I like this product but I don't love it. I think it is protective but it seems to weigh my hair down. It's pretty limp when I use it. I've tried varying the amount and it doesn't seem to matter.

A Game-Changer for Heat Styling!
I absolutely love the Defense Thermique Heat Protecting Spray! As someone who uses heat tools regularly, I’ve tried countless products, but this one truly stands out. It’s lightweight, non-greasy, and leaves my hair feeling silky smooth after styling. I’ve noticed a significant difference in the health of my hair—no more dryness or split ends! TI also smells really good! :)

WOWZA!! LOVE the Genesis scent in all products. I spray this into my hand and work through damp hair. The magic happens with a light blow dry, as soon as heat hits then hair turns shiny and silky. My fine hair loves it. I love it.

Overpowering scent
The product gave my hair great texture and shine. But the scent was not for me. Think baby powder and roses. The smell of my hair was so strong/unpleaant it actually woke me up throughout the night. My husband wasn’t a fan either.

Smells awful (like a strong male cologne)
The smell was unpleasant, I felt I had to wash my hair immediately. The smell was totally unlike the non-spray version of this product (Discipline Heat Protecting Leave-In Treatment For Frizzy Hair), which I use all the time.

Must have for my hair routine
This is the product which I got introduced to in 2020 and since then there is nothing better for me than this Curvy, wavy or straight - it will help with volume and signs of damage. I also like the light texture (good for my fine hair) and the scent.

Beware of softness

Careful with spraying on the floor as the tiles will become super sleek and you can fall
Both my daughter and I were losing a ton of hair and by using the set of shampoo conditioner scalp treatment and spray leave in we recovered and our hair is growing again

Pointes plus sèches qu’avant de l’utiliser.
Ce produit assèche mes cheveux. J’ai les pointes séches d’habitude mais ce produit les assèche encore plus. Je pense qu’en séchant, le produit laisse de résidu et laisse les pointes extrêmement secs. Trop de silicone dans le produit peut-être. En plus l’odeur est citrique mais un peu trop fort pour mon gout. Je préfère toujours le Nectar thermique depuis des années qui est le meilleur!

Do it’s thing!
What I like the most about the heat protectant is that it doesn’t leave my hair oily or with a wet feeling. It’s so lightweight. Love it!

Keeps my hair soft, manageable and frizz free!
I use this product before every blow dry. It detangles instantly and helps my bleached hair areas to look less dry. I love this product!

Best product ever!
I always iron my hair for added style, but it makes my hair dry and prone to breakage. Using Kérastase Défense Thermique Heat Protecting Spray helps a lot in reviving and protecting my hair.

My favorite as a leave in
[This review was collected as part of a promotion.] I have thick unruly hair. I use as a leave when I need to air dry my hair and can then smooth fly always with a boar brush. Great for hot summer hair days

Best heat protectant I have tried!

Great heat protectant. It does not weigh down my fine hair. I love the smell, not overpowering.

Wonderful!!
[This review was collected as part of a promotion.] My hair feels soft and full. So many thermal protectants leave a heavy film but Keratase leaves my hair free to move.

Need a better spray
Fan of the product, but I wish the spray distributed the product more. It seems to only shoot out.

Truly couldn’t get enough of this!
My hair went through it all — bleach, straightening, you name it. I’ve been working on quitting as many processes and bad habits as possible to grow out my hair, and this leave-in has been a game changer. It brings softness and life to my dull, abused strands. Will definitely repurchase!
