Lovely product
This is a very good product to protect your hair against and heat damage. The bottle is very cute and since it spray kind so it’s easy to use . Doesn’t leave any residue in my hair and just blends into my hair while blow drying it. Helped tame my frizz too and it has one of the best scent.

Absolutely fabulous
Although I have used this product only a couple of times I am thrilled with it. Heat protection is vital when your hair has become brittle. Using this with my usual quick blow dry has left my hair soft and manageable whilst keeping in perfectly styled between washes.

Kerastase Genesis Defense Thermique
Kerastase Genesis Defense Thermique a fantastic heat protection cream, it smells lovely and the smell lingers all day on your hair which is just great, it thins out nicely when rubbed between your hands so not thick and heavy like some others I have used in the past, after drying my hair felt stronger, smelt great and looked fantastic what can I say this product is nothing short of pure genius! Highly recommend and will be buying again. 10/10

Genesis Anti hair-fall care Défense Thermique
I finger-dried my hair today after using the spray and I've not even used a brush yet. My hair is so soft and shiny, and not at all flyaway. As this was a first time use, I can't comment on hair loss prevention at this time, but I know that using it is protecting my hair from any possible heat damage.

Definitely recommend!
This styling cream is essential for this collection. I have so many styling products so was skeptical about trying another but this is my new favourite. It has heat protection and leaves my hair super straight. I used this for the first time before an important career dinner and it did not let me down. It’s so lightweight. Also, the entire collection is hands down the best smelling kerastase collection!

Fab Results
Thanks to the Hair Community Team I have been lucky enough to test Genesis Defense Thermique. The instructions were a tad hard to read print very small, you only need to apply a little bit onto damp hair. I noticed straight away upon application that is smells devine and its not greasy. After drying my hair the first time it did look a little shiner but after the second application defintelty noticed a difference. My hairs feels and looks softer, shiner and tangle free and as its not greasy your hair feels lighter.

Blow dry best mate!
I have already used this product 3 times so it’s early but I can see that helps to protect my hair from damage and is not a greasy product. After blow dry my hair looks glossy and easy to brush. I have thin and weak hair so I will continue using this line, I am happy so far!

Great strengthing product
Defense Thermique is great for strengthening hair, a quality and premium product that is easy to apply and with frequent usage appears to build up a resistance and a barrier against weakened and damaged hair
