Laser hair removal

The hair growth phase is clinically divided into three stages: growth phase, resting phase and telogen phase. When people use laser hair removal, it only works on the hair that is in the growth phase and the resting phase. That is to say, only hair in these two periods can absorb laser energy, allowing this energy to destroy the hair follicles and achieve permanent hair removal effects. Lasers have no effect on hair that is in the resting phase. Therefore, the remaining hair can only be removed during the next growth phase and resting phase. Therefore, laser hair removal needs to be performed several times, rather than all at once.

The density and thickness of each person's hair will result in different times of hair removal. Generally, 3-4 times of hair removal are required. The reasons are mainly the following two points:

First, hair follicles are usually bundled in groups of three, opening into the same pore. Each hair grows from one of the three follicles, so each treatment can only destroy one follicle in a group.

Second, hair growth mainly goes through three periods: growth phase, regression phase, and resting phase. The effectiveness of laser hair removal treatment during the growth phase is 75%, 25% during the regression phase, and basically ineffective during the resting phase.
