OK I’ve been lurking here for a while and gained fair enough information about laser and other kinds of hair removal.
I know that laser can induce hair in some parts of the body and the hair is supposed to be dark and coarse in order for laser to be effective. What I don’t understand is how laser might induce hair in the upper arms and shoulders for example if the hair there is already dark colored ? laser should eliminate this type of hair right ? and induced growth should not be noticeable in that case.
