Description:

The Kérastase Première Sérum Filler Fondamental is a repairing anti-frizz filler serum for all types of damaged hair. This lightweight Serum works to repel humidity, deeply nourish and lock out frizz. It protects hair against heat tools. Fills fiber surface with matter to recreate softer and smoother hair.

Due to its heightened porosity, processed hair absorbs three times more calcium from water as compared to untreated hair, resulting in calcium overdose, both internally and externally within the hair shaft. The Kérastase Sérum Filler Fondamental Hair Serum provides a dual-action solution: its lightweight, balm-like texture seals the cuticles, safeguarding the hair's surface, while simultaneously replenishing the fibre and reinforcing hair strength. This protects your hair from the damaging effects of calcium found in hard water, as well as from humidity and heat up to 230°C. Say goodbye to damage & frizz as your hair becomes smooth, supple, easy to style and effortlessly manageable.

For even more care for your bleached or damaged hair, combine with the rest of the Première range. Try the maximum power of the layering technique: Start with the pre-shampoo treatment, Kérastase Concentré Décalcifiant Ultra-Réparateur, then without rinsing off the Concentré, use the shampoo, Kérastase Bain Décalcifiant Réparateur on top. Follow with the conditioner or mask before applying Kérastase Sérum Filler Fondamental as a final repair step.
