This heat-activated non-aerosol styling foam creates weightless body & fullness for fine, limp hair. This weightless foam deposits hydrolyzed oat proteins onto the hair surface to increase the individual strand diameter or each hair whilst volumising silicones create slip & protects from heat damage which can cause further hair thinning & weakness. Hair looks thicker & fuller whilst remaining soft & full of volume. Joico hold factor 4. Formerly known as Joico Body Luxe Design Foam.
