0168] At operation 755 of branch B, the heated electric applicator is removed from the eye area.

[0169] At operation 760 of branch B, the cooling unit of the electric applicator is activated. In some embodiments, activating the cooling unit cools at least the first section of each arm.

[0170] At operation 765 of branch B, the cooled electric applicator is positioned at the eye area of the user. In some embodiments, the cooled electric applicator is positioned in the aligned orientation while in the open position.

[0171] At operation 770 of branch B, the cooled electric applicator is transitioned to the closed position.

[0172] At operation 775 of branch B, the cooled electric applicator is maintained in the closed position for a time period. Maintaining the cooled electric applicator in the closed position can harden the adhesive used to attach the artificial lash extensions to the natural lashes.
