The present invention relates to an anhydrous liquid dyeing composition comprising one or more oil liquid at 20° C., one or more oxidative dye precursor, at least one anionic and at least one nonionic surfactant for achieving intensive homogeneous colors on hair.

A composition for oxidative hair treatment, containing 50-96% by weight; 0.5-20% by weight hydrogen peroxide; at least one polyethylene glycol ether of a monoester of glycerol and a C12-C22 carboxylic acid having 110-500 ethylene oxide units in the molecule, according to formula (I), wherein the sum of the indices x+y+z stands for a number in the range of 110 to 500, and R stands for an alkyl functional group having 11 to 21 carbon atoms, which may be saturated or unsaturated, linear or branched, wherein all stated quantities are based on the weight of the oxidation composition. Wherein the composition is suited for use as a developer for oxidative hair lighteners and/or hair dyes. The alkaline composition (A) is present as an oil-in-water emulsion and includes at least one alkalizing agent, and has a pH in the range of 8 to 11.5.

A cosmetic product includes a cosmetic preparation including, relative to the total weight thereof, 50 to 90 wt. % polar solvent, and 0.001 to 10 wt. % direct dye. The product also includes a device for flash evaporation of the cosmetic preparation.

Described herein is a method for treating and coloring hair including un-pigmented hair. The method includes (a) providing a first composition including one or more heavy metal ion sequestrants; (b) applying the first composition to the hair; (c) providing a second composition including one or more weak acids having a pKa from 2.5 to 5; (d) applying the second composition to the hair; (e) providing a third composition including one or more direct dyes chosen from nitro dye, disperse dye, cationic dye, acid dye, basic dye, neutral azo dye and mixtures thereof, and (f) applying the third composition to the hair. The third composition is able to decrease the reflectance of un-pigmented hair in a wavelength range from 530 nm to 670 nm.

The disclosure relates to compositions for treating keratinous substrates, such as the hair, comprising monoethanolamine and at least one carboxylic acid, as well as systems and methods for treating keratinous substrates with the compositions.

A method for reducing skin staining during the coloring of hair includes the following steps in the indicated sequence: A1) applying a coloring agent (F) to the hair, A2) allowing the coloring agent (F) to act for a time period from 30 seconds to 45 minutes, B1) applying an undiluted cleaning agent (R) to skin areas that can come into contact with the coloring agent (F) when the latter is washed out, C1) jointly washing out the coloring agent (F) and cleaning agent (R), wherein the coloring agent (F) includes at least one oxidation dye precursor and/or at least one direct dye and the cleaning agent (R) includes at least one anionic surfactant.

A multicomponent packaging unit includes the coloring agent (F) and the cleaning agent (R).

The present invention relates to an anhydrous dyeing composition which is liquid at 20° C. and comprising one or more oil liquid at 20° C., one or more direct dyes and at least one anionic surfactant and at least one nonionic surfactant for achieving intensive homogeneous colors on hair.
