State of art After the appearance of the grey hair there exist two possibilities. Either to leave it in its natural greyness or to deposit in different ways some dye on the entire hair, i. e. to dye the entire hair. The desire to give some other colour to one or to several hair tufts is solved in the following ways: On the head of the person with the mentioned desire a rubber cap with multiple srnall openings is slipped on. With the steel hook the tufts are pulled out through the openings, which are then dyed by means of one of the procedures. The paintbrush or small spade takes the dye, and by sliding along the brush or spade and by tapping on the tuft the dye is deposited on the hair. After that, another rubber cap preventing the dye drying is slipped on.

The other way is that the individual tuft is manually separated stretched and kept in the air separated from the rest of the hair, or to put an aluminium foil underneath. Then, the dye is deposited by means of the paintbrush or the small spade, the tuft is wrapped up into the aluminium foil that protects the remaining hair to remain undyed and prevents the quick dye drying, what could interrupt the hair dyeing process.

The first way can be painful, while the other one requires skill and experience, and there exists a risk either that the dye falls on the remaining hair or that the dye leaks through the aluminium foil.

The hair dying in one's own realisation is performed in a way that two or more chemical ingredients packed in separate vessels are mixed by manual mixing or by shaking. The mixture obtained in such a way is manually spread all over the hair. The part of the mixture that is not used must be thrown away at once.

Exposure of the invention essence The primary goal of the invention is: 1) To enable to the persons having only a limited number of grey hair to dye only the individual, grey hair without depositing chemicals on the hair that has retained the natural colour.

2) To enable the dyeing of the hair tufts by depositing the dye by a simple dragging- through of the pincers with a sponge rubber soaked with dye, by which the desired tuft is embraced.

3) To enable the hair dyeing to the hair root, what is possible by using the extension for the precise dyeing.

4) The increase of the working speed when dyeing the hair tufts by using the dyed tuft protection with the latex hose.

5) By increasing the work speed the hair dyeing costs are reduced, and its simple use enables also the one's own tuft dyeing at home.

The secondary goal of the invention is: 1) A simple and quick application in a way that everybody can dye only the individual grey hairs by himself, at home and without losing time.

2) A very simplified tuft dyeing, what enables to persons, who are not especially educated and trained, to dye by themselves, at their home, one or more tufts.

The further goal of the invention is the saving of the dye-stuff, because only the quantity for the individual dyeing is mixed, while the rest of the non-used and non-mixed stuff remains conserved and enables a multiple use. Thus, the throwing- away of the prepared but not used stuff is avoided, what contributes, beside to the stuff saving, also to the environment ecology. This saving brings the reduction of the dyeing costs.

The next goal is the simple use, easy dosing and mixing, so that the packing in several separate containers, which contents is necessary to be mixed manually, is avoided.

The set for the precise dyeing of individual hairs and for the hair tuft dyeing in all versions (except the version for the single use) comprises: the body inside of which there are one or more containers for the dye-stuff or its components, on the front end openings for the dye pressing-out are made which are decentred from the body axis in a way that by turning the top carrier for about 45 degrees they open or close ; the pistons for pressing out the container contents; system for pushing the pistons, rear part or the cover that closes the body, the top carrier by which turning about the axis the openings for the dye pressing-out are opened and closed, and in the same top carrier the spiral for the dye components that are pressed through it and the chosen top are placed, and on the top carrier the pincers for the hair tuft dyeing can be placed.

Detailed description of the invention realisation Version A Injector for hair dyeing with the use of the two-component dye-stuff that is pressed 130 out by turning the little wheel with the top for the precise dyeing.

In injector body (6) there are the containers with the hair dyeing ingredients: the developer and the dye-stuff. The container volumes can be different, depending on the applied ingredient-mixing ratio. The usual preparations are mixed in the ratio from 1: 3 to 1: 1. The exact ratio of the ingredients is regulated by the size of the 135 opening section through which the ingredients are pressed out of the container and by the area of pistons (7) and (8).

On the rear part there is small wheel (11) with the screw. By turning small wheel (11) also screw (11A), as its part, turns. By turning screw (11A), nut (12) wound on screw (11A) of small wheel (11) with the screw moves linearly, because it 140 is made in such a way that a sector is missing and by that even part it leans against the inner wall of body rear part (9), which one inner wall is even and by that the turning of nut (12) is prevented and its linear motion is secured. Nut (12) by the linear motion pushes axles (15) that push pistons (7) and (8). The pistons uniformly press out the ingredients from the containers and the ratio is determined by the diameter of 145 openings (19) and (20) through which they are pressed out and by the diameter of the container, i. e. by the diameter of smaller piston (7) and bigger piston (8), i. e. by their interrelationship.

