Kérastase Première Sérum Filler Fondamental (90ml)

Kérastase Première Sérum Filler Fondamental (90ml) is a repairing leave-in serum designed for damaged, over-processed, or chemically treated hair. It helps reinforce the hair fiber, reduce breakage, and smooth the surface while restoring softness and shine. It also works to neutralize calcium buildup (from hard water), which can further weaken and dull the hair.

How to use

1. Apply to towel-dried hair after washing and conditioning/masking.
2. Dispense 1–2 pumps (more for longer or thicker hair).
3. Distribute evenly through mid-lengths and ends.
4. Do not rinse out.
5. Blow-dry or style as usual.
