    Love

    I use this every time I style my hair and it really helps reduce hair breakage.

    Strong scent

    Too strong of a scent, I couldn't use it at all.

    How often?

    Can you use this product after every shower, or is it like WOW's dream coat that you shouldn't use too often?

      Hey hey Lotta 🥰 This spray is recommended to be used after every wash on towel-dried hair and to be blow-dried in, for the best effect 🤍 I hope this will suit you and your hair super well! Good luck!

    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?
