    No thanks

    The hair becomes extremely static and flyaway from this product! The bathroom floor was full of broken hair strands after I blow-dried my hair. Doesn't suit my hair.

      Thank you for your question, and how fun that you like the Kerastase products! 💗 For the best results, you can try applying the hair oil after using the heat protectant, but before you start blow-drying your hair. This way, you get both moisture and reduce static electricity during drying. Remember to only apply a small amount of the oil so you don't weigh down your hair 🤗 Wishing you a wonderful day ahead! 💚

    Awesome but only on wet hair

    Using the rest of the line and loving all the products. This is fantastic for blow-drying in, but don’t use too much. Tried using it on dry hair before I straightened, but it’s way too heavy and my hair didn’t feel clean anymore. So use it on dry hair, but it works so well on damp!

    Love!

    I bought the Genesis discovery set that had this product included. Strong, but nice scent. I spray this on towel-dried hair and of course use other hair products and blow-dry it. It also detangles very well. Hair is much smoother than usual and soft.

    Can I flat iron my hair with this

    Can I flat iron my hair with this product when it’s dried in my hair, or do I also need to use a heat protectant?

    Should it be like this?

    Hey! I bought this a while ago and love it, but when I try to take the product out, it comes out as a hard stream. I don't know if it's supposed to be like this, because when I see others using this product, it's like a mist, and that's definitely not mine! And this makes me not want to use the product because then I have to put it in my hand first and then in my hair, but when I spray it in my hand, it comes out as such a hard stream that I just end up splattering the product around instead :(

      Hey Thilde Yes, that’s actually true. I have it at home too, and unfortunately, it’s a hard beam, even on others I’ve tested 🤨 I love the product, but it’s a minus for the beam. Hope you find a way that works for you 🤗 All the best 💖
