Laser Hair Removal is not determined by age, rather, by hair color. As long as the hair has a dark pigment it can be lasered. Once hair starts to turn gray or white, the laser will no longer be able to “see” the hair and will not be effective on those specific hairs. If you are thinking about laser hair removal and the hair is still dark, Go For It! If there is a mix of grays, whites and darks the laser will reduce the dark hair but will not be effective on the white and gray hair.
