Protect locks from the damaging effects of heat-styling with the Kérastase Extentioniste Thermique; a length-strengthening thermal gel-cream that reinforces tresses from root to tip, preventing tension and split ends.
Infused with the brand’s exclusive Creatine R™ complex combined with Taurine, the leave-in treatment goes to new lengths, working to smooth the hair follicles and provide the ultimate in hair endurance. Creamy and lightweight, it’s designed to gently restore hair and detangle without causing breakage. Ceramides promotes elasticity and moisture retention, aiding in the strengthening of weak, over-processed hair, whilst Maleic Acid helps neutralise pH levels of hair follicles, eliminating dandruff and removing dirt deposits.
Tousle through clean, damp hair before blow-drying, curling or straightening, for enhanced shine and inviolable resilience.
Apply a walnut-sized amount to towel-dried hair. Style using a hairdryer or heat-styling appliance. In case of contact with eyes, rinse them immediately and thoroughly. Leave in, do not rinse.

A constant in my routine
This is one of those products I buy over and over again. My hair is very long and does require more maintenance than most. I use this product before every blow dry on my lengths and it absolutely makes a difference to the overall feel and look of my lengths!
