Couture Styling Mousse Bouffante is a super delicious mousse from Kerastase. This mousse allows you to build up your hairstyle in layers, adding volume and structure over and over again. The mousse provides maximum hold and flexibility, allowing hair to move naturally. It has a UV filter and contains vitamin E, which takes care of and protects against damage. The Kérastase mousse bouffante is a foam for exceptional volume with a natural touch. It gives the hair heat protection, shape retention and noticeably more fullness and grip. The blowing agents isobutane, probane and butane turn the foam into a melting and at the same time fine foam texture.