After the particular ingredients are pressed out of the container, they enter into spiral (3) for mixing that is placed in top carrier (2). By passing through the spiral the 150 ingredients are mixed together and on the exit from spiral (3) they come to the top made of spongy material (1), they soak it, and the pencil is ready for the hair dyeing.

The joining of body (6) and the top carrier (2) is made with groove (18) on the body and with the annular bulges on the inner side of top carrier (2), what enables the turning of top carrier (2) about the axis without increasing the distance between 155 this two parts. This enables an impermeable closing of the opening for pressing-out the dyeing ingredients by means of two annular seals (5).

Openings (19) and (20) on body (6) are placed out of the centre of body (6) in a way that the turning of top carrier (2) about its axis enables the pressing-out of the contents from the container in one position, while by turning top carrier (2) for about 160 45 degrees openings (19) and (20) are completely closed. In such a way the leaking of the ingredients and its mixing is prevented.

Top carrier (2) is made in such a way that in its opening on the front side the chosen top for the precise dyeing is inserted, or in it the pincers for the tuft dyeing can be placed, and this is in the same time a closer by which turning openings (19) 165 and (20) of the containers on body (6) are opened or entirely closed. In such a way the multiple uses, the dozing of the necessary amount of ingredients and the preserving of the container contents is enabled.

At the rear side of injector body (6) the rear part of body (9) is attached by means of groove (17) on the inner side of body (6) and annular bulge (17) on the rear 170 part of body (9). The rear part of body (9) serves for connecting body (6) with the assembly for pushing the pistons.

The inner wall of body rear part (9) is not entirely round but even in one part and against that even part leans the even part of nut (12) preventing the turning of nut (12) and securing in such a way its linear motion. Body rear part (9) leans against 175 alignment little plate (10) that serves for supporting axle (15) and keeping screw (11A) of little wheel (11) with the screw in the axial position.

The precise and quick folding of alignment little plate (10) is enabled by the groove in the form of the container wall on alignment little plate (10), which determines its position and in such a way aligns the openings through which pass 180 axles (15).

Rear part cover (13) serves for connecting the little wheel with the screw (11) and the injector, making the assembling simple. It is connected with body rear part (9) by means of the annular bulge and groove (16) on body rear part (9).

Little wheel (11) with the screw is connected with body rear part cover (13) by 185 securer (14).

For the precise dyeing of only individual hairs, into the opening of spongy rubber carrier (2) it is necessary to insert one of the extensions for the precise dyeing Vrh 1, Vrh 2, Vrh 3 or Vrh 4 (Fig. 4).

For dyeing the hair tufts it is necessary to exert top (1) for the precise dyeing 190 and to insert on top carrier (2) the pincers for the hair tufts dyeing.

Spiral for mixing ingredients After the particular ingredients are pressed out of the container in body (6), they enter into spiral for mixing (3) that is placed in top carrier (2). The spiral consists of interconnected segments made in spiral form, where each next segment has the 195 counter-winding spiral. So, first segment spiral (3A) winds from the left to the right. To it, next segment (3B) is connected at 90 degrees, which spiral winds from the right to the left, third segment (3A) has again a spiral winding from the left to the right and is made with a shift of 90 degrees to the preceding one, the second spiral segment (3B).

200 Each of the ingredients is pressed out in one half of the spiral and fills it, one ingredient fills the left channel of the spiral and the other ingredient fills the right channel of the spiral, and following its shape both ingredients arrive to the end of the first segment and meet the second segment that is placed in a way that his section axis intersects at 90 degrees the section axis of the first segment and divides the left 205 and right channel in two halves. Therefore, the half amount of the ingredient from the left channel and the half amount of the ingredient from the right channel enter and fill up the same upper channel of the second segment, and the half amount of the ingredient from the right channel enter into the second lower channel of the second segment. When they are pressed through several segments, the ingredients are 210 completely intermixed.

