The Cool Glide laser hair removal technology effectively destroys the hair follicles without harming the surrounding skin. We ask you to shave the treatment area before your laser hair removal treatment to better target the hair follicles. The treated area may be a little red afterward, which typically goes away in a matter of hours. A good candidate for laser hair removal treatment is someone with pale to medium skin tone with light brown to dark hair. No laser hair removal or light based system can treat blonde, white, red or gray hair since there is not enough melamine in the hair follicle to absorb the light.
