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.

Hair-care agent and method for oxidative hair dying or bleaching with selected dicarboxylic acids

The present disclosure concerns colouring agents for keratinous fibres, in particular for human hair, which&#x2014;with respect to its weight&#x2014;contain at least one compound selected from the group formed by oxidative dye precursors, direct dyes and mixtures thereof, from about 0.1 to about 5% by weight of dicarboxylic acid(s) containing from about 2 to about 10 carbon atoms and/or salt(s) of this(these) acid(s), from about 20 to about 95% by weight of water, and less than about 0.1% by weight of peroxy compound(s), to produce oxidative colouring agents with improved protection of fibres.

Gentle agents and methods for oxidative dyeing using selected dicarboxylic acids

A first subject of the present disclosure is a special oxidant preparation for oxidative coloring of keratinous fibers, more particularly human hair, included in a cosmetic carrier Additional subjects of the present disclosure are methods for oxidative color changing of human hair in which this special oxidant preparation is used.

Oxidation agent preparations

The subject of the present disclosure is a method for coloring of human hair, comprising the following steps in the specified sequence A) Mixing a first component (K1) with a second component (K2) to produce a first mixture (M1), B) Mixing the mixture (M1) with a third component (K3) to produce a second mixture (M2), C) Application of the mixture (M2) on the hair, D) Allowing the mixture (M2) to take effect for a period of from about 30 seconds to about 45 minutes, E) Rinsing the mixture (M2) from the hair, wherein 

Method for dyeing keratin fibers

The object of the present disclosure is a method for dyeing human hair which is adapted to the differing degrees of damage along the length of the hair fiber and achieves more homogenous coloring results.

Method for homogenously dyeing keratinous fibers

The aim of the present disclosure was to provide an improved oxidizing agent preparation for oxidative color modifying agents, which are present as soap based gels and contain ammonia as the alkalizing agent and optionally at least one oxidation dye precursor, and have a pH in the range of from 8 to 11.5, measured at 20&#xb0; C., with which homogeneous and viscosity-stable application mixtures can be produced that release less ammonia during the entire leave-in time. It was surprisingly found that aqueous hydrogen peroxide preparations which contain selected 1-alkanols, glyceryl fatty acid esters, ethoxylated fatty alcohols, polyols and oils, achieve said aim in a very satisfactory manner.

Odor-reducing developer for oxidation dyes

The present invention relates to an agent for oxidatively coloring or blonding hair that is gentle on the hair, and to a gentle method for oxidatively coloring or blonding hair, in which keratin fibers are protected from oxidative influences.

Oxidative coloring or blonding agent gentle on hair, and gentle hair coloring or blonding method

An agent for oxidative hair coloring or bleaching, which is gentle on the hair, and a gentle method for oxidative hair coloring or bleaching, in which keratin fibers are protected against oxidative effects.

Agent and method for oxidative hair coloring or bleaching, which are gentle on hair

An agent for coloring and/or lightening keratinic fibers, in particular human hair, includes:
