Kérastase Resistance Ciment Thermique 150ml is a leave-in, heat-activated blow-dry milk formulated to reinforce and protect weakened, damaged hair. Enriched with Vita-Ciment® to rebuild hair fiber, Ceramides to restore intercellular cement, and Sève de Résurrection for revitalization, it fortifies hair from within. The Glacage Thermo-Seal smooths and adds shine, while offering up to 180°C heat protection. This lightweight formula reduces breakage, accelerates blow-dry time, and leaves hair soft, resilient, and luminous. Ideal for brittle or over-processed hair, it ensures a sleek finish without weighing hair down. Apply to towel-dried hair before styling for optimal results.
