Abstract: The instant disclosure relates to methods and kits for artificially coloring hair and improving the durability of the artificially colored hair. The methods include: (I) combining an antioxidant booster composition, a hair coloring base composition, and a developer composition to form an antioxidant-enriched hair coloring composition within 2 hours of application to the hair; (II) applying the antioxidant enriched hair coloring composition to the hair and allowing the antioxidant enriched hair coloring composition to remain on the hair for a period of time; and (III) rinsing the antioxidant enriched hair coloring composition from the hair. The antioxidant booster composition can be included in a kit with a hair coloring base composition and/or a developer composition, wherein the antioxidant booster composition, the coloring base composition, and the developer composition are separately contained.

Abstract: The present disclosure relates to methods for treating hair with lactones. The lactones form a covalent thio-ester bond with free thiols groups on chemically treated hair, and thereby impart a “repairing” or “conditioning” effect to the hair, for example, by making the hair more hydrophobic. Typically, after hair has been treated with a composition comprising one or more reducing agents that reduce disulfide bonds of hair to free thiols, a composition comprising one or more lactones is applied to the hair and the one or more lactones react with the free thiols to form a covalent thio-ester bond. Treatment with the lactones prevents reversion of the repaired bonds to their free thiol state after a single application.

Abstract: The present disclosure relates to methods for improving the quality and durability of color in artificially colored hair. The methods employ alkaline earth metal salts that act as a mordant (a fixing agent) with the dye and hydroxy-polycarboxylic acids, which act as chelators. The artificially colored hair is treated with a post-color treatment composition comprising one or more alkaline earth metal salts and one or more hydroxy-polycarboxylic acids. Also, the one or more alkaline earth metal salts may be incorporated into a coloring composition for coloring the hair (in-color treatment composition) and a subsequent post-color treatment composition comprising one or more hydroxy-polycarboxylic acids can be applied to the 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 alkaline earth metal salts that act as a mordant (a fixing agent) with hair dye and salts of hydroxy-polycarboxylic acids, which act as chelators. Methods are described wherein the alkaline earth metal salts or the salts of hydroxy-polycarboxylic acids are used in a pre-color treatment (a treatment to the hair prior to artificial coloring), used as part of a coloring composition, and used in a post-color treatment (a treatment to the hair after artificial coloring).

Abstract: The present disclosure relates to methods for inhibiting color fading in hair and for improving the color durability and stability of artificial color of hair. The methods entail forming a layer-by-layer (LbL) film on hair, and optionally forming a cationic surface layer on the LbL film. The LbL film is formed by applying a cationic silane layer on the hair and subsequently applying an anionic polymer layer on the cationic silane. Multiple cationic silane layers and anionic polymer layers can sequentially be added as desired. Finally, the LbL film may comprise a cationic surface layer.
