Disclosed is a method of treating non-keratinous fibers using a composition comprising an amide and/or alkyl ammonium carboxylate salt wherein the treating method improves the robust performance of the non-keratinous fibers and simultaneously maintains and/or improve the appearance or look such as color, shine, form, and shape of the fibers even after prolonged use. The method of protecting colored non-keratinous fibers from fading using the composition comprising an amide and/or alkyl ammonium carboxylate salt is also disclosed.
