KÉRASTASE Mousse Bouffante Volumising Mousse — 250ml Lightweight, Heat-Protecting Strong Hold

KÉRASTASE Mousse Bouffante is a lightweight, buildable volumising mousse that gives fine or limp hair long-lasting body, flexible hold, humidity resistance and heat protection.

Made to lift hair from roots to ends without stiffness, this mousse combines Xyloses and vitamins in a featherweight formula that thickens strands while preserving movement. It works as a daily styling step or a prep product before heat tools, and pairs well with nourishing KÉRASTASE treatments to maintain shine and manageability between styling sessions.

How does this mousse add long-lasting volume without weighing hair down?

The formula uses plumping agents to expand fiber diameter while delivering a flexible hold, so hair looks fuller but remains soft to the touch. Its lightweight base prevents heavy buildup so repeated use won't leave hair flattened.

• Xyloses and vitamins to thicken and strengthen individual strands
• Featherweight texture for lift at the roots without residue
• Humidity resistance to preserve shape in damp conditions

Can I use Mousse Bouffante before heat styling and will it protect hair?

Yes — the mousse provides heat protection suitable for styling tools while helping maintain volume during blow-drying or hot tools. It’s formulated to shield strands from routine heat exposure while supporting flexible, bouncy results.

• Heat protection included for safer use with dryers and irons
• Supports blow-dry techniques that build root lift and body
• Doesn’t stiffen hair, allowing natural-looking movement after styling

How do I apply the mousse for the best results?

Dispense 2–4 pumps into damp, towel-dried hair and distribute evenly from roots to ends using fingertips. Define shape as desired, then air-dry for natural volume or blow-dry with a round brush for enhanced lift and texture.

• 2–4 pumps for medium volume; adjust amount for finer or thicker hair
• Work through hair focusing on roots to maximize lift
• Air-dry for soft fullness or heat-style for structured volume

How does this product fit into a larger hair-care routine?

Mousse Bouffante is designed to complement KÉRASTASE treatments and cleansing products: use a hydrating shampoo and conditioner before styling and apply a finishing oil or serum when extra shine or nourishment is needed. Regularly alternating styling with restorative treatments helps preserve hair health while maintaining volume.

• Pairs well with Le Bain Shampoo and Le Fondant Conditioner
• Combine with Elixir Ultime products for added shine and nourishment
• Use restorative masks between styling sessions to maintain fiber integrity

Who is this for: Anyone with fine, limp or soft hair seeking a controlled yet flexible increase in body and texture. It’s particularly useful for those who want buildable volume, humidity resistance and light heat protection without a heavy or crunchy finish. Ideal for daily styling, special-occasion blowouts, or to prep hair before thermal tools while keeping movement and shine.
