K Première Serum Filler Fondamental

The Kérastase K Première Sérum Filler Fondamental is a lightweight, leave-in repairing hair serum that offers dual action for all types of damaged hair. This anti-frizz serum works to seal and fill hair strands, protecting them from heat styling tools up to 230°C while restoring strength and shine. It’s particularly effective for hair that has absorbed excessive calcium from hard water, which can weaken the hair fiber.
