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.

10/10
I have fine,thin,straight,long dark blonde hair and this does miracles for it.. I tried quite a few heat protection spays,serums, creams and what not by the moment this is my absolute favourite, makes my hair so smooth and silky its unbelievable. Previously tried the resistance spray but wasn't too happy with it so if you are wondering between them like I was this is your match.

Amazing!
I’ve been using this product for some time after seeing my hairdresser apply it whilst wet. My hair has never felt so good since using Kerastase products. I have long, thick, coloured hair and works a treat for me. Defo worth it!

Sleek & smooth
I’ve tried many different heat protection products, but this is one of the best, recommended to me by my hairdresser. It makes my hair smooth and silky and so much easier to blow dry, with no tangles. My hair is always affected by any humidity in the air, but when I use this it stays straight or wavy without any risk of frizz. It also smells great.

LOVE this product!
As a hairdresser I only want the best for my hair, this product is amazing! This range smells lush, it tamed my thick, frizzy, damaged hair, my hair was super sleek and glossy after straightening it (which I struggle to get) and it protects your hair up to 230°!

Heat protection
First time using this range after trying various Kerastase ranges. I think this suits my hair best. I've long thick hair in good condition and this does what it's supposed to do. It smells nice too. I intend to buy the rest of this range
