    Abstract: Disclosed herein are compositions suitable for styling hair. Certain compositions comprise a. at least one alkoxysilane having at least one solubilizing functional group and at least one amino substituent; and b. at least one carboxylic acid-containing latex film former. The at least one alkoxysilane may be neutralized by the at least one carboxylic acid-containing latex film former. Also provided are method of using same.

    Abstract: The present disclosure relates to compositions and methods for improving the quality and durability of color in artificially colored hair. The methods employ salts of hydroxy-polycarboxylic acids. The salts of the hydroxy-polycarboxylic acids are incorporated into a pre-color treatment composition (a composition applied to the hair prior to coloring the hair) or added directly to the coloring composition (in-color treatment composition). The salts add alkalinity to the coloring process. Hydroxy-polycarboxylic acids are incorporated into a post-color treatment composition (a composition applied to the hair after coloring the hair). The salts and the acids act as chelators, fixing the dye molecules to the hair, thereby imparting color fading resistance to the hair.

    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.
