A method for treating keratinous material, in particular human hair, is disclosed. The method comprises applying to the keratinous material a first composition (A) and a second composition (B). The first composition (A) comprises (A1) less than about 10% by weight of water, and (A2) one or more organic C1-C6 alkoxy silanes and/or condensation products thereof. The second composition (B) comprises (B1) water, and (B2) one or more aromatic compounds of a particular formula (AR-I). A multi-component packaging unit (kit-of-parts) comprising the first composition (A) and the second composition (B) is also disclosed.
