Laser hair removal only works when the hair is darker than the surrounding skin. Coarse, dark hair responds the best to laser treatment. With light skin, fewer treatments are required and better results are obtained. Tanned patients should wait until their tan fades before attempting treatment. The DMC Sinai-Grace Cosmetic Center has two different lasers, one for fairer skinned patients and one for darker skinned patients. For people with darker skin, results are slower because more sessions are needed.
