[0279] 2 g of each of the mousses was applied to wet locks per half head. This application is carried out on 6 heads for each of the compositions.

[0280] The qualities of use on application and the cosmetic properties conferred on the hair after blow-drying were then evaluated. It emerges therefrom: [0281] that, on application, greater texturization is obtained with composition G according to the invention, and [0282] that, after blow-drying, the hair treated with composition G according to the invention exhibits greater texturization and greater mass.