On the spiral periphery openings (3C) are made in a way that also during the pressing-through period through the spiral segments the ingredients pass from one channel into another and additionally intermix. Due to the fact that the pressure is equal in the ingredients that fill up the left and right channel, the pressing through the 215 openings is achieved in the following way. The openings in the walls of spiral (3C) are made in a way that, watching from the direction where the ingredients arrive into the spiral ; openings (3C) have a greater diameter than the openings on the opposite side of the wall. In other words, the cross-section of the openings has the shape of the truncated cone. As the pressure per unit area is equal, the greater area of the 220 opening at one side gives the greater sum of pressure per unit area. Therefore, the pressure at the side with the greater opening diameter overcomes the pressure on the opposite side, what enables the ingredient pressing-out through opening (3C).

The spiral of each segment turns for 150 degrees, what gives a sufficient length of the periphery for placing the opening for mixing (3C), and the channel of the 225 spiral has a sufficient length to enable the mixing of the components that arrived into it. At the end of the segment the edges are cut parallel with the longitudinal axis in order to avoid the thinning of the wall on the end and to prevent its breaking when being used, and also this reduces the vortices.

Pincers for dying hair tufts 230 If the dyeing of the hair tufts is desired, then the top for precise dyeing (1) is taken out and on top carrier (2) pincers for dyeing hair tufts are placed which consist of: pincers body (21) with lower pincers arm, pincers upper part (23) with opening lever (22) and upper pincers arm, axle (25) that connects pincers body (21) with pincers upper part (23) and enables the opening of the pincers, spiral spring (26) that 235 closes the pincers after being compressed during the opening of the pincers and secures the pressure of the spongy rubber of flat cross-section (24) on the tuft.

By putting pincers body (21) on top-carrier (2), spongy rubber of flat cross- section (24), which is of round shape in its rear part, enters into the opening of top carrier (2) and the pressed dye comes to it and soaks it. The front part of spongy 240 rubber of rectangular cross-section (24) is cut through into two pieces and the upper part is attached to the pincers upper arm that is a part of pincers upper part (23), while its lower part is attached to the lower arm that is a part of pincers body (21).

When the dye is pressed out of the container into body (6), it comes to spongy rubber of flat cross-section (24) and soaks it.

245 By pressing on lever (22) of pincers upper part (23), it rotates about axle (25) and the pincers arm open.

After the hair tuft that should be dyed is put in the pincers, lever (22) of pincers upper part (23) is released, spiral spring (26) presses pincers upper part (23) and they are closed. Then, spongy rubber of flat cross-section (24) soaked with dye 250 presses the hair tuft. By dragging the pencil over the tuft, the dye from spongy rubber of flat cross-section (24) remains on the tuft and dyes it.

Tops for precise dyeing Top 1 is of round shape with the semi-spherical ending, and it serves for a richer depositing of the dye. It is inserted into top carrier (2).

255 Top 2 is of round shape with the flat ending, and it serves for the precise depositing of the dye. It is inserted in top carrier (2).

Top 3 has a rear part that enters into the opening of carrier (2) of round shape, while its ending is flat. It consists of a set of thin threads and serves for a somewhat richer depositing of the dye. It is inserted into top carrier (2).

260 Top 4 with its front side is placed on top carrier (2). It has body (V1) of round shape and in it spongy rubber (V2) is placed that is soaked with the dye from the container. Body (V1) is partly open at the upper front side, and on this place little brush (V3) is pressed into spongy rubber (V2). Top 4 serves for dyeing smaller hair tufts.

265 Version B Injector for the hair dyeing using the single-component dye-stuff that is pressed out by turning the little wheel In injector body (B1) there is the container for the single-component hair dye- stuff, oval piston for dye pressing-out (B4) and the screw system for pressing the 270 piston. The little wheel with the application point and the inner threaded tube (B2) is made with the little wheel that is toothed for an easier rotation, and on the front side a tube with an annular bulge is made, by which it is connected with pencil body (B1).

By turning the little wheel with the application point and inner threaded tube (B2) also inner threaded tube (B2A) turns, which is its composing part. Tube with inner and 275 outer thread (B3), which is completely wound into the inner threaded tube of the little wheel (B2), comes out from it and presses oval piston with thread (B4), which turning is prevented just due to its oval shape. When tube with inner and outer thread (B3) due to the turning comes to the end of inner threaded tube (B2A), the bulge on the spring that is made on the begin of tube (B3) comes to the groove of rectangular 280 shape on inner threaded tube (B2A) of little wheel (B2) and fixes itself in it. By that, the turning of tube with inner and outer thread (B3) is stopped as well as its falling- out from inner threaded tube (B2A).

