Our laser targets hair cells responsive for hair growth without harming the surrounding skin. This only works on dark hair. It does not work on light, blonde, or grey hair so it is best to treat before hair turns grey. Three to five treatments are required, spaced 4-6 weeks apart because hair grows in cycles, and must be in their active androgen growth phase for the laser to work. Many women experience excessive hair growth triggered by hormone fluctuations seen after menopause. You can expect to see a gradual decrease in hair thickness and the amount of hair in the area.
