Abstract: A method for coloring hair and removing the color from the hair when desired, comprising coloring the hair with an aqueous hair color composition comprising, in combination: (i) a reducing agent capable of reducing the nullSnullSnull bonds on the hair fiber surface to form reactive nullSH groups; and (ii) a dye molecule containing chemical groups reactive with the nullSH groups on the hair fiber surface to form nullSnullSnull bonds between the dye molecule and the hair fiber surface when the hair color composition is applied to the hair at ambient conditions; wearing the colored hair for the desired period of time; and then removing the color from the hair by contacting the hair with an aqueous based color removal composition containing a reducing agent capable of disrupting the nullSnullSnull bonds between the dye molecule and the hair fiber surface to cause the dye molecule to become disassociated from the hair fiber; and a method for removing dye bonded to the hair fibers via an nullSnullSnull linkage, comprising applying to the hair an aqueous based color removal-composition containing a reducing agent capable of disrupting the nullSnullSnull bonds between the dye and hair fiber surface.
