The present invention relates to a composition for washing keratinous materials, in particular hair, which comprises, in a cosmetically acceptable medium, particles essentially consisting of aluminium oxide and having a mean primary size in numerical terms of less than 200 nm, at least one conditioning agent chosen from cationic surfactants, cationic polymers, silicones, vegetable oils, ceramides, anionic polymers, amphoteric polymers and mixtures thereof, and at least one detergent surfactant, these compositions not simultaneously containing an anionic surfactant and an amphoteric or nonionic surfactant. The invention also relates to a method for the cosmetic treatment of keratinous fibres, and a use of the composition according to the invention as a− shampoo.
