Laser hair removal can be used, which is based on the rich melanin in hair follicles and hair shafts. Melanin is distributed between cells in the hair bulb matrix, and can also be transferred to the structure of hair shaft (such as medulla, cortex and cuticle). Laser can accurately and selectively target melanin for hair removal treatment. After absorbing the energy of laser, the temperature of melanin rises sharply, which leads to the destruction of surrounding hair follicle tissue and the removal of hair.