By a further turning of little wheel with the application point and inner threaded tube (B2) also tube with inner and outer thread (B3) turns, into which outer threaded 285 tube of oval piston (B4) is wound-in, to which due to the piston oval shape the turning is prevented and it presses piston (B4) linearly. To prevent the falling-out of outer threaded tube of oval piston (B4) from tube with inner and outer thread (B3), on the begin of outer threaded tube of oval piston (B4) a spring is also made with the bulge fixed in the rectangular groove that is made on the end of tube with inner and outer 290 thread (B3) just in the moment when outer threaded tube of oval piston (B4) has arrived to the end of the thread in tube with inner and outer thread (B3).

This pressing system is short and reduces the length of the invention, what is very important for the aesthetic appearance and simple handling.

Opening (B8) on body (B1) is placed out-of-centre with respect to the axis of 295 body (B1) in a way that the turning of top carrier (2) enables the pressing-out of the dye from the container in one position, while by turning carrier (2) for about 45 degrees the opening is completely closed. In such a way the leaking of the dye is prevented. Around pressing-out opening (B8) a groove is made, inside of which there is annular seal (B5) that ensures the impermeability.

300 Injector body (B1) is connected by means of groove (B6) with top carrier (2) that is made in a way that in its opening on the front side the selected top from precise dyeing is inserted, or on it the pincers of the precise tuft dyeing can be set.

Top carrier (2) is also the closer, by which turning opening (B8) of the container on body (B1) opens or completely closes. In such a way, a multiple use as well as the 305 storing of the container contents is enabled.

Version C Injector for hair dyeing using the single-component dye-stuff that is pressed out like an injection Injector body (C1) is of cylindrical shape and open at the rear side, in it there 310 is the container with the single-component dye and the piston for pressing-out the dye (C3). When piston (C3) is pressed, it presses out the dye from the container through opening (C5). At the rear side there is groove (C6) by which body (C1) is connected with rear part (C2) that serves as the cover for body (C1). On the front part of body (C1) opening (C5) is made, which is set out-of-centre with respect to the axis 315 of body (C1) in a way that by turning top carrier (2) the pressing-out of the dye from the container in one position is enabled, while by turning top carrier (2) for about 45 degrees opening (C5) is completely closed. In such a way the dye leaking is prevented, a multiple use is enabled as well as the storing of the container contents.

A groove is made around pressing-out opening (C5), inside of which annular seal 320 (C4) is placed, which ensures the impermeability between body (C1) and top carrier (2).

Top carrier (2) is attached by groove (C7) onto body (C1), which is made in a way that into its opening at the front side the selected top for precise dyeing is inserted, or on it the pincers of the tuft dyeing can be placed.

325 Version D Injector for the hair dyeing using two-component dye-stuff that is pressed out by turning the little wheel with the top for precise dyeing In injector body (D1) there are the containers with ingredients for the hair dyeing, and the container capacities can be various.

330 On the rear part there is little wheel with screw (D3). By turning little wheel (D3) also screw (D3A) is turning, which is its part. Pistons (D2) of piston pushing axle (D2B) and threaded little plate (D2A) are made as one part. Screw (D3A) is wound in into threaded little plate (D2A) and by turning screw (D3A) threaded little plate (D2A) moves linearly. Threaded little plate (D2A) is made in circular shape, where two 335 symmetrical sectors are missing. By these even parts it leans against the inner wall of body (D1), which two inner walls above the container are made as parallel planes.

In such a way the twisting of axle (D2B) is prevented. By the turning of little wheel with screw (D3) threaded little plate (D2A) of axle (D2B) is pushed, and so are pistons (D2) that press out the dye components.

340 After the individual ingredients are pressed out from the container, they enter into spiral for mixing (3) that is placed in top carrier (2). By passing through the spiral the ingredients are intermixed and on the exit from spiral (3) they come to the top made of spongy material (1), they soak it and the injector is ready for the hair dyeing.

Into the opening of top carrier (2) one of the extensions for the precise dyeing Vrh 1, 345 Vrh 2, Vrh 3 or Vrh 4 is placed, or for the tuft dyeing top for precise dyeing (1) is taken away and on top carrier (2) the pincers for tuft dyeing are set.

The connecting of body (D1) and top carrier (2) is performed with the groove on body (D1) and the annular bulges on the inner side of top carrier (2), what enables the turning of top carrier (2) about the axis without increasing the distance between 350 these two parts. This enables the impermeable closing of the opening for the pressing-out of the dyeing ingredients by means of two annular seals (5). The openings on body (D1) are placed out-of-centre with respect to body (D1) in a way that the turning of top carrier (2) about its axis enables the pressing-out of the contents from the container in one position, while by turning top carrier (2) for about 355 45 degrees the openings for pressing-out are completely closed. In such a way the leaking of the ingredients and their mixing is prevented.

