How long between laser hair removal sessions?

The hair growth cycle is divided into growth phase, degenerative phase and resting phase (dormant phase). Laser hair removal is only effective for hair in the growth phase. When the hair is in the growth phase, the cell activity is strong, melanin accumulates, and the light absorption rate reaches 75%. For the anagen and telogen phase, laser hair removal cannot completely remove the hair in these periods. Therefore, if you want to finish laser hair removal and get better hair removal effect, it usually takes 3-5 times to achieve permanent hair removal.

It is best that the interval between each laser hair removal is 30 to 45 days, because the hair follicle is generally 30-45 days from the anagen phase to the growth phase. That is to say, after one hair removal, the hair in the growth period will fall off, but there are other non-growth hairs that will not fall off. The hair will enter the growth period from the resting period in 30-45 days. At this time, you need to do laser again. Hair removal treatment can also have a better hair removal effect.
