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).
