What is the principle of laser hair removal?

The principle of laser hair removal is the destruction of hair follicles by releasing heat from the laser, thereby achieving the effect of hair loss. The specific process of the operation is to first remove the hair that needs laser processing, using a scraper, so that the laser can better level hair root, and then go down the hair to the position of the hair follicle. The heat secreted by the laser begins to play the role in damage to the hair follicles, and the repetition of this step can ultimately achieve the effect of hair removal several times.
