Kérastase Résistance Ciment Thermique is a heat-activated blow dry primer designed to protect and strengthen weakened or damaged hair during heat styling. This leave-in treatment infuses each strand with pro-keratin and ceramides to rebuild hair fibers from within, restoring resilience and significantly reducing breakage.

The unique Vita-Ciment Topseal technology forms a protective barrier around the hair shaft, shielding it from heat damage during blow drying and other heat styling up to 450°F (230°C). The formula enhances manageability and smoothness, delivering a flawless, salon-quality finish with every use.

To use, apply a walnut-sized amount to clean, towel-dried hair focusing on mid-lengths and ends, massage in and comb through for even distribution, then proceed with blow drying as usual. No rinsing required. Suitable for all hair types, including chemically-treated hair.
