Abstract: The present invention relates to a cosmetic treatment and processes for treating keratinous materials, in particular for altering the color of hair as in hair coloration, hair color lightening or removal, and treatment of artificially colored hair, wherein the composition can include at least one antioxidant, applied separately or combined or combinable with one or more components of a color altering system in amounts sufficient to confer protection when the treatment composition is applied to keratinous material and thereby enhance and protect one or more sensorial features, and preserve the mechanical properties and native amino acid structure of the keratinous material.

Abstract: The present disclosure relates to hair coloring agents and compositions, and methods for improving the quality and durability of color in artificially colored hair. The compositions employ divalent metal salts of inorganic acids, monovalent or divalent metal salts of organic acids, antioxidants, and colorants. Methods are described wherein hair is contacted with the compositions of the present disclosure, resulting in improved artificial color deposition, as well as improved quality and durability of the color in artificially colored hair.

Abstract: The present disclosure relates to compositions and methods for improving the quality and durability of color in artificially colored hair. The methods employ pre-color treatments containing divalent metal salts of inorganic acids; monovalent or divalent metal salts of organic acids; and antioxidants, wherein the pre-color treatments are applied to hair prior to artificially coloring hair.

Abstract: Disclosed are compositions and agents for treating keratinous fibers including a polycarbodiimide compound in various combinations with a carboxylic acid, an amine and a carboxysilicone polymer in order to improve the quality of the keratinous fibers such as hair. In particular, agents, kits, and methods for imparting protection to hair and/or minimizing hair damage caused by extrinsic and intrinsic factors and for improving the condition of or repairing damaged hair are disclosed.

Abstract: The present disclosure relates to hair care compositions such as hair restructuring compositions comprising a combination of restructuring components. The compositions are unique because they dramatically improve the quality and durability of hair, especially chemically treated hair. Typically, the compositions include: (a) one or more amines selected from the group consisting of diamines, polyamines, alkylamines, alkanolamines, and mixtures thereof; (b) one or more unsaturated carboxylic acids of formula (I): wherein R1 is a linear or branched C2-C10 alkenyl group; R2 is a linear or branched C1-C10 alkyl group; and R3 is (meth)acryloyloxy; and (c) a cosmetically acceptable carrier.
