What Is It?

KERASTASE Genesis Homme Spray De Force Épaississant 150ml is the lightweight thickening styling spray within the Genesis Homme collection.

Its main purpose is cosmetic thickness.

When hair becomes finer or less dense, the individual fibres can lack substance and the overall hairstyle can appear flatter. Spray De Force Épaississant helps thicken the feel and appearance of the hair fibre, giving the sensation of fuller, stronger hair.

Think of it as:

Thicken → Add Body → Create Volume → Light Hold → Fuller-Looking Hair

This makes it particularly useful for men who want their hair to look thicker immediately without using a heavy wax, clay or strong-hold styling product.

Spray De Force vs Cire D'Épaisseur Texturisante

These two Genesis Homme products work particularly well together, but they have different jobs.

Spray De Force Épaississant → Lightweight thickening spray used throughout the hair to increase body, volume and the sensation of density.

Cire D'Épaisseur Texturisante → Thickening molding clay used for styling, definition, texture and a matte finish.

So:

Need overall thickness & volume → Spray De Force

Need texture, definition & matte styling → Cire D'Épaisseur

Want maximum fuller-looking styling → Use both
