Abstract: The disclosure relates to compositions for altering the color of keratin fibers and methods of using the compositions. The compositions comprise (a) a bonding system comprising (i) at least one first bonding agent chosen from lactic acid and/or salts thereof, and (ii) at least one second bonding agent chosen from amino acids and/or salts thereof; (b) at least one fatty alcohol; (c) at least one fatty acid; (d) at least one alkyl polyglucoside; (e) at least one alkalizing agent; and (f) at least one solvent. The compositions can further comprise one or more oxidation dyes, couplers, oxidizing agents, or combinations thereof.

Abstract: The disclosure relates to compositions and methods for removing color from keratin fibers such as hair. The compositions comprise (a) at least one reducing agent chosen from glutaric acid, glyoxylic acid, thiolactic acid, thioglycolic acid, glycolic acid, or combinations of two or more thereof, (b) optionally, at least one amine compound, and (c) at least one solvent.

Abstract: The instant disclosure relates to methods for removing color from artificially colored hair. The methods include a two-step process: (I) applying a reducing composition to hair that has been colored with oxidation dyes and rinsing the reducing composition from the hair; and (II) applying an alkalizing composition to the hair and rinsing the alkalizing composition from the hair. The step can be carried out in either order. The methods effectively remove color from artificially hair in a quick and gentle manner without employing an oxidizing agent.
