Abstract: The present invention discloses methods and kit-of-parts for treating keratinous fibres prior to dyeing to control and modulate dye uptake into the fibre. Organic solvents having log P of from ?4.0 to ?0.5 or from 0.5 to 4.0 are used to manufacture pre-treatment composition to be applied to the hair. When the hair is pre-treated with at least one organic solvent having a log P of from 0.5 to 4.0 the dye penetration into the keratinous fibres is enhanced, while pre-treating the hair with at least one organic solvent having a log P of from ?4.0 to ?0.5 reduces the dye uptake. One or more compositions to pre-treat the keratinous fibres can be effortlessly applied on different zones of the hair and can be left in place or removed prior the application of the dyeing composition.

Abstract: The present invention relates to the field of hair care. More specifically, the present invention relates to the conditioning of hair after it has been oxidized in a coloring, bleaching or perming treatment. Superior conditioning is obtained by providing a cationic polymer to the hair while it is subjected to the oxidizing treatment, and then the oxidized hair is subjected to a conditioning treatment with a composition comprising a functionalized silicone.

Abstract: The object of the present patent application are agents for the oxidative coloring of keratin fibers, particularly hair, based on a developer substance-coupler substance combination, characterized in that they contain at least one meta-aminophenol derivative of general formula (I) wherein R1 denotes hydrogen, a C1-C6 alkyl group, a C2-C4 hydroxyalkyl group, a C2-C4 dihydroxyalkyl group, a C1-C4 alkoxy group or a halogen atom; and R2 denotes hydrogen, a hydroxy group, a carboxylic group, an aminocarbonyl group or a hydroxymethyl group.

Abstract: The present invention relates to a method of hair coloring and bleaching compositions providing a composition comprising i) at least one source of peroxymonocarbonate ions, ii) at least one alkalizing agent, preferably a source of ammonium ions, and iii) at least one radical scavenger, wherein said composition has a pH of up to 9.5, and applying the composition to the hair and retaining on the hair for a period of less than 20 minutes, which provide a high level of lift and lightening and the required dye deposition and grey coverage whilst reducing the concentration of peroxide, the ammonia odor and reducing the hair fiber damage.

Abstract: The invention relates to a hair treatment applicator for applying a hair treatment product composition to a user's hair by passing the applicator through the hair in a predetermined direction, where the applicator comprises a handle and a head connected to the handle, where the head includes a body having a base and a retaining structure, the retaining structure comprising a pair of opposed blades extending downwardly from the base and proximate the edges of the base, the pair of opposed blades being disposed coincident with the direction of use and the opposed blades defining a retaining volume adapted to receive the hair treatment product composition.

Abstract: The present invention relates to an oxidative hair colouring and bleaching composition comprising an oxidizing agent, a source of carbonate ions, an alkalising agent, and preformed dyes, utilised at pH 9.5 and below which improved colour delivery, intensity and vibrancy, which are compatible with current dyes and dye precursor systems. Moreover, the compositions of the present invention also exhibit low odour and deliver a high level of lift and lightening equal to the currently utilised ammonia/peroxide systems, whilst reducing the concentration of peroxide and reducing the hair fibre damage.

Abstract: Colorant for keratin fibers containing cationic indazoline thiazolazo dyes of the general formula (I).

Abstract: Tricyclic 5-6-5 heteroaromatic keratin dyeing compounds having two heteroatoms. Compositions for the oxidative dyeing of keratin fibers, comprising a medium suitable for dyeing and one or more tricyclic 5-6-5 heteroaromatic keratin dyeing compounds having two heteroatoms.
