Activated by heat, the Kérastase Resistance Ciment Thermique a resurfacing blow-dry milk that protects and conditions fine, breakage-prone hair. Formulated with the brand’s patented Vita-Ciment® Topseal, the treatment provides a protective top coat over the lengths, defending them from visible brittleness and split ends. Thermo-seal glazing smooths the hair and adds shine, while lending heat protection against styling tools and sun rays. Applied at the end of your hair routine, the treatment's lightweight, conditioning consistency leaves the hair feeling soft with a silk-like shine, ready for subsequent styling.
