The answer to this depends on your skin type (color) and the color of the hair.   If your skin is darker, look for someone who does a lot of hair removal and has a YAG based hair removal system.  But........ the hair still has to be dark.  Laser hair removal systems don't work well (still) on gray or blond hair.   If your skin is lighter and the hair is darker, then look for a Lumenis Lightsheer system or even an Alexandrite system (older system but works well).    Dr. I
