Present invention relates to an oxidative dyeing composition having especially mild properties to the scalp. The object of the present invention is an oxidative dyeing composition for hair comprising at least one dyestuff and avenathramide and/or its derivative.

Oxidative dyeing composition

Present invention relates to an oxidative dyeing composition having especially mild properties to the scalp. The object of the present invention is an oxidative dyeing composition for hair comprising at least one dyestuff and allantoin and/or its derivative.

Aqueous oxidizing composition

Present invention relates to a hair coloring process which allows visualization of the color to be achieved prior to coloring hair using a sheet () comprising two or more areas () having each different natural hair color.

Hair coloring process

Present invention relates to a two part coloring composition for hair with improved dyeing and conditioning properties of hair. The object of the present invention a two part hair dyeing composition consisting of Parts A and B which are mixed immediately before application onto hair wherein Part A is based on at least one hair dye and comprising further at least one amino acid surfactant and Part B is an aqueous composition and comprising at least one oxidizing agent and at least one cationic or cationizable surfactant, wherein parts A and/or B comprises additionally at least one oil.

Two-part hair colouring composition

Present invention relates to a dyeing composition for hair with improved dyeing and conditioning properties of hair. The object of the present invention a composition for dyeing hair based on at least one hair dye and comprising at least one amino acid surfactant and at least one natural oil.

Hair colouring composition

A composition and method oxidative colors hair based on at least one oxidative dye precursor and comprises at least one fatty acid soap, preferably selected from sodium, potassium soaps and their mixtures. The composition is preferably applied onto hair as foam from a non-aerosol foamer vessel after mixing with a composition comprising at least one oxidizing agent.

Composition and method for colouring hair

A composition and method oxidative colors hair based on at least one oxidative dye precursor and having effervescent properties. An aqueous oxidative hair dyeing composition resulting from mixing two aqueous compositions A and B wherein the mixed composition has a pH below or equal to 7.0, preferably is in the range of 2 to 7.0, more preferably 3 to 7. Composition A comprises at least one oxidizing agent and at least one acidic compound and has a pH between 2 and 5, and composition B comprises at least one oxidative dye precursor, optionally at least one coupling agent, optionally at least one direct dye, at least one COreleasing compound and has a pH between 8 and 11.

A method levels hair color, especially lighter colored hair or including lightened streaks or bleached streaks or bleached as a whole and after certain period of time contrast&#x2014;difference in color&#x2014;between the re-growth and formerly lightened parts is clearly visible. The method comprises at least two parts wherein one part being the part not closer to scalp which is artificially color changed to a lighter color by means of lightening and/or coloring and/or bleaching than the other part closer to scalp which is preferably undamaged and has its natural color, wherein hair is optionally shampooed and optionally towel dried and the part directly at the scalp, preferably undamaged and preferably has its natural color, is applied a composition resulting from mixing two compositions, A and B, prior to application.

Method for levelling hair colour

A composition and method oxidative colours hair based on at least one oxidative dye precursor and comprises one or more surfactants and has a pH below or equal to 7.0 after mixing with a composition comprising at least one oxidizing agent wherein the composition is applied onto hair as foam from a non-aerosol foamer vessel.

The present invention relates to a method of leveling color of hair comprising applying to the hair a composition resulting from mixing two compositions, A and B, prior to application, wherein composition A is an aqueous composition and comprises at least one oxidizing agent and has an acidic pH, and a composition B is a substantially anhydrous composition and comprises at least one compound with bleaching effect and has a pH between 8 and 12, wherein the application processed for up to 10 min at a temperature between 20 and 45&#xb0; C. before rinsing and optionally drying steps.

The present invention relates to a process for oxidative coloring keratin fibers especially human hair wherein dyeing compositions are thickened with a selected thickener. The objective of the present invention is a process for oxidative coloring hair wherein compositions A and B are mixed wherein composition A comprises at least one oxidative dye precursor and optionally at least one coupling agent and optionally at least one direct dye in a cosmetically acceptable medium and composition B comprises at least one oxidizing agent in a cosmetically acceptable medium, and applied onto hair and processed for 5 to 45 min at a temperature range of 20 to 45&#xb0; C. and rinsed off from hair, wherein at least one of the two compositions A and B comprises a thickening polyurethane polymer.

Process for oxidative colouring keratin fibres

The present invention concerns a process for oxidative coloring keratin fibers especially human hair wherein a pretreatment is applied onto hair prior to application of oxidative coloring agent. Accordingly, present invention is a process for oxidative dyeing of keratin fibers especially human hair wherein an aqueous composition comprising at least one inorganic salt catalyzing and/or effecting the oxidative color development reaction from oxidative dye precursors is applied onto wet or dry hair and optionally rinsed off, and subsequently an aqueous composition comprising at least one oxidative dye precursor, optionally at least one coupling agent and at least one oxidizing agent is applied onto hair and after processing of 5 to 45 min with or without use of heat, preferably at a temperature range between 20 and 45&#xb0; C., rinsed off from hair.
