Products for the oxidative dyeing of hair in copper shades with improved gray coverage

The invention relates to a method for dyeing keratin fibers, in particular human hair, in which alter applying and allowing a thickened pre-treatment agent in the form of a lightening or bleaching agent (M1), comprising at least one oxidation agent, to react, a dye (M2) is applied directly and is allowed to react without rinsing. By carrying out said method, hair can be colored in a dyeing step and simultaneously multi-tonal dyeing with highlights is achieved.

Preparation (A) includes, in a cosmetic carrier, (a1) at least one oxidation dye precursor and (a2) ammonia, and preparation (B) includes, in a cosmetic carrier, (b1) hydrogen peroxide, (b2) at least one fatty alcohol from the group comprising arachidyl alcohol (eicosan-1-ol), gadoleyl alcohol ((9Z)-eicos-9-en-1-ol), arachidonyl alcohol ((5Z,8Z,11Z,14Z)-eicosa-5,8,11,14-tetraen-1-ol), heneicosyl alcohol (heneicosan-1-ol), behenyl alcohol (docosan-1-ol), erucyl alcohol ((13Z)-docos-13-en-1-ol), and/or brassidyl alcohol ((13E)-docosen-1-ol), and (b3) at least one hydrocarbon having 8 to 80 C atoms.

Multi-component packaging unit for oxidatively dyeing keratin fibers, having reduced ammonia odor

An agent for oxidatively dyeing keratinous fibers, in particular human hair, includes &#x2014;in a cosmetic carrier&#x2014; A second subject matter of the present invention is a corresponding multicomponent packaging unit (kit-of-parts).

Fashionable copper shades in a nonionic base

A method for dyeing keratinous fibers, in particular, human hair, in which, after a thickened pre-treatment agent (M1) containing no oxidation dye precursors has been applied and allowed to react, a coloring agent (M2) is applied and allowed to react immediately thereafter and without rinsing. By carrying out said method, hair can be colored in a dyeing step and simultaneously multi-tonal dyeing with highlights or lowlights can be achieved.

A method for the oxidative dyeing of keratinic fibers includes the following steps: Cosmetic agent (M1) includes Cosmetic agent (M2) includes

Multi-tonal one step dyeing with foam-type pre-treatment solution

A method for dyeing keratin fibers, in particular human hair, in which, after a thickened pretreatment agent (M1) including at least one oxidation dye precursor has been applied and left to act, directly thereafter and without rinsing a coloring agent (M2) is applied and left to act. By virtue of this method, in one dyeing step the hair can be colored and at the same time a multi-tonal dyeing with lighter ('highlights') or darker ('lowlights') sections (strands) can be produced.

Multi-tonal one step dyeing with thickening pre-treatment solution

An agent for dyeing and/or bleaching keratin fibers, in particular human hair, including in a cosmetic carrier (a) at least one fatty alcohol selected from the group of arachyl alcohol (eicosan-1-ol), gadoleyl alcohol ((9Z)-eicos-9-en-1-ol), arachidonic alcohol ((5Z,8Z,11Z,14Z)-eicosa-5,8,11,14-tetraen-1-ol), heneicosyl alcohol (heneicosan-1-ol), behenyl alcohol (docosan-1-ol), erucyl alcohol ((13Z)-docos-13-en-1-ol) and brassidyl alcohol ((13E)-docosen-1-ol), (b) at least one persulfate salt selected from the group of ammonium persulfate, potassium persulfate and sodium persulfate, and (c) at least one glyceryl fatty acid ester of general formula (I), in which R1, R2 and R3 independently of one another stand for a hydrogen atom or a grouping of formula (II), in which R4 stands for an unbranched or branched, saturated or unsaturated C-Calkyl group, with the proviso that at least one and at most two of the radicals selected from R1, R2 and R3 stand for a grouping of formula (II).
