A new composition for hair dyeing includes an amino acid, a protein, an alcohol, a mineral powder, a vegetable oil and a dye or a pigment, as well as a method for dyeing hair implementing said composition.

The present invention relates to an anhydrous composition comprising at least one amino silicone, at least one alkoxysilane of formula (VIII), and at least one coloring agent chosen from pigments, direct dyes and mixtures thereof. The present invention also relates to a process for treating keratin fibers such as the hair.

The present invention relates to a process for bleaching keratin fibers, in particular human keratin fibers such as the hair, comprising a step of applying, to said fibers, an oxidizing composition comprising hydrogen peroxide and a non-peroxygenated ammonium salt with a molar mass of greater than 40 g/mol and a step of irradiating said fibers with UV-visible radiation having a wavelength ranging from 200 to 800 nm and a fluence ranging from 1 to 5000 J/cm2, after application of said oxidizing composition.

A hair treatment kit comprises a hair treatment composition selected from the group of semi-permanent oxidative and/or direct dye hair colorant compositions, hair bleaching compositions, highlighting compositions, and combinations thereof, a reservoir for holding the temporary hair treatment composition, and an applicator fluidly connected to the reservoir for selectively applying the hair treatment composition to a targeted area of hair. Methods of applying the hair treatment composition comprise selectively engaging the applicator with a targeted area of hair, leaving the hair treatment composition in the targeted area for a time period, washing the hair treatment composition out of the targeted area, closing the reservoir to preserve remaining hair treatment composition for later use, and reapplying the hair treatment composition to the targeted area.

This invention relates to an oxidative hair cream composition that contains at least one oxidative hair cream ingredient and at least one thiophene azo colorant.

Peptides are provided herein, wherein the peptide bearing one or more amino acid sequence differences relative to SEQ ID NO: 1, with the amino acid sequence differences comprising at least one cysteine replacement.

The present invention is directed to the provision of a kit-of-parts, a dyeing composition, and a method for dyeing keratin fibres. The kit comprises separate compositions A and B and optionally separate composition C. Composition A comprises a direct dye and an alkalising agent. The aqueous composition B comprises guanidine and/or its salts together with one or more lipophilic compounds and/or one or more thickening polymers. Composition C comprises a persalt and/or persulfate salt. A method for dyeing keratin fibres comprises mixing compositions A and B, and optionally C, to yield a ready-to-use composition with pH in the range of 7 to 12. Composition B may be used for enhancing colour intensity and/or wash fastness of a direct dye on keratin fibres with the provision that it is mixed with composition A directly prior to application.

The subject of the present disclosure is a process for dyeing keratinous material, in particular human hair. The process includes applying a first composition (A) to the keratinous material. The first composition includes (A1) one or more organic C.sub.1-C.sub.6 alkoxysilanes and/or condensation products thereof, and (A2) at least one colorant compound selected from the group of pigments and direct dyes. A second composition (B) is applied to the keratinous material. The second composition (B) includes (B1) Tannic acid.

A process for preparing a cosmetic composition useful for treating keratinous material, in particular human hair, is disclosed. The process comprises preparing a first agent (A) by reacting one or more aminoalkyl-C.sub.1-C.sub.6 alkoxysilanes (a1) with water (a2), preparing a second agent (B) by reacting one or more alkyl-C.sub.1-C.sub.6 alkoxysilanes (b1) with water (b2), and mixing together the first agent (A) and the second agent (B), thereby preparing the cosmetic composition. A cosmetic composition prepared by the process, as well as a method of using the cosmetic composition for treating keratinous material (e.g. coloring human hair) are also disclosed.

A process and a kit-of-parts for dyeing keratinous material such as human hair are provided. An exemplary process includes applying an agent (a) to the keratinous material. The agent (a) includes (a1) at least one organic silicon compound. The method further includes applying an agent (b) to the keratinous material. The agent (b) includes (b1) at least one coloring compound comprising at least one effect pigment comprising a substrate platelet and a coating. The coating includes at least one layer wet-chemically prepared using a metal alkoxide and an organosilicon compound having a basic group. The agent (b) further includes (b2) at least one film-forming polymer.
