The present disclosure relates to a method for styling mammalian hair fibers, including providing body, straightening, relaxing, curling, or applying any other desired modification to the shape of the hair. The method comprises applying a hair styling composition comprising at least one thermally-curable polyol monomer to the hair, allowing the monomers to penetrate within the hair and curing such monomers to internally form a polymer able to overcome the tendency of the hair to revert to its native shape. When curing is performed while the hair is in a desired modified shape, the resulting polymers may maintain the modified shape. Suitable compositions and kits allowing to prepare the same are also disclosed.

The present invention relates to the use, for dyeing or lightening keratin fibres, in particular human keratin fibres such as the hair, of a hand-held styling apparatus (1) equipped with at least one treatment surface (2d, 3d) partially or totally covered with at least one substrate (6) comprising a surface (6a) coated with at least one layer (6b) containing one or more dyes, preferably chosen from oxidation dyes and/or direct dyes, and/or one or more oxidizing agents. The invention also relates to an assembly (11, 24, 26) intended for dyeing or lightening keratin fibres, in particular human keratin fibres such as the hair, comprising at least one aqueous composition and at least one hand-held styling device (1) as defined above.

Disclosed herein is an agent for shaping or altering the shape of hair, such as by straightening or relaxing hair, the agent comprising: A. a hair treatment composition containing an alkaline material selected from a hydroxide-containing compound and a carbonate compound; a cationic polymer selected from a quaternary diammonium polycondensate; an amphoteric polymer selected from a quaternary ammonium compound; an organic solvent, and water; and optionally, B. an activator component; wherein the pH of the composition is equal to or greater than 12 and wherein the weight ratio of (b) to (c) ranges from about 1 up to about 3.

The invention includes methods of forming a semi-permanent film on a fiber comprising topically applying an effective amount of a composition to the hair and exposing the hair to a temperature of about 50° C. or greater thereby forming a film on the hair. The composition comprises a chitosan, an aldehyde-bearing compound, and an organic acid. Also included are the compositions that form the film, specifically compositions that form a semi-permanent film on a fiber in the presence of heat comprising a chitosan, an aldehyde-bearing compound, and an organic acid. Other, related methods are within the scope of the invention.

A method of protecting hair from damage by applying a long-chain unhydrolyzed alkyltrialkoxysilane to hair shafts and then hydrolyzing and polymerizing the alkyltrialkoxysilane to form a non-penetrating outer layer on the hair shaft by utilizing pH adjusted water followed by the application of heat. Alternatively, the alkyltrialkoxysilane may be applied to the hair in combination with an alkyl or alkenyl succinic anhydride prior to the application of heat.
