A laser produces a beam of highly concentrated light that is absorbed by the pigment in the hair follicles. It pulses for a fraction of a second and vaporizes the pigment, disabling numerous follicles to eliminate or significantly impede hair growth. Healthy hair grows in three stages. First, the growing or anagen stage. Second, the resting or telogen stage. Third, the transitional or catagen stage. Laser treatment destroys active follicles. Over the course of laser hair removal multiple sessions you will see hair become progressively lighter and finer as the laser gradually destroys the follicle. You can expect to see 75% to 95% reduction in hair growth over the course of your treatment.
