KÉRASTASE Mousse Bouffante Volumising Mousse 150 ml — Lightweight Lift, Heat Protection

KÉRASTASE Mousse Bouffante is a lightweight volumising mousse that builds long-lasting body and flexible hold while protecting hair from heat.

This 150 ml mousse is formulated to give fine or limp hair visible lift from roots to ends without stiffness or weight. Enriched with xyloses and vitamins, the texture-plumping formula thickens strands and provides humidity resistance so volume lasts through daily styling. The mousse works as a foundation for air-dried or heat-styled looks and pairs well with KÉRASTASE treatments for added nourishment and shine.

How will this mousse change my daily styling routine?

Use the mousse as a quick volume boost on damp, towel-dried hair to speed up styling and create a fuller base for most hair looks. Its flexible hold lets hair move naturally while keeping shape, so you can tousle, blow-dry, or diffuse without crunchy residue. The formula layers under finishing products and tools, giving predictable lift without weighing strands down.

• Apply 2–4 pumps to damp hair, working evenly from roots to ends.
• Style by air-drying for soft volume or blow-dry for amplified lift.
• Combines with creams, serums or sprays for texture or shine without losing body.

What does it contain and how does that affect hair appearance?

The mousse features xyloses and vitamins that act to plump the hair fibre, creating thicker-looking strands and fuller volume. Humidity resistance helps control frizz and keeps shape in changing weather, and the lightweight base ensures hair stays bouncy rather than flat. There is also heat protection to safeguard hair during blow-drying and styling tool use.

• Xyloses and vitamins: add visible thickness to the fibre for fuller-looking hair.
• Heat protection: reduces styling damage risk when using hot tools.
• Humidity-resistant finish: helps maintain volume and control frizz.

How much should I use and will it feel heavy or sticky?

The amount controls the level of lift — start with 2 pumps for subtle body and increase to 4 pumps for stronger volume. The formula is designed to be lightweight, so hair stays flexible and natural-looking without a sticky or stiff finish. Work the mousse through hair with fingertips to distribute evenly, focusing on the roots for maximum lift.

• 2 pumps: light volume and natural movement.
• 3 pumps: medium fullness, suitable for most styles.
• 4 pumps: maximum lift for finer hair or voluminous styles.

Can I use it with other KÉRASTASE products?

Yes — Mousse Bouffante pairs smoothly with cleansing and conditioning ranges to improve overall results. Use with Le Bain Shampoo and Le Fondant Conditioner for a clean, detangled base, and follow with Elixir Ultime treatments between styling sessions for extra nourishment and shine. Layering compatible products helps extend style longevity while maintaining hair health.

• Pair with Le Bain Shampoo and Le Fondant Conditioner for optimal texture.
• Add Elixir Ultime between styles for enhanced nourishment and gloss.
• Works under finishing sprays or texturizers without losing volume.

Who is this for: KÉRASTASE Mousse Bouffante suits anyone with fine, limp or flat hair seeking painless, buildable volume and a flexible hold. It’s ideal for users who want natural movement with humidity resistance and heat protection, whether you prefer air-dried waves or blow-dried, high-volume styles. Recommended for at-home daily styling and as a professional backstage or salon-ready styling product.
