QUESTION: I want to color my hair golden or brown to attract my husband. some people told me that my wadu will not be valid after coloring my hair because of certain chemical ingredients present in colors. Do I need to check and research about ingredients before using hair color, or I can just use the branded hair colors easily available without worrying about the ingredients?
