The present invention relates to a method for dyeing hair fibres, in particular a method which involves coating hair fibres with a hair dye composition and directing radio frequency electromagnetic radiation to the coated hair fibres to cause heating within the coated hair fibres by dielectric loss. The present invention also relates to kits and appliances for use in connection with the method, as well as the use of radio frequency electromagnetic radiation in reducing the effective dye-treatment time for hair fibres. In one aspect, there is provided a method of dyeing hair fibres, said method comprising the steps of: i) coating one or more hair fibres with a hair dye composition; and ii) directing radio frequency electromagnetic radiation having one or more frequencies from 1 MHz to 300 MHz to the one or more coated hair fibres to cause heating within the one or more coated hair fibres by dielectric loss. Preferably, the hair dye composition used in step i) is a permanent or demi-permanent hair dye composition that may be prepared by combining a dye lotion containing one or more dye precursors and an activator solution containing an activating agent, wherein the activating agent in the activator solution converts the one or more dye precursors in the dye lotion to active dye agents.

The present invention relates to a cosmetic process for treating keratin materials, in particular keratin fibers, preferably human keratin fibers such as the hair, using a) one or more direct dyes which are preferably neutral and b) one or more particular aliphatic ammonium salts, and to a composition comprising ingredients a) and b). The cosmetic process for treating keratin materials of the invention makes it possible to obtain a good color build-up up and, furthermore, the colors are vivid and chromatic.

The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in one or more steps, comprising the application to said keratin fibres of a composition comprising one or more compounds of formula (I) and/or (II), and also to the use thereof for dyeing keratin fibres, and to a device: in which formula (I) or (II) R.sub.1, R.sub.3, R.sub.4, R.sub.5, R.sub.6, and n are as defined in the description. The compounds of formula (I) according to the invention can give powerful, chromatic and sparingly selective colourings with good colour build-up, which are resistant to the various attacking factors to which keratin fibres may be subjected, such as inclement weather, light, washing and perspiration. ##STR00001##

The present invention features novel cosmetic skin care compositions for improving the appearance of flushed or rosacea-affected skin.

The present invention provides a novel substance that promotes expression of filaggrin gene involved in improvement of the moisture retention function of skin. The inventors of the present invention found that expression of filaggrin gene fluctuates rhythmically over a roughly 24 hour cycle, screened candidate substances based on the time at which expression reaches a maximum following addition of the candidate substance, and identified zanthoxylum extract, 3-(1′-piperidine)propionic acid, geranium oil, cypress oil, rose oil, galvanum oil, pepper oil, basil oil, methyl-o-toluate, methyl anthranilate and dimethyl anthranilate as filaggrin gene expression promoting agents.

Agents for oxidatively dyeing of keratinic fibers include in a cosmetic carrier, (A) as a developer, 4,5-diamino-1-(2-hydroxyethyl)-1H-pyrazole and/or one of the physiologically acceptable salts thereof, (B) as a developer, p-aminophenol and/or one of the physiologically acceptable salts thereof, (C) as a coupler, 2,6-bis(2′-hydroxyethylamino)-1-methylbenzene and/or one of the physiologically acceptable salts thereof, and (D) as a coupler, at least one m-dihydroxybenzene derivative from the group consisting resorcinol, 2-methylresorcinol and/or 4-chlororesorcinol as coupler.
