This ultra-dense mousse cream causes the hair to swell with heat, creating a light, sculpted, voluminous style. The structuring polymers in the formula provide excellent hold to facilitate working with a round brush, while the foam adds moisture, softness, shine, and natural smoothness to the hair - without a cardboard effect. Ideal for all hair types and textures, especially fine hair. Like all Bumble and bumble products, this mousse is also cruelty-free.
