    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 hair care compositions for chemically treating hair, to kits comprising the compositions, and to methods for treating hair with the compositions. The compositions include one or more polymeric acid compounds and/or polymeric acid anhydride compounds in addition to one or more active agents for chemically treating the hair. Additionally, the compositions can optionally include one or more non-polymeric, mono-, di-, and/or tri-carboxylic acids and/or one or more mono- and/or di-amines and/or polyamines. Hair treated with the compositions exhibits improved softness, smoothness, and discipline.

    Abstract: The present disclosure relates to hair care compositions such as hair restructuring compositions and composition for chemically treating hair comprising restructuring components. The disclosure also relates to methods for using the compositions to treat hair. The compositions and methods are unique because they dramatically improve the quality and durability of chemically treated hair. Typically, the compositions include at least: (a) one or more non-polymeric, mono-, di-, and/or tri-carboxylic acids; (b) one or more amines; and (c) one or more polymeric acid compounds and/or polymeric acid anhydride compounds.
