Hair Removal I have heard about laser therapies to remove hair. Lasers hair removal is the newest method to come down the pipeline. Contrary popular belief, it does not work for everyone. Also, while the results can become permanent, this is not guaranteed, nor will the desired effect be achieved in one session.
Laser is an intense beam of light.
When it strikes an area, the light is drawn to the darker or pigmented parts. If the darkest part is the hair, then the heat and energy of the light beam will be concentrated on the hair. The temperature will become high enough to kill the hair follicle. But, the laser only works on hair follicles in the active phase of growth. Hair goes through other phases as well.
