How Laser Hair Removal Works
Laser energy is selectively absorbed by the melanin in the hair follicle and converted to heat, injuring the follicle.
Most hair is permanently removed. Hair that does regrow is finer and lighter than before.
How Hair Removal Works
Three phases of normal hair growth:
- Anagen (active)
- Catagen (regression)
- Telogen (resting)
Follicle most susceptible during anagen phase:
- 1/3 to 2/3 of hair is in Anagen phase at any time
- Hair has most melanin in the bulb during Anagen phase and absorbs the most energy to disable stem cells
