The Hair Growth Cycle in hair follicle can be divided into 3 phases: - Anagen phase, Categen phase and Telogen phase which keeps circulating. The traditional hair removal treatments with the use shavers and tweezers, can only eliminate hair temporarily while the hair follicle still remains inside the skin. Also, the use of chemical substance, like the hair removal cream can only dissolve the hair structure which cannot damage the hair follicle. Instead, the hair will grow again due to metabolism. As a result, all these treatments cannot be seen as permanent method for hair removal.
There are many ways for hair removal. However, the laser treatment is the only permanent method to do so. The laser treatment for hair removal is based on the principle that it uses a specific wavelength light beam absorbed by the melanin in the hair and causes the heat damage to the hair follicle tissues. As a result, it can delay or stop the hair growth. In general, people with pale skin, thick and black hair, can absorb large amounts of laser radiation which shows better effect. On the contrary, it is more difficult for hair removal for those whose hair is light-colored or fine. Medical professionals believe that women with dark skin can take advantages from laser hair removal. However women with a tan would not be suitable for laser treatment on the other hand.
Tanning skin would probably burn your skin. With the penetration of laser energy into the cortex, not only hair will absorb the energy, but also melanin surrounded follicles will also be affected which results in burning. In general, doctors will use 755nm or 810nm wavelength while the 1064nm wavelength is more suitable for dark skin.
The whole treatment can be ranged from 4 to 8 times, once every 6 to 8 weeks which depends on the hair, treatment parts and hair growth cycle.
