Abstract

There is disclosed a method of coating mammalian hair, the method comprising applying, on the external surface of individual hairs of the mammalian hair, an oil-in-water emulsion comprising: (i) an aqueous phase containing water; and (ii) an oil phase containing at least one water-insoluble reactive condensation-curable film-forming amino-silicone pre-polymer that, subsequent to condensation curing, forms an elastomer. The reactive oil phase may further contain a plurality of sub-micrometer pigment particles dispersed therein. Suitable compositions and kits including the same are also disclosed, as well as methods for preparing the compositions.

Description

technical field [0001] The present disclosure relates to compositions and kits for dyeing keratin fibers such as hair. Methods of preparation and use thereof are also disclosed. Background technique [0002] Natural hair color is the pigmentation of the hair follicle due to two types of melanin, eumelanin and pseudomelanin. Generally, if more eumelanin is present, the hair will be darker in color; if less eumelanin is present, the hair will be lighter in color. The level of melanin can change over time, causing changes in hair color. [0003] The production of melanin in the roots of human hair decreases with age, causing the hair to lighten and eventually stop. Once the production of melanin stops, new hairs grow and turn gray or white when light reflects through them. [0004] Hair coloring is the practice of changing the hair. The main reason for this practice is makeup (for example, to cover black hair, to change to a color considered more fashionable or desired, or...
