The laser emits a beam of light that is absorbed by the pigment in the hair follicles. The energy from the laser damages the hair follicle, slowing down or stopping the growth of new hair. The laser can treat multiple hair simultaneously, making it a quick and efficient way to remove hair from large areas such as the legs, arms, or back. Laser hair removal is suitable for all skin types but is most effective on dark and light skin individuals. It may not be as effective for those with blond, red, or grey hair, as the laser targets the pigment in the hair follicles and may not be able to distinguish between the hair and surrounding skin.
