The subject matter of the present disclosure are agents for oxidative hair lightening or hair coloring, containing 70-90% by weight of a total of % water, oxidation dye precursor(s), alkalizing agent(s), and a certain mixture of a crosslinked copolymer of acrylic acid and non-ethoxylated esters of acrylic acid with linear C10-C30 monoalcohols, anionic surfactant, cationic or zwitterionic polymer and linear, saturated C8-C22 alkan-1-ol, and sodium polyacrylate, giving the whitening or coloring agent an application-optimal viscosity and the consistency of a gel-like cream with an excellent feel.

The problem of the present disclosure is to impart manageability and flexibility to hair after being dyed or bleached using an oxidative hair dye or a hair bleaching agent. The features for solving the problem are a first agent of an oxidative hair dye or a hair bleaching agent comprising: (A) a polyvalent carboxylic acid having no hydroxyl group or a salt thereof; (B) a surfactant including (B1) a cationic surfactant and (B2) a nonionic surfactant; (C) an oily component; and (D) an alkaline agent.

The present invention relates to a melanogenesis detection method using FAM86A, and the like. The level of FAM86A of the present invention decreases according to an increase in the amount of melanin secretion or formation, and thus the present invention can whiten the skin by using protein FAM86A or an agonist thereof, and can prevent, treat or alleviate melanin-deficiency diseases such as vitiligo since the formation and secretion of melanin is promoted when FAM86A is inhibited. Therefore, the present invention is expected to be used in various ways, such as a composition for skin whitening using protein FAM86A or an agonist thereof, and as a composition for preventing and treating melanin deficiency diseases including vitiligo and canities by using a FAM86A inhibitor.

Methods and multi-component packaging units (kit-of-parts) for dyeing keratinous material such as human hair are provided. A method for dyeing keratinous material includes applying a first composition (A) and a second composition (B) to the keratinous material. The first composition (A) includes (A1) at least one organic C.sub.1-C.sub.6 alkoxysilanes and/or condensation products thereof, and (A2) at least one colorant compound selected from the group consisting of pigments and direct dyes. The second composition (B) includes (B1) a copolymer of (meth)acrylic acid and maleic acid (anhydride).

A semi-permanent colorant composition is provided that is exhibits excellent color deposit without heat or oxidative treatment, and resists fading throughout several washes.

Compositions, kits, and methods for repairing bonds, for example, disulfide bonds, in hair or on the skin are disclosed. The compositions provide improved conditioning benefit for dry hair or moisturize the skin. The compositions also provide a long lasting moisturized feel and smooth feel to the skin or hair, without feeling greasy. The compositions contain one or more compounds that covalently bind at least two thiol groups in the hair or on the skin. Use of the binding compositions prevents reversion of the repaired bonds to their free thiol state, for at least one week or one month, or more, after a single application of the composition. Improved methods of styling hair, for example permanent hair waving, hair curling, hair coloring or highlighting, and hair straightening, are also provided.

The invention relates to a cosmetic active ingredient comprising at least one extract of Avena strigosa and at least one extract of Ononis spinosa. The invention also relates to a composition including it, a method for obtaining it and the use of this cosmetic active ingredient, in particular for its anti-graying effect on the hair.
