    Application & Amount

    How should I apply this? Should I apply it from the ears down or from the scalp all the way down? I have completely long hair that goes down to about my armpits, and it's not super thick but not thin hair either, so how many pumps should I use?

      Hey there!😃 👉 Here’s how to use Kérastase Resistance Sérum Thérapiste: It’s a leave-in that should stay in the hair. Always apply to towel-dried, damp hair (you can also put a little in dry hair after styling for extra protection). Start from the ears and go down, avoiding the scalp – otherwise, the hair may feel heavy or greasy. For your length (armpit-length and normal thickness): 2 pumps are usually enough. If you have very dry ends, you can take an extra half pump just there. Distribute it evenly between your hands and comb through with your fingers so it doesn’t clump in one spot. Blow-dry or let the hair air-dry – the serum protects against heat up to 230 degrees. ✨ Tip: You can add a little dab to the ends the next day if they feel frizzy or dry! Take care!❤️

    BEST HAIR SERUM!

    BEST HAIR SERUM EVER! Plus it smells so good. Helps fix hair strands that have been damaged by bleaching, and also tames frizz. A MUST for anyone with a bit of damaged hair.

    Luxurious but nothing special

    A fairly good product but I don't notice any long-term results. The hair looks good when using the product but there are no successive improvements to the hair. Which feels disappointing since it costs so much.

    Heat Protection

    It says that it protects the hair from heat. Is this product enough if you want to straighten or curl your hair? Or should you use something else as heat protection? Thankful for an answer!

      Hey Wilda 👋 This product protects against heat up to 230°C 😍 If you have a flat iron or curling iron that is not hotter than that, you can use this product before styling 👍 Take care!

    Good scent

    The scent was absolutely lovely and left a fresh feeling in my hair, but I didn't notice any significant nourishing effects and the effect wasn't long-lasting. So it's not really worth the price, and I wouldn't buy it again.
