The skin microbiota balancing agent can be configured to provide at least two of the following desired ratios: a first desired ratio of Corynebaderium to Staphylococcus of 1.3, a second desired ratio of Corynebaderium to Micrococcus of 1.4, and a third desired ratio of Staphylococcus to Micrococcus of 1.1. The carbohydrate sources may be D-alanine, D-threonine, L-alanyl-glycine, succinic acid, α-keto-glutaric acid, m-tantaric acid, bromo succinic acid, mucic acid, phenylethyl-amine, inulin, oxalic acid, pectin, Tween 40 etc.

The present invention relates to a composition for dyeing keratin fibers, in particular human keratin fibers such as hair, comprising one or more oxidation dyes, one or more scleroglucan gums in a total weight content greater than or equal to 0.5% relative to the total weight of the composition, —one or more alkaline agents selected from amino acids, the amino acid(s) being present in a total weight content greater than or equal to 1% relative to the weight of the composition, and preferably one or more additional alkaline agents, preferably selected among the mineral alkaline agents and/or alcanolamines. The invention also relates to a method for dyeing keratin fibers using said composition and to a multi-compartment device suitable for implementing said composition according to the invention.

A hair-dyeing composition with an effect of minimizing hair damage and scalp irritation caused by ammonia prescription and ammonia odor, which is capable of decreasing ammonia odor peculiar to a hair-dyeing composition and also of supplementing the hair with amino acids similar to hair proteins to decrease hair damage, especially hair roughness and hair shortening, for healthy dyeing and a method of producing the same.

A UV protection cosmetic composition is provided. The composition may include an organic UV protection agent, a thickening agent, a silicone elastomer, ethanol and oil.

The present disclosure relates to hair care and conditioning compositions comprising polyols; monoalcohols having from 2 to 6 carbon atoms; fatty alcohols selected from cetyl alcohol and myristyl alcohol; cationic surfactants; fatty carbonate esters; and dialkyl ethers. When the composition is applied to the wet or damp hair or put in contact with extraneous water, the composition forms an emulsion having a lamellar phase. The present disclosure also relates to methods of treating hair using these compositions.

The present invention relates to a cosmetic or dermatological composition in the form of an emulsion, comprising: (a) a fat-soluble photoprotective system consisting of one or more fat-soluble UV filter(s) selected from: (i) hexyl 2-[4-(diethylamino)-2 hydroxybenzoyl]benzoate, (ii) 2,4-bis[4-(2-ethythexyloxy)-2-hydroxyphenyl]-6-(4-methoxyphenyl)-1,3,5-triazine, (iii) butyl methoxydibenzoylmethane, (iv) ethythexyl triazone, and (v) diethylhexyl butamido triazone: (b) a solubilising system of the fat-soluble photoprotective system (a), comprising C12-C15 alkyl benzoate in a quantity greater than or equal to 80% by weight, preferably greater than or equal to 90% by weight, relative to the total weight of the solubilising system; and (c) one or more particulate organic UV filters, which are in particular hydro-dispersed and are selected from: (vi) 5,6,5′,6′-tetraphenyl-3,3′-(1,4-phenylene)-bis[1,2,4]triazine, (vii) methylene bis-benzotriazolyl tetramethylbutylphenol, (viii) tris-biphenyl triazine; characterised in that: —the fat-soluble photoprotective system (a) constitutes between 3% and 19% by weight, preferably between 5% and 15% by weight, relative to the total weight of the composition; —and —the solubilising system (b) constitutes between 15% and 30% by weight, relative to the total weight of the composition; the composition not comprising ethylhexyl salicylate, octocrylene, ethylhexyl methoxycinnamate, isoamyl methoxylcinnamate, homosalate, para-aminobenzoic acid (PABA), octyl dimethyl PABA, 3-methylbenzylidene 30 camphor, 4-methylbenzylidene camphor, benzophenone-3 and/or benzophenone-4.

The invention concerns a method for straightening keratinous fibers including: (i) a step of applying on the keratinous fibers a hair straightening composition containing at least one polyhydroxylated aromatic compound, (ii) a step of increasing the temperature of the keratinous fibers, using heating means, to a temperature ranging between 110 and 250° C.

The present disclosure concerns a hair care agent for the oxidative colouring or bleaching of hair, as well as a gentle method for the oxidative colouring or bleaching of hair, in which keratinous fibres are protected from oxidative influences.

Disclosed are m-aminophenol-free hair-colouring compositions comprising a mixture of dyes consisting of methoxymethyl-p-phenylenediamine, hydroxyethyl-3,4-methylenedioxyaniline and 5-amino-6-chloro-o-cresol, an alkalising agent, and optionally other oxidative dyes, provided that they are not p-phenylenediamine or p-toluenediamine
