Laser hair removal is a widely used method in current hair removal methods. Many people have a misunderstanding about laser hair removal. They think that laser hair removal needs one treatment to achieve long-term hair removal effect. In fact, it’s wrong to think about it. Laser hair removal is a hair removal method that destroys hair follicles by laser irradiation, so as to achieve the effect of hair removal. So, can laser hair removal be completed at one time?
Hair growth is generally divided into growth period, degenerative period and quiescent period. Hair in the growth stage contains more melanin and is extremely sensitive to laser; The hair in the degenerative and quiescent phase does not absorb the energy of the laser. Therefore, laser hair removal treatment can only work after these hairs turn into the growth period, so laser hair removal needs repeated treatment to achieve obvious results.
Laser hair removal has different growth cycles based on different parts of hair, and the time interval of each laser hair removal treatment is also different. If the stationary period of head hair is relatively short, the interval is about 1 month; The rest period of trunk and limb hair is relatively long, with an interval of about 2 months.
Can laser hair removal be completed at one time?
In general, laser hair removal requires an interval of about 4-8 weeks between each course of treatment. The next laser hair removal treatment is feasible only after new hair grows out. Different individuals, different parts and different hairs have different times and intervals of laser hair removal treatment. Generally, after 3-5 times of treatment, all patients can get long-term hair loss. Even if there is a small amount of regeneration, the regenerated hair is thinner, shorter and lighter than the original.
The current laser hair removal treatment can not completely destroy all hair follicles at one time, but a slow, limited and selective destruction. Therefore, it is suggested that patients should communicate with beauticians before laser hair removal, so as to avoid having great expectations for laser hair removal, but they are disappointed that one-time treatment of laser hair removal can not achieve long-term hair removal effect.