At the rear side of injector body (D1) little plate (D4) is inserted which connects little wheel with screw (D3) with injector body (D1). It serves as a support to screw (D3A) and secures its position in the centre. It is of rectangular shape with a slot 360 having the width equal to the diameter of screw (D3A). The slot is made to the centre of little plate (D4), what enables to be inserted in body (D1) after into the latter pistons with axles and little plate (D2) are set and into them little wheel with screw (D3) is wound. Little plate (D4) is inserted into the slots in body (D1), which are cut in two inner walls of body (D1), which are made as two parallel planes.

365 Version E Hair dyeing injector for single use filled with single-component dye-stuff pressed out like an injection The body of the injector for single use (E1) is of cylindrical shape and serves as the container of the single-component dye-stuff and for the acceptance of top 370 (E2). It is fully open at the rear side, and on the front side it has an opening through which the dye is pressed out of the container. Into this opening top made of spongy material (E2) is inserted, which is soaked with dye. In body (E1), which serves as the dye-stuff container, also piston with axle (E3) is placed serving for pressing-out the dye. The axle of the piston before use, while the container is filled up with dye, 375 projects with the entire length out of the body and is protected by cylindrical shell (E4) that fixes the axle and gives a nicer aesthetical view. The top made of spongy material is protected by cover (E5).

At the use cover (E5) is taken off, injector body (E1) is caught between the thumb and the forefinger, and the rear, flat part of shell (E4) is put on the palm of the 380 hand. Injector body (E1) is pressed by the fingers towards the palm, and shell (E4) presses on the axle of piston (E3), so that the piston presses the dye out of the container in body (E1). The pressed out dye soaks the top made of spongy material (E2) that transfers the dye on the hair.

Version F 385 Hair dyeing injector for the single use filled with two-component dye-stuff, which is pressed out like an injection, with centrally placed containers.

Injector body (F1) for single use with centrally placed containers is of cylindrical shape and serves as the container of dye-stuff components. It is fully opened at the rear side, and at the front part on the inner side it has openings 390 through which the components are pressed out from their containers, and their ratio is determined by the diameter of the opening through which they are pressed out and by the area of pistons (F2A) and (F2B) and their mutual relationship. The containers are made in a way that the outer, cylindrical wall of body (F1) is also the outer wall of outer container (B). In its axis inner container (A) is built, which is also of cylindrical 395 shape but of smaller diameter, assigned for the placement of the other component.

Concentric pistons with axles (F2) that press out the components are made in a way that smaller piston (F2A), which is inserted into inner container A, is of round shape and in its axis is set the axle by which it is pressed. The piston entering into outer container (F2B) is also of round shape but in its centre it has an opening having 400 the size of the outer wall of inner container A. On it two symmetrically placed axles for pressing are built, which are on the rear side connected with the pressing little plate on which also the axle of inner piston (F2A) is connected. At the front side of body (F1) there is the cylindrical bore inside of which at the rear side spiral (F4) for mixing the pressed-out components is placed, and in front of it in the same bore at 405 the front side top made of spongy material (F5) soaked with dye is placed.

The axles of the pistons before use, when the container is full of dye-stuff, project with the full length outside the body and are protected by cylindrically shaped shell (F3) that fixes the axles and gives nicer aesthetical appearance. Top (F5) made of spongy material is protected by cover (F6).

410 At the use, cover (F6) is taken off, injector body (F1) is caught between the thumb and forefinger, and the rear, flat part of shell (F3) is placed on the palm of the hand. Injector body (F1) is pressed by the fingers towards the palm, and shell (F3) presses on the axles of concentric pistons (F2). Piston (F2A) and piston (F2B) press the components out of container A and container B to body (F1). The pressed-out 415 components enter into the spiral and during the pressing-through they are mixed, prepared in such a way they arrive to top (F5) made of spongy material, which transfers the dye onto the hair.

Version G Hair dyeing injector for single use filled with two-component dye-stuff that is pressed- 420 out like an injection with parallel placed containers.

