Kérastase Hair Styling Mousse 150ml

Fine, limp hair rarely holds volume for long, no matter how much product gets piled on. This kerastase mousse bouffante was built specifically to fix that, delivering strong, flexible hold that thickens hair from root to tip without weighing it down.

This kerastase mousse bouffante combines micronized polymers with xylose and vitamin E in a lightweight, buildable formula. The polymers create a fine, resistant mesh that adheres to each hair fiber for maximum hold with flexible movement, while xylose adds heat protection and vitamin E offers antioxidant support against everyday oxidative damage. The result is a mousse that plumps hair without ever feeling stiff, sticky, or crunchy to the touch.

What Is Kerastase Bouffante Mousse Made Of?

This kerastase bouffante mousse relies on a Hair Defense System built around several key technologies working together. Micronized polymers deliver shape memory and strong hold, a UV filter protects against sun exposure, xylose brings thermo-protective properties for heat styling, and a mineral agent adds texture and body with a soft, natural touch.

How to Use Kerastase Mousse Bouffante

1. Shake the can well before each use.
2. Apply two to four pumps to damp, towel-dried hair.
3. Work through hair using your fingertips, focusing on roots for added lift.
4. Distribute evenly from roots to ends for consistent volume.
5. Air-dry or blow-dry with a round brush to maximize fullness.

A Mousse Built for Real, Lasting Volume

This kerastase mousse bouffante is designed to give fine hair genuine structure rather than a temporary, easily-collapsed lift. Because the amount of volume is controlled by how much product you apply, it offers a flexible way to build density gradually, from a subtle boost to a fuller, more dramatic look.

Why Xylose Makes a Difference

Xylose, a plant-derived sugar with natural thermo-protective properties, helps shield hair from the heat of styling tools without adding heaviness. That protection matters for anyone who regularly blow-dries or uses hot tools to build volume, since repeated heat exposure can otherwise leave already fine hair feeling even more fragile over time.

A Styling Product That Respects Hair's Natural Movement

Unlike stiffer volumizing products that can leave hair feeling crunchy or immobile, this mousse was engineered to maintain flexible movement even at a strong hold level. That balance means hair keeps its natural bounce and softness while still holding the fuller shape the mousse was designed to create.

Suits Humid Climates as Well as Fine Hair

Because the formula includes humidity resistance alongside its volumizing technology, it holds up well in hot, humid weather where fine hair often falls flat fastest. That combination of lift and lasting hold makes it a practical everyday pick for climates where volume tends to disappear within hours of styling.

Pairing This Mousse With the Rest of Your Routine

For an even fuller result, this mousse works well layered with other Kerastase volumizing products, such as a root-lifting spray or a leave-in thickening treatment. Building volume in stages, starting with damp hair and reinforcing it through the drying and styling process, tends to give more lasting results than relying on a single product alone.
