The subject of the present application is an agent for the oxidative dyeing of keratinous fibers, in particular human hair, which contains the coupling oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol in combination with the oxidation base 2-(2,5-diaminophenyl)ethanol, wherein the pH of the agent is higher than 8.0.

The subject of the present application is an agent for the oxidative dyeing of keratinous fibers, in particular human hair, which contains the coupling oxidation dye precursor 2-(1,3-benzodioxol-5-ylamino)ethanol in combination with the oxidation base 4,5-diamino-1-(2-hydroxyethyl)-1H-pyrazole.

The instant disclosure relates to hair coloring base compositions and developer compositions that can be incorporated into a hair color cartridge, which combines the compositions and dispenses them onto hair. The hair color cartridge includes: (a) one or more hair coloring base compositions and; (b) one or more developer compositions, which can be combined to form an active hair coloring composition and dispensed onto hair. The hair coloring base compositions typically include one or more oxidative dye precursors; one or more alkalizing agents; one or more reducing agents; optionally, one or more cationic conditioning polymers; one or more surfactants; one or more water-soluble solvents; and water. The developer compositions typically include one or more oxidizing agents; one or more surfactants; and water. The unique components and fluid characteristics of the various compositions are such that devices or appliances comprising them accurately combine and dispense the hair coloring base composition(s) with the developer composition(s) in a predetermined ratio with excellent consistency for application to hair.

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.

Still further, the present invention relates to a system for neutralizing relaxed hair. Yet further, the invention relates to relaxed hair neutralized by the compositions and methods disclosed herein. The present invention also relates to compositions and methods to simultaneously neutralize and color relaxed hair.

The present invention relates to a composition for dyeing keratin fibres, comprising: (a) at least one 2-amino-5-ethylphenol coupler, or an addition salt or solvate thereof, and (b) at least one oxidation base 3-(2,5-diaminophenyl)-1-propanol and/or the addition salts thereof or solvates thereof. The invention also relates to a process for dyeing keratin fibres using this composition. Finally, the invention relates to the use of such a composition for dyeing keratin fibres, and in particular the hair.

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.
