Laser hair removal is a highly effective method to reduce hair, it works because of the incidence of laser rays, in the form of light, in the hair follicle.
Melanin attracts the laser and destroys the hair follicle which ends up preventing a new hair from developing. That's why laser hair removal is only effective on dark hair.
