Problems solved by technology

However, where the hair has been damaged by treatments such as oxidative treatments, such materials may not provide the same benefits in hair conditioning as non-oxidatively treated (untreated) hair

Abstract

The invention provides a method of conditioning hair by application of a conditioning shampoo composition, in which the hair is oxidatively-treated hair and in which the conditioning shampoo composition comprises: i) an aqueous continuous phase including cleansing surfactant, ii) a dispersed phase including emulsified droplets of non-volatile silicone having a mean droplet diameter (D3,2) of 1 micrometre or less, and iii) a solubilised oily liquid conditioning agent for skin and / or hair; in which the oily liquid conditioning agent is solubilised in wormlike micelles in the aqueous continuous phase via the incorporation of at least one inorganic electrolyte and at least one linker molecule which is selected from compounds of general formula R(X)n, in which R is an aryl ring having from 6 to10 carbon atoms or a mono-, di- or trivalent alkyl or hydroxyalkyl chain having from 3 to 14 carbon atoms; n is 1 to 3 and each X is independently selected from -OH, -COOH and -COO-M+ groups, where Mis an alkali metal, ammonium or alkanolammonium cation; and in which the level of solubilised oily liquid conditioning agent in the conditioning shampoo composition ranges from 0.45 to 3% by weight based on the total weight of the conditioning shampoo composition. The method according to the invention provides for the enhanced conditioning of oxidatively-treated hair compared to virgin hair.

Description

technical field [0001] The present invention relates to a method of conditioning hair. More particularly, the present invention relates to a method of selectively conditioning damaged hair. Background technique [0002] The purpose of bleaching is to remove or lighten natural hair color through the reaction of oxidizing agents with melanin. Examples of oxidizing agents which can be used are hydrogen peroxide, potassium, sodium or ammonium salts of perboric acid, percarbonic acid, persulfuric acid and percarbamide, and mixtures thereof. [0003] Bleach can also be used during oxidative dyeing treatments. Oxidative (or "permanent") dye compositions contain "precursor dyes," which are small molecules capable of diffusing into the hair. These molecules mainly belong to three classes of aromatic compounds: diamines, aminophenols, and phenols. They are small enough to diffuse in the hair shaft, where once activated by an oxidizing agent such as hydrogen peroxide, they further ...
