A method of conditioning hair by applying a conditioning shampoo composition comprising: The hair is oxidatively treated hair, The conditioning shampoo composition comprises: (i) an aqueous continuous phase comprising a cleansing surfactant; (ii) a dispersed phase comprising emulsified droplets of a non-volatile silicone having an average droplet diameter (D3,2) of 1 micrometer or less; (iii) a solubilized oily liquid conditioning agent for skin and / or hair; Including, The oily liquid conditioning agent comprises at least one inorganic electrolyte and a compound of the general formula R(X): ｎ wherein R is an aryl ring having 6 to 10 carbon atoms or a monovalent, divalent or trivalent alkyl or hydroxyalkyl chain having 3 to 14 carbon atoms, n is 1 to 3, and each X is independently selected from -OH, -COOH and -COO － M ＋ group, M is an alkali metal, ammonium, or alkanolammonium cation; the level of solubilized oily liquid conditioning agent in the conditioning shampoo composition is in the range of 0.45 to 3 wt. %, based on the total weight of the conditioning shampoo composition; the oily liquid conditioning agent is a light mineral oil having a kinematic viscosity of 3 to 5 cS (mm 2 .s −1 ) at 40° C.; The method wherein the level of the light mineral oil ranges from 0.5 to 1.5 wt. %, based on the total weight of the conditioning shampoo composition.

2. The method of claim 1 , wherein the oxidatively treated hair is bleached hair.

3. 3. The method of claim 1, wherein R is a phenyl ring or a monovalent, divalent, or trivalent linear alkyl or hydroxyalkyl chain having 3 to 12 carbon atoms.

4. The method of claim 3 , wherein the linker molecule is caprylic acid.

5. 5. The method of claim 4, wherein the level of caprylic acid ranges from 0.05 to 0.15% by weight, based on the total weight of the composition.

6. Use of a conditioning shampoo composition according to any one of claims 1 to 5 for improved conditioning of oxidatively treated hair compared to untreated hair.
