Kerastase has the best heat protection products, but this is unacceptable. It leaves a heavy feeling on the hair, you feel it greasy and I don't think it has protected the hair from heat, I find damage in my hair. Do not prefer it.

Personally, it doesn't smell as many comments say, but it definitely doesn't do what it promises... I have wavy hair with thin strands... I tried once to blow dry it as recommended, but there was absolutely no difference and my hair felt a bit heavier. I thought, let's try it without blow drying... Even worse, it left my hair completely greasy right after showering... It's definitely not worth the money in any case. The 2 stars are only because it doesn't smell like other sprays

My hair is thin, oily, and curly with many frizz. I have the whole range, shampoo, mask, and spray, and I apply the mask for at least 15 minutes after blow-drying my hair. I rinse, blow-dry again, and apply the spray for drying. The smell is divine!!! Indeed, during drying, the hair does not have a natural texture. They don't stick exactly, as I read in many comments, but they do weigh down a bit. The brush almost struggles to go through. However! The result is as it says. Until the next wash, they don't get curly, they don't frizz. Without many brush strokes, they straighten immediately! Especially if you also use a straightening iron, they don't break at all! Just as I wrote, the hair becomes a little harder and doesn't fall lightly on the shoulders. It doesn't bother me at all! I recommend it and will buy it again!

Very mediocre product, I mainly use it for heat protection, otherwise I don't see any difference in my hair, neither in hold nor in frizz. It's okay, let's not expect miracles. It smells nice.

I wonder about the comments that it smells and sticks to the hair.
They probably confused it with another product, this one smells amazing, so much so that it uplifts your mood, and it definitely doesn't stick to the hair. I have fine hair with oily roots and I didn't feel any heaviness using the spray. It's really good and helps with frizz for 2-3 days until the next wash. Luckily, I didn't rely on the negative comments before choosing to buy it.

Very bad product in my opinion. I have thick, wavy hair prone to frizz. This specific product made my hair greasy no matter how I used it, it would stick, it didn't enhance the waves in my hair, it didn't help with frizz at all, it did nothing, and personally, the scent made me nauseous. If you desire a "licked by a cow" look, then don't go anywhere else, you found your product. For the rest, stay away. I also used the shampoo and conditioner from the same line and it made my hair straw-like. Also, both of them smell, especially the conditioner.

It is amazing. Indeed, the hair does not frizz. It smells perfect and its duration is satisfactory. I recommend it!

Useless product, it does nothing for frizz and overall, it also has a terrible scent. Waste of money

I have thin and oily hair. It only needs a maximum of 3-4 sprays on the entire head to prevent the hair from getting greasy. Otherwise, it is excellent

Thick hair prone to frizz, made my hair greasy without reducing frizz.. what can I say..
