Method for coloring hair with removable hair color

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 —S—S— bonds on the hair fiber surface to form reactive —SH groups; and (ii) a dye molecule containing chemical groups reactive with the —SH groups on the hair fiber surface to form —S—S— 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 —S—S— 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 —S—S— linkage, comprising applying to the hair an aqueous based color removal composition containing a reducing agent capable of disrupting the —S—S— bonds between the dye and hair fiber surface.
