摘要： The present disclosure relates to hair-treatment compositions, typically in the form of an oil-in-water emulsion, comprising: (a) one or more monosaccharides with amine group(s); (b) one or more polysaccharides with amine group(s); wherein (a) and (b) are solubilized in an aqueous phase of the oil-in-water emulsion; (c) one or more oils; (d) one or more nonionic emulsifiers; and (e) water. The compositions strengthen hair fibers and provide additional cosmetic improvements to the hair such as conditioning, detangling, softness, suppleness, moisturizing, and manageability. Methods of treating hair with the compositions are also described. The methods include applying the composition to wet or damp hair, drying the hair (for example, with a blow dryer) and treating the hair with heat (for example, with a hot iron).

摘要： Hair treatment compositions, kits for producing such hair treatment compositions, and methods for using such kits and/or hair treatment compositions are provided for treating hair. Methods for treating hair typically include: obtaining a first composition comprising one or more polysaccharides with amine group(s) and water; adding ascorbic acid and one or more peroxides, peroxo compounds, or combinations thereof to the first composition to obtain a second composition; applying the second composition to hair; and heating the hair, which has the second composition applied thereto, to a temperature above 25° C. Kits for improving hair typically include a first composition comprising one or more polysaccharides with amine group(s) and water; a second composition comprising up to 100 wt. % of ascorbic acid; and a third composition comprising a peroxide, a peroxo compound, or a combination thereof, wherein the first composition, the second composition, and the third composition are separately contained.
