We use The DiolazeXL lasers that concentrates energy beams on the hair follicles during their growth stage. The pigment in the hair follicles absorbs the energy of the laser, which disables or destroys the hair follicle. Disabled or damaged hair follicles can no longer grow strong hair. What hair they do grow is weak. From client to client the time varies in which it takes to have desired results. Most clients need an average of 6 sessions to before they stop noticing new hair growth.
