The hair on our body grows in cycles. There are three phases of hair growth per cycle. They are:
- Anagen
- Catagen
- Telogen
The first phase of the cycle is when hair removal works. It is the only phase of the cycle where the hair is still attached to the follicle. The heat from the Laser then travels down the shaft of the hair and penetrates the follicle. When this happens, the heat will destroy the follicle and it will no longer be able to produce hair. There is usually no more than about 20% to 30% of our hairs in the Anagen phase at any given time. This is one of the main reasons why a person needs multiple treatments for Laser hair removal. On a mans’ face this growth can be up 80% at once, resulting in excellent treatments.
