A hair fiber treating method not containing a fixing step, comprising, applying to the hair fibers at least one reducing composition, free of ceramide, comprising at least one reducing agent; and raising the temperature of the hair fibers using a heating iron at temperature of at least 60&#xb0; C., wherein the temperature of the hair fibers are raised before or after the hair fibers are optionally rinsed.

Method for treating hair fibers

A hair fiber treating method not containing a fixing step, comprising, applying to the hair fibers at least one reducing composition, free of ceramide, comprising at least one reducing agent; and raising the temperature of the hair fibers using a heating iron at temperature of at least 60&#xb0; C., wherein the temperature of the hair fibers are raised before or after the hair fiber are optionally rinsed.

The present disclosure relates to a hair treatment process that comprises applying to the hair a composition comprising at least one ceramide compound in a cosmetically acceptable medium and applying an iron to the hair wherein the iron temperature is at least 60&#xb0; C. and raises the temperature of the hair. The process may be used for smoothing the hair.

Hair treatment process for smoothing the hair

An improvement of a process for permanently reshaping keratin fibres, comprising the application to the keratin fibres, before the reducing operation and/or after the fixing operation, of a pre-treatment and/or post-treatment cosmetic composition comprising, in a cosmetically acceptable vehicle, at least one aminosilicone microemulsion, the number-average primary size of the particles in the at least one microemulsion ranging from 3 to 70 nm.

Process for permanently reshaping the hair using aminosilicones

The present disclosure relates to methods for treating hair fibers, wherein the hair fibers are not fixed with an oxidizing composition, comprising the following steps:

The present disclosure relates to a composition for permanently reshaping keratin fibers, such as the hair, comprising ammonium bicarbonate and at least one other alkaline agent chosen from aqueous ammonia and ammonium salts other than ammonium bicarbonate, with an ammonium molar concentration ratio of greater than 2.1, at least one non-cyclic cationic polymer, and at least one reducing agent, wherein, when aqueous ammonia is present, it is present in an amount of less than 3% by weight. Also disclosed herein is permanent-reshaping process comprising the application of this reducing composition in a first stage, followed, after a leave-in time, by the application of a fixing composition and rinsing of the keratin fibers thus treated. The present disclosure further relates to a multi-compartment device or kit comprising this reducing composition.

Reducing composition for permanently reshaping keratin fibers and permanent-reshaping process

A process for permanently reshaping keratin fibers, comprising the application to the keratin fibers, before reducing and/or after the fixing, of a pre-treatment and/or post-treatment cosmetic composition comprising, in a cosmetically acceptable medium, at least one aminosilicone, as defined herein, in non-microemulsified form.

Process for permanently reshaping the hair using particular aminosilicones

A novel cosmetic composition comprising, in a cosmetically acceptable medium, at least one aminosilicone of as defined herein having, for example, a contact angle ranging from 90&#xb0; to 180&#xb0; and at least one thickener, being able to afford at least one improved cosmetic property (such as lightness, disentangling, volume and sheen) and/or at least one of long-lasting and remanent effects, as well as uses of the composition, such as for washing and/or conditioning keratin materials such as the hair or the skin.

Cosmetic compositions containing a particular aminosilicone and a thickener, and uses thereof

A two-stage treatment process suitable for the permanent deformation and/or shaping of keratinous substances and, in particular, the hair includes the application of a reducing composition containing, in addition to a reducing agent, an organic absorbing agent followed, after an optional rinsing, by the application of a neutralizing composition and by the rinsing of the keratinous substances thus treated.

Process for the permanent deformation of keratinous substances employing an organic absorbing agent

The use, as a pre- or post-treatment of a process for bleaching keratin fibres, such as human hair, of a composition comprising at least one particular aminosilicone as defined herein. Processes for bleaching keratin fibres, such as hair, comprising a pre- or post-treatment with a composition comprising at least one particular aminosilicone as defined herein.

Use of particular aminosilicones as a pre-or post-treatment of processes for bleaching keratin fibres

A pre- or post-treatment composition for the process for bleaching human keratin fibers, such as hair, comprising at least one particular aminosilicone as well as processes for bleaching human keratin fibers, such as hair, comprising a pre- or post-treatment with a composition comprising at least one particular aminosilicone.

Use of particular aminosilicones as a pre- or post-treatment of processes for bleaching keratin fibers

A process for permanently reshaping keratin fibres, comprising the application to the keratin fibres, before reducing and/or after fixing, of a pre-treatment and/or post-treatment cosmetic composition comprising, in a cosmetically acceptable medium, at least one aminosilicone comprising at least one aminoethylimino(C-C)alkyl group.
