REPAIRING SERUM WITH FILLING AND ANTI-FRIZZ EFFECT 90ML
Kerastase Premiere Serum Filler Fondamental is a leave-in serum, designed for all types of damaged hair prone to frizz. With a concentrated yet lightweight formula, this professional serum works from within the hair fiber to repair, fill, and seal the cuticle, leaving hair visibly smoother, stronger, and shielded against external aggressors.
Hair that is overprocessed, frequently colored, bleached, or exposed to hard water becomes porous and absorbs up to 3 times more calcium than healthy hair. This excess weakens internal keratin bonds, leading to fragility, breakage, and a dull appearance. Serum Filler Fondamental penetrates deep into the fiber and reconnects the internal structure, leaving hair soft, smooth, and visibly reinforced.
This professional filling serum is ideal for daily use in an intensive repair routine. It provides heat protection up to 230°C, an anti-frizz shield for 72 hours, and prevents the negative effects of humidity and hard water. Its silky texture absorbs quickly without weighing the hair down, offering a feeling of suppleness and natural shine.
