A hair browning composition is capable of browning the hair without damage to the scalp and hair due to the absence of an alkaline agent, an oxidizing agent, and an aromatic amine-based compound having an improved hair browning effect and a prolonged browning effect-lasting period. The composition includes gallic acid, magnesium ascorbyl phosphate, and tromethamine.

Compositions containing a combination of nicotinamide riboside and pterostilbene for treating skin disorders, and methods of treating skin disorders using these compositions and their equivalents are described. The skin disorders that are treated using these compositions or methods include sun exposure-related skin disorders, inflammatory skin disorders, autoimmune disease-related skin disorders and cancer-related skin disorders. In one embodiment, the compositions containing a combination of nicotinamide riboside and pterostilbene are prepared as oral formulations.

The present invention relates to a process for dyeing keratin fibres, in particular human keratin fibres such as the hair, in which said fibres are treated using one or more cosmetic compositions comprising a) one or more dyes chosen from synthetic direct dyes and dyes of natural origin, b) one or more titanium salts and b1) optionally one or more particular carboxylic acids, c) one or more cellulose-based polysaccharides, d) optionally one or more organic compounds that are liquid at 25° C., with a Hansen solubility parameter value δH<16 (MPa).sup.1/2 at 25° C., e) optionally one or more chemical oxidizing agents such as hydrogen peroxide or one or more hydrogen peroxide-generating systems.

Provided are an evaluation method for objectively evaluating the glow of the skin, a skin glow improver, and a method for examining skin glow improvers. This method for evaluating the glow of the skin comprises assessing the specular reflectance and diffuse reflectance of skin after polarized light is applied to the surface of the skin, and determining that glow is present in the skin when prescribed conditions are satisfied. A skin glow improver is provided by combining an alkali metal salt of alkoxysalicylic acid and trimethylglycine. This method for examining skin glow improvers makes it possible, using a significant decrease in surface roughness as an indicator, to examine samples capable of improving the specular reflectance of the skin.