Injector body for single use with parallel placed containers (G1) is of cylindrical shape, in it the containers for the dyeing components are placed. At the front side spiral for mixing (G4) and top (G5) made of spongy material are placed. At the rear side it is fully open and at the front side inside it has openings through which the 425 components are pressed out of the containers, and their mixing ratio is determined by the diameter of the opening through which it is pressed out and by the area of pistons (G2) and their mutual relationship. The containers are placed in the symmetry axis one alongside the other, and in the containers also pistons with axles (G2). The axles are built in the middle of pistons (G2) and connected with the pressing little 430 plates on their end.

At the front side of body (G1) there is the cylindrical bore in which at the rear side spiral (G4) is placed in which the pressed-out dyeing components are mixed. In front of it, in the same bore at the front side, top (G5) made of spongy material and soaked with dye is placed.

435 Axles with pistons (G2) before use, while the container is full of dye, are projected by the fully length outside body (G1) and protected by cylindrically shaped shell (G3) that fixes the axles and gives an aesthetically nicer appearance. Top (G5), made of spongy material is protected by cover (G6).

At use, cover (G6) is taken off, injector body (G1) is caught between the thumb 440 and forefinger, and the rear, flat part of shell (G3) is placed on the palm of the hand.

Injector body (G1) is pressed by the fingers towards the palm, and shell (G3) presses on the axles of pistons (G2), pistons (G2) press the components out of the container into body (G1). The pressed-out components are mixed in spiral (G4) and arrive to top (G5), the dye soaks top (G5) made of spongy material, which transfers the dye 445 onto the hair.

Elastic protecting ring The elastic ring with tube for the protection of the hair and tufts after dyeing consists of two half rings with arms, left half ring (P1) and right half ring (P2), reverse spring (P3), connecting axle (P5) and latex hose (P4).

450 In the released position half rings (P1) and (P2) are fit tightly in a way that they make a fully circle in which centre there is an opening that holds tight the tuft to be dyed. When the lever of left half-ring (P1) and the lever of right half-ring (P2) are pressed by two fingers, the moving away of the two-half rings (in a form of a sector) is achieved and the access to the central opening is opened. The hair tuft to be dyed 455 is drawn through such a made passage up to the central opening and the elastic protecting ring is lowered to the very hair root, and the levers of half rings (P1) and (P2) are released. Spring (P3) presses half rings (P1) and (P2) closing the ring and squeezing the tuft at the root. The latex or aluminium hose (P4), folded into a ring is drawn, over the tuft and drawn on annular stand (P6) formed by connecting left half 460 ring (P1) and right half ring (P2). After dyeing the tuft, latex or aluminium hose (P4) is spread by the fully length over the tuft, protecting the dye of a to quickly drying and the rest of the hair from undesired dyeing.

Way of invention application The invention with installed one of the tops for precise dyeing is applied for 465 dyeing only single grey hairs or smaller hair tufts, what has not been possible now without dyeing the entire hair. It also enables the dyeing of only one part of the hair that has grown after the last dyeing, as well as the dyeing of the tuft parts close to the skin, which usually remain undyed, or for dyeing the hair that has grown after the last dyeing of the tufts.

470 The invention with the extension (pincers) for dyeing the tufts enables a simple and quick dyeing of the hair tufts, at a simple preparation of the dye-stuff, precise and simple dosing of the ingredients, the multiple use, and it does not require any great specialisation or skill, what makes it suitable as for the professional so also for the domestic use.

475 The construction of the container enables the filling of various volumes and various mixing ratios of the dyeing ingredients, what in the combination with various piston areas and openings through which the liquid is being pressed out from the container enables a precise dosing and mixing of dyeing components in a correct ratio. The way of opening and closing enables a multiple use and the storage of 480 various ingredients, which by that can be mixed in correct ratios.

Several body constructions and pressing-out ways enable the filling with the single-component or multi-component dyes, while various versions of the pressing- out and dye mixing ways enable a simpler and by that cheaper or a somewhat more complex realisation, but which requires a very little preparation and by that a little 485 consumed time, and it is very simple for use.

The invention elastic ring with the latex or aluminium protection hose is applied at dyeing the hair tufts, for protecting the hair that should not be dyed from the contact with the dyed hair, as well as for the protection of the dye on the dyed tuft from a quick drying, what would interrupt the dyeing process. The simple and quick 490 preparation of the hair tuft and the later protection after depositing the dye accelerates the work manifoldly and requires much less skill.

The invention of the injector for single use enables a quick and simple dyeing of single hairs or a smaller part of grown (undyed) hair, without applying the protection from dye dirtying, at the use of the single-or multi-component dye.
