A soluble needle (100) for hair transplantation, wherein the soluble needle (100) comprises a fixing plate (30) and a plurality of micro-needles (20) made of water-soluble polymers arranged on the fixing plate (30), wherein each of said micro-needle (20) comprises a needle wall (21) to penetrate scalps and a needle cavity (22) confined by the needle wall (21) and configured for accommodating a hair follicle. A method of manufacturing a soluble needle (100) for hair transplantation, wherein the method includes: dissolving water-soluble polymers in water to prepare a molding solution (S101); delivering the molding solution into a mold (S102); letting the molding solution settle in the mold to shape (S103); and separating and removing the mold to produce the soluble needle (S104).
