Kérastase Première Sérum Filler Fondamental 90ml

Kérastase Première Sérum Filler Fondamental is a revolutionary leave-in treatment designed to repair and protect all types of damaged hair. This lightweight, balmy serum penetrates deep into the hair fiber to reinforce internal strength while sealing the cuticle to prevent frizz and moisture loss. It’s powered by a dual-action formula: Citric Acid removes calcium buildup from hard water, restoring softness and flexibility, while Glycine repairs and strengthens from within. The serum offers heat protection up to 230°C and delivers 72-hour anti-frizz control, leaving hair up to 3x smoother and 2x softer. Ideal for use before blow-drying or as a finishing touch on dry hair.

How to Use:
