The present invention relates to a hair treatment method including the following step (i) and step (ii) in this order: Step (i): a step of applying a composition containing the following component (A) on a hair: (A) a compound represented by the following general formula (1) or a salt thereof: ##STR00001## wherein a broken line represents the presence or absence of a π bond; R.sup.1 represents a hydroxy group or an acetoxy group; R.sup.2 represents a hydrogen atom or —COOR (R is a hydrogen atom, a methyl group, or an ethyl group); and R.sup.3 represents a hydrogen atom, an acetyl group, a methyl group, or an ethyl group; and Step (ii): a step of giving a shape to the hair while applying a temperature of 140° C. or higher and 220° C. or lower to the hair.

Provided are indigo darkener, containing: in parts by weight, 0.1-99 of indigo dye, 0-99 of alkaline dyeing assistant, 0.01-99 of acidic dyeing assistant, and 0-99 of oxidizing agent, and hair dyeing process using the indigo darkener. The multi-layer scales on the surface of hair are opened at large angles under alkaline condition and/or high-temperature condition, so that large indigo dyeing particles are easily absorbed in the scales; black indigo oxocarbon or carbon black is generated under the action of alkaline dyeing assistant and oxidizing agent at high temperature by the property that the indigo dye is easy to oxidize; the acidic dye assistant is added as the temperature decreases, and the scales having opening angles on the surface of hair are closed under acidic condition, so that the indigo carbide is firmly clamped and fixed in the scales of hair; finally, the blue indigo dyes white hair into black.

The present invention describes compounds and uses thereof in applications relating to absorption of electromagnetic energy. Preferred compounds are double bond-containing compounds capable of absorbing electromagnetic radiation energy and having improved properties.

It is an object of the present disclosure to provide an agent for coloring keratinous material, in particular human hair, comprising (a1) at least one amino-functionalized silicone polymer, and (a2) at least pigment,
the weight ratio of all the pigments (a2) contained in the composition to all the amino-functionalized silicone polymers (a1) contained in the composition, i.e., the weight ratio (a2)/(a1), being not more than 0.95.

A second subject matter is a method for dyeing keratin material, wherein the agent is applied to the keratin material.

An effective treatment for dandruff and seborrheic dermatitis, a composition for treating dandruff, and a method for making such a composition

Disclosed is a confectionery product for instant optical tooth whitening comprising artificial and/or natural dyes and characterised by the ability to produce an immediate whitening effect after extremely short contact times with the teeth.

A process for dyeing keratinous material is disclosed. The process includes applying an agent (a) and an agent (b) to the keratinous material. The agent (a) comprises (a1) at least one organic silicon compound, and (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound. A multi-component packaging unit is also disclosed, and comprises, separately packaged, a first container comprising an agent (a′), a second container comprising an agent (a″), and a third container comprising an agent (b). The agent (a′) comprises (a1) at least one organic silicon compound. The agent (a″) comprises (a2) at least one sulfated and/or sulfonated fatty acid ester. The agent (b) comprises (b1) at least one sealing reagent, and (b2) at least one first colorant compound.

The present invention relates to the preparation of 9-deoxo-36,37-dihydro-prolylFK506, 9-deoxo-31-O-demethyl-36,37-dihydro-prolylFK506, 9-deoxo-prolylFK520 or 9-deoxo-31-O-demethyl-prolylFK520, which are novel compounds that can be utilized as the main ingredient of a composition for promoting hair growth, and the use thereof in promoting hair growth.

The invention relates to a composition comprising melatonin, a metabolite or derivative thereof and coenzyme Q10 and to use thereof for the production of a pharmaceutical or cosmetic composition for the treatment of the skin, said composition potentiating the movement of both molecules into the mitochondrion and facilitating percutaneous absorption, in which both the melatonin and the CoQ10 can reach all of the strata of the skin.

The present invention relates to a pharmaceutical composition for preventing or treating hair loss, a health functional food composition or a cosmetic composition, including a specific compound or a pharmaceutically acceptable salt thereof as an active ingredient, wherein the compound exhibits an excellent hair growth recovery effect in hair follicle tissues in which hair growth is inhibited without cytotoxicity, and thus hair loss can be more effectively prevented, improved, or treated.
