Abstract: Disclosed are methods for coloring hair, comprising applying a mixture comprising one or more hair dyes and an additive as a pre-treatment, as a simultaneous treatment, as a post-treatment, or a combination thereof.

Abstract: Provided are hair treatment compositions comprising a polyurethane-urea crosslinked by at least one multi-functional chain extender, and uses thereof.

Abstract: Provided herein are long lasting hair styling compositions and markers for selecting the same.

Abstract: Disclosed are methods of preparing thiol keratin-containing materials, comprising applying a mixture comprising one or more thiol compounds and a catalyst. Methods of preparing cross-linked keratin-containing materials by applying a mixture comprising one or more thiol compounds and an oxidizing agent are also disclosed. Methods of grafting monomeric and polymeric materials on keratin-containing materials to provide a covalent coating on keratin-containing materials are disclosed. A mixture comprising one or more thiol compounds is applied to the keratin-containing material sample. The keratin-containing material sample then comprises a plurality of free thiol groups. A monomer is optionally applied to the keratin-containing material sample to form a plurality of covalent bonds between the free thiol groups and the monomers. The disclosed grafting methods can be carried out with or without catalyst.

Abstract: Provided herein are color protectant compositions for dyed human hair, and methods for determining the same.

Abstract: Provided herein long lasting cosmetic compositions and markers for selecting the same.

Abstract: Hair spray compositions comprising a liquid carrier, hollow, fluid-filled microspheres, a polymer fixative, and propellant are provided.

Abstract: Disclosed are methods of grafting monomeric and polymeric materials on keratin-containing material to provide a covalent coating on keratin-containing material. A mixture comprising a reducing agent is applied to the keratin-containing material sample. The keratin-containing material sample then comprises a plurality of free thiol groups. A monomer is applied to the keratin-containing material sample. The free thiol groups react with the monomer to form a plurality of covalent bonds between the free thiol groups and the monomers. The reducing agent and the monomer can be applied separately, semi-simultaneously, or simultaneously. The disclosed methods can be carried out with or without catalyst. The disclosed methods can be carried out with or without an additive.
