The present invention relates to a process for coloring keratin fibers, preferably hair, comprising the steps of: (i) applying onto the keratin fibers a composition comprising (a) at least one compound chosen from alkylaminosulfonic acids and those of the formula (I) and (II), (b) at least one direct dye, and (c) at least one alkaline agent; (ii) heating the keratin fibers; and (iii) optionally rinsing and/or drying the keratin fibers. The present invention can provide superior coloring efficiency, such as color intensity and color lastingness.

Process and composition for coloring keratin fibers

The present invention relates to a composition for dyeing and/or bleaching human keratin fibers, such as the hair, comprising: a) at 0.15% of at least one neutralized fatty acid, please confirm the minimum amount of fatty acid salt in the ready to use composition b) at least one non ionic surfactant, c) at least one non associative polymer chosen from amphoteric polymers, cationic polymers and mixture thereof, d) at least 10% by weight relative to the total weight of the composition, of at least one fatty substance other than fatty acids, e) at least one oxidizing agent, and f) optionally at least one oxidation dye precursor and/or at least one direct dye. The invention also relates to a method for treating human keratin fibres using this composition.

Composition for treating keratin fibers comprising an amphoteric or cationic polymer and neutralized fatty acid

The present invention relates to a composition comprising one or more cationic surfactants, one or more amphoteric or zwitterionic surfactants, one or more silicones, one or more cationic polymers, one or more fatty alcohols and one or more clays. The invention also relates to a cosmetic process for washing keratin fibres using this composition. Finally, the invention relates to the use of such a composition for washing keratin fibres.

Cosmetic composition comprising a particular combination of surfactants, a silicone, a cationic polymer, a fatty alcohol and a clay

The present invention relates to a cosmetic composition comprising one or more particular non-amino polyalkylsiloxanes comprising at least one fatty chain, one or more oxyethylenated polymers and one or more fatty alcohols. The invention also relates to a cosmetic treatment process of keratin materials, and particularly a method for conditioning keratin fibres, and in particular human keratin fibres, using this composition.

Cosmetic composition comprising non-amino polyalkylsiloxanes, oxyethylenated polymers and fatty alcohols

Composition for caring for keratin fibers and use thereof for cleansing and conditioning the keratin fibers, especially the hair, which includes A) a combination of an anionic surfactant and an amphoteric surfactant; B) at least one cationic polymer with a charge density greater than 4 meq/g; C) at least one aminated silicone; and D) at least one insoluble, non-aminated silicone.

Composition for caring for keratin fibers and use thereof for cleansing and conditioning the keratin fibers

The present invention relates to a multi-compartment device or kit for dyeing keratinous fibers, in particular human keratinous fibers, such as the hair, comprising a first compartment including a dyeing composition (A) comprising one or more oxidation dyes and one or more alkaline agents and a second compartment including a composition (B) comprising one or more oxidizing agents; the said device also comprising one or more self-foaming agents having a boiling point of at least 1&#xb0; C. present in at least one of the compositions (A) and/or (B). The invention also relates to a ready-for-use self-foaming dyeing composition and to a method for dyeing keratinous fibers employing this composition.

Device for self-foaming oxidation dyeing, ready-for-use self-foaming composition and method for dyeing keratinous fibres

A process for permanently reshaping keratin fibers is disclosed. The process may comprise a) placing the keratin fibers under mechanical tension by rolling keratin fibers on a tensioning device so as to form curls, b) applying a reducing composition to the keratin fibers, c) individually covering each tensioning device rolled with keratin fibers with a cover comprising at least one heat-insulating material, so as to form at least one closed space above the keratin fibers, d) heating the keratin fibers at a constant temperature, and e) entrapping heat and condensation from the heating of the keratin fibers within the closed space so as to maintain the closed space at a substantially uniform temperature throughout the closed space. The tensioning device and/or the cover may further include at least one heat source as part of the tensioning device and/or the cover.

Permanent reshaping process using a heating mechanical tensioning device

Provided is a process for permanently reshaping keratin fibers comprising: a) placing the keratin fibers under mechanical tension by rolling keratin fibers on a tensioning device so as to form curls, b) applying a reducing composition to the keratin fibers, c) individually covering each tensioning device rolled with keratin fibers with a cover comprising at least one heat-insulating material so as to form at least one closed space above the keratin fibers, and e) heating the keratin fibers at a constant temperature ranging from 45 to 250&#xb0; C., for a period of time ranging from 1 minute to 2 hours, wherein at least one of the tensioning device and the cover comprising at least one heat-insulating material further includes at least one heat source. Also provided is a kit for permanently reshaping keratin fibers.

The present invention relates to a hair coloring composition containing at least one natural dye, in particular at least one orcein, and at least one particular organic solvent. The invention also relates to a hair coloring method that comprises applying on the fibers a composition containing one or more natural dyes for a duration sufficiently long for obtaining the desired color. The invention thus provides colorings that respect the nature of the hair while offering strong, low-selectivity and resistant nuances.
