Why does laser depilation need a course of treatment

About depilation, it’s really the pain point of every mm. In order to be beautiful and endure the taste of depilation cream, I tried the trouble of shaving knife, but the annoying hair is stronger and stronger year by year. I want to try laser depilation, but the problem arises again. Why does laser depilation need a course of treatment? Now let’s listen to the experts.

Expert answer: most hair removers who choose laser, after 3-5 courses of treatment, more than 95% of the cases have 80% of the hair falling off, the hair becomes less and thinner, the color is lighter, and the growth speed is slower. Reduce hair by 50-2% only if the treatment is outdated.

Laser hair removal generally takes three to six times, mainly due to two factors:

First: most hair follicles are tied together in groups of three and open in the same pores. A hair in the pores is the hair growing from one of the three hair follicles in the group below it. Therefore, one treatment can only destroy one hair follicle in a group;

Second: hair growth should go through the growth period, degenerative period and resting period. Laser hair removal in the growth period is 75% effective, the degenerative period is 25%, and the resting period is almost invalid.

What is the number of laser hair removal related to?

  1. Hair can be divided into three periods: growth period, degenerative period and quiescent period. The energy emitted by the laser instrument can only destroy the hair follicles in the growth period and has no obvious effect on the hair in the degenerative and quiescent period. Only after these hair turn into the growth period can the laser work. Therefore, laser hair removal needs many times of treatment and the effect can be obvious.
  2. If the proportion of a certain part of hair in the growth period is small, the number of treatments should be increased. On the contrary, the number of treatment can be reduced.
  3. Based on different parts of hair, there are different growth cycles, and the interval of each treatment is also different. If the head hair has a relatively short rest period, the interval can be as short as 1 month; The hair rest period of trunk and limbs is relatively long, so the treatment interval should be about 2 months, so you can easily enjoy the confidence brought by silky skin.
