Alexandria laser hair removal (common name: fiber optic laser hair removal)
Principle: The wavelength of the laser is 755nm, which can transmit energy to the hair follicle and destroy the subsequent growth ability of the hair follicle. After sufficient number of treatments, hair growth can be inhibited for a long time. Because of the remarkable hair removal effect, it is the mainstream instrument for hair removal treatment at present.

Hair growth cycle
Growth phase: Alexandria laser only treats hair in the growth phase.
Regression period: Although the hair still stays on the skin, the Alexandria laser does not respond to the hair in this period.
Resting period: At this time, a slight movement of the hair will cause hair loss, and Alexandria laser has no effect at this stage.
Growth phase recovery: About 1/3 of the hair is in the growth phase, and the rest are in the other three phases. Each time you apply it, there is only a partial effect. In addition, some extremely strong hair follicles need multiple treatments.
