What removes hair dye?

Sorry dear, but no. You can put a product called "Stripper" in your ahir which removes color, but leaves your hair being a random light color depending on what color your hair was dyed and what the natural color is. After you put the stripper in your hair you would get a new color and re-dye your hair to the closest possible color to what you want it to be. you will than have to let your hair grow out until you get your natural color back.
