Laser Hair Removal works best on light-skinned people with dark hairs. But even people with dark skin can have laser hair removal. Your skin will heat up some during treatment. How much it heats up depends on your skin and hair color. Controlling the length and intensity of pulses controls the amount of heating. Although dark-skinned individuals can be treated, people with blonde or grey hairs that lack melanin can be very hard to treat. These hairs may need to be removed with an alternate method.
