摘要：
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.
