Kérastase Première Sérum Filler Fondamental
Who It's For
For damaged, brittle, or over-processed hair craving softness, smoothness, and deeper repair. Perfect for colour-treated hair, hard-water buildup, and anyone wanting strong, glossy, beautifully behaved strands.
What It Is
A lightweight, leave-in repairing serum that strengthens the hair fibre from within while smoothing the outside for a soft, polished finish. Powered by Kérastase's calcium-removal and bond-rebuilding technology, this serum restores flexibility, reduces breakage, tames frizz, and keeps hair feeling healthy and touchably smooth — all without weight.
Why You'll Love It
Hair becomes easier to style, less prone to snapping, and instantly more radiant. The kind of product you use once and think, “This is staying in my routine forever.”
How to Use
Apply 2–4 pumps to clean, towel-dried hair. Work through mid-lengths and ends. Do not rinse. Style as usual. Can also be applied to dry hair anytime you need extra smoothness and shine.
When to Use
Use daily for ongoing repair, softness, frizz control, and smoother styling. A perfect primer before blow-drying or air-drying.
Fragrance
A luminous blend of citrus, white florals, and airy musk — fresh, elegant, and quietly addictive.
