Method of making a product adhere to a surface, in which a composition is brought into contact with the surface, the composition containing the product incorporated in substantially spherical, multilamellar vesicles, with a diameter of between 0.1 and 100 mum, and including concentric membranes based on at least one surfactant and separated by a solvent medium. Each of the vesicles has an onion-like structure formed of a succession of concentric bi-layers extending from each vesicle center to its periphery, and containing therein at least one cationic agent, resulting in the vesicles carrying a positive overall charge.
