Cosmetic treatment process comprises forming a coating on the keratin fibers comprising preparation of an aerogel precursor composition, applying the composition on the fibers, and elimination of the solvent to form an aerogel composition
Cosmetic treatment process comprises forming a coating on the keratin fibers comprising: (1a) preparation of an aerogel precursor composition comprising (a) at least one organic solvent comprising e.g. acetone, (b) at least one precursor compound containing e.g. at least one atom comprising silicon, titanium, aluminum and zirconium； (2a) applying, on the keratin fibers, the aerogel precursor composition； and (3a) elimination of the solvent to form an aerogel composition having a bulk density of = 0.35 g/cm 3>；. Cosmetic treatment process comprises forming a coating on the keratin fibers comprising: (1a) preparation of an aerogel precursor composition comprising (a) at least one organic solvent comprising acetone, 1-4C alcohols, 1-6C alkanes, and/or optionally perfluorinated 1-4C ethers, (b) at least one precursor compound containing at least one atom comprising silicon, titanium, aluminum and zirconium, at least one hydroxy or alkoxy function directly attached to the atom comprising silicon, titanium, aluminum and zirconium by an oxygen atom, and at least one organic group directly attached to the atom comprising silicon, titanium, aluminum and zirconium by a carbon atom； (2a) applying, on the keratin fibers, the aerogel precursor composition； and (3a) elimination of the solvent to form an aerogel composition having a bulk density of = 0.35 g/cm 3>；.La présente invention concerne un procédé de traitement cosmétique comprenant la formation d'un revêtement sur les fibres kératiniques caractérisé en ce qu'il comprend : 1) la préparation d'une composition précurseur d'aérogel comprenant : - au moins un solvant organique choisi parmi l'acétone, les alcools en C -C , les alcanes en C -C et leurs mélanges et - au moins un composé précurseur qui contient : - au moins un atome choisi parmi le silicium, le titane, l'aluminium et le zirconium, - au moins une fonction hydroxy ou alcoxy directement rattachée à l'atome choisi parmi le silicium, le titane, l'aluminium et le zi
