The subject of the present invention is a process for treating keratin fibers using an anhydrous dye composition comprising at least one compound of azomethine type comprising two pyrazolopyridine units of formula (I) or (II) and an aqueous composition. The invention also relates to a kit comprising an anhydrous dyeing composition and an aqueous composition.

Process for treating keratin fibers using an anhydrous composition comprising a compound of azomethine type comprising two pyrazolopyridine units and an aqueous composition

The present invention relates to an aerosol device comprising a composition for dyeing keratin fibres, comprising at least one aqueous dispersion of particles of hybrid, film-forming, hydrophobic acrylic polymer, at least one silicone compound chosen from linear silicone block copolymers and amino silicones, and at least one pigment. The invention also relates to a dyeing process in which said composition is applied to keratin fibres, the operation optionally being followed by drying. The composition makes it possible to obtain a coloured coating, which is persistent with respect to shampooing operations, leaving the treated fibres individualized, with an improved cosmetic feel.

Aerosol device for pigment dyeing based on a particular acrylic polymer and a silicone compound, dyeing process

The present invention relates to a process for treating keratin fibers, especially human keratin fibers such as the hair, using i) at least one triarylmethane or sulfonophthalein direct dye of formula (I) or (I') as defined below, ii) an alkaline revealer, iii) an eraser at acidic pH. A subject of the invention is also a composition comprising at least one triarylmethane direct dye of formula (I) or (I&#x2032;) as defined below and at least one thickener and/or at least one hydrotropic solvent, and a multi-compartment kit comprising i), ii) and iii) in three separate compartments. The present invention makes it possible in particular to obtain keratin fiber coloring with intense and persistent tints which can be modified, erased and reformed several times without any loss of color.

Process for treating keratin fibers using a halochromic triarylmethane direct dye, an alkaline revealer and then an acidic eraser

Provided herein is a composition for treating keratin fibers that comprises at least one silicone copolymer based on at least one silicone resin and at least one fluid silicone, and at least one liquid volatile linear alkanes. Also provided herein is a method of treating keratin fibers, comprising applying the composition to the keratin fibers.

Cosmetic composition comprising at least one silicone copolymer and at least one liquid volatile linear alkane mixture

The present disclosure relates to a cosmetic composition for treating keratin fibers, for example human keratin fibers such as the hair, comprising, in a cosmetically acceptable medium, at least one organosilicon compound chosen from silanes comprising one, two and three silicon atoms, wherein the at least one organosilicon compound also comprises at least one basic chemical function and at least one group chosen from hydroxyl and hydrolysable groups per molecule; at least one hydrophobic film-forming polymer; at least one pigment; and at least one volatile solvent. The present disclosure also relates to a process for treating keratin fibers, comprising applying to the keratin fibers the compositions according to the present disclosure.

Cosmetic composition comprising at least one organosilicon compound comprising at least one basic function, at least one hydrophobic film-forming polymer, at least one pigment and at least one volatile solvent
