Nowadays, many people who love beautiful women are deeply troubled by excessive and dense body hair. They see the weather turn hot day by day, but there is nothing they can do. Indeed, the hair removal products on the market can not have a permanent effect, so now many beauty lovers will choose to do laser hair removal. In fact, laser hair removal can achieve the effect of permanent hair removal after a course of treatment. How many times does it usually take? Let’s take a look at this.
Laser hair removal is generally based on the principle of selective thermodynamics and the use of laser technology. The light beam emitted by the laser machine will penetrate the surface of the skin and eventually be absorbed by the hair follicle. Through the selective absorption of laser energy, the hair follicle will be damaged and can not regenerate long hair without damaging the surrounding tissue. The process of laser hair removal is simple and fast. Generally, there is no scar after treatment.
The principle of laser hair removal is to remove hair by destroying hair follicles, and hair follicle growth is divided into growth period, resting period and degenerative period. There are many melanins in the hair follicles during the growth period, which have strong absorption of the light emitted by the laser, so they have become the target of the laser hair removal machine. The more melanin, the more clear, the higher the hit rate, and the greater the damage to hair follicles. Laser has little effect on degenerative hair follicles, but not on resting hair follicles. Laser hair removal generally needs 3 to 6 courses of treatment to achieve the purpose of permanent hair removal! If you want to depilate, you must adhere to the course of treatment to have a good depilation effect!
