Most Helpful Positive

Great for controlling frizz

Tiana

This stuff is amazing to use before heating/styling. I find that it reduced frizz around my hairline a lot! I also feel like I have far less breakage when styling. Would buy again!

Most Helpful Criticism

Smells great

Kat

I received this as a sample smells great, I have platinum hair and need to protect it when I use heat. Good barrier, would buy again
  1. Beautiful hair product

    Ashley

    I got this in the recent hair goodie bag and have only had the chance to use it a few times but so far each time my blow dry has looked amazing and shiny and lasted really well

  3. Light & effective

    Amaya

    I received this as a deluxe sample and really like this product. I have very thick and coarse hair and straighten after each wash. Love the smell and find that this product does support a silky look and protects against frizz. I am giving this 4 stars as I am yet to try other heat protectant products so am unsure how it actually compares to any competitors. I would repurchase.
  4. Great heat protectant

    Ange

    I received a generous sample of this and it is a beautiful cream that helps soften and reduce frizz. Love that it is also a heat protectant.
  5. Amazing

    Rachel

    Such a great product! My hair was so soft after using and I could already see a difference with split ends and dryness after the first use. Smells divine as well
  6. Amazing stuff!

    Maria

    This is wonderfully moisturising and it smells divine - not too sweet, not too strong, very luxurious. Highly recommend. I sometimes put too much on my fine hair and then I can feel it when I blow dry my hair so don't over do it like I did.
  7. fave hair product

    Amy

    I’ve been using this for years and it’s the best product I have ever used for my blonde hair hair! Always leaves my hair feeling soft and in good condition
  8. Love this product line

    Issie

    I love this product line. It does wonders! Especially helpful for over coloured hair or if you straighten your hair frequently etc
  9. smells good

    lee

    this smells really good and helps hydrate and nourish my hair
  10. Quiet achiever

    Pechoch

    This is a powerful little product. I’ve been using the sample all week and my hair feels stronger with less heat frizz. After only using for a short time it’s obvious this product would really protect your hair from daily styling and heat. If you want to keep your hair healthy and wrong this is a great investment - and the delicious smell is a bonus!
  11. Great product!

    Hannah

    I love the scent and feel of this product! I haven't really noticed any difference in comparison to previous heat protectants I've tried, but I have minimal split ends at the moment and assume it must be working!
  12. unexpectedly good

    Kayla

    I received a 50ml sample of this and fell in love with it! Smells amazing and it makes my hair super soft! My boyfriend is usually oblivious to these things but he commented how well it worked. The sample bottle has been lasting for ages but I will be buying the full size version as soon as I run low. its my new holy grail hair product.
  13. Soft, smooth hair

    Maggie

    I received a 50mL sample of this product. I've been using it in my hair after washing it to help detangle it while brushing. My hair feels soft and smooth after. Can't really comment on its heat protective qualities as I don't really use heat on my hair.
  14. luscious

    Elisha

    received a sample size of this. Hair feels fantastic when i use it. Feels very soft and luscious!
  15. Great

    Ruby

    Really nice heat protector. Left my hair feeling so soft and with minimum frizz. Will repurchase
  16. Makes hair look healthy and soft!

    Grace

    This is a great product to use in damp hair before blow drying. Made my dry, dead ends look healthy and my hair feel so soft! Also smells great!
  17. Rich and protecting

    Lara83

    I received a deluxe sample of this, so was able to use it for a few weeks. It's rich and creamy, but not heavy in the hair. It smells lovely, and I have noticed that my hair stays smoother for longer. I have long hair that is wavy and frizzy, but I always straighten it at each wash. After a few days the ends will start to look a bit dry and frizzy, but this product has helped to keep them sleek an...

  18. Great cream

    Alexandra

    I received a substantial sample of this and it is a fantastic product. It is not sticky like other leave in hair products and does not leave any residue in my hair. It leaves my hair smelling great and looking healthy
  19. Smells great

    Kat

    I received this as a sample smells great, I have platinum hair and need to protect it when I use heat. Good barrier, would buy again
  20. Impressive

    Dominique

    I received this 50ml in a goodie bag. I blow dry my hair often so was pleased to receive it. It doesn't weigh my hair down like other blow dry products. It smells very nice as well. Keeps the frizzies at bay as well.
  21. Beautiful leave in

    Laura

    I received this as a sample, and after my first try of this product, it left my hair soft and anti-frizz. I applied just before blow-drying.
    I will definitely recommend once my sample runs out.
  22. Impressed

    Maddi

    The cream smells delicious (I use it in conjunction with the rest of the line). I feel as though I already have less breakage and my hair feels considerably better. This cream definitely smooths my hair as it is normally wavy and has some frizz but tends to be straight and shiny after blow drying. Will definitely re purchase.
  23. Great quality product

    Caley

    I’ve been using Kerastase styling products for many years to protect my coloured and overly heat-styled hair. You just can’t beat this; it’s light, not at all heavy or greasy, and it leaves my hair soft and smooth. You only need to use a very small amount so one bottle lasts for months.
  24. Not a wow product

    Mel

    This product is easy to use and distribute through hair. It smells great and doesn't weigh down your hair. Aside from those pluses, I haven't really noticed a significant change in my hair texture after drying and straigtening. I've used Kerastase products before and have usually been impressed with the results, but that wasn't the case here. Given the price tag, I was expecting more obvious resul...

  25. Hydrating and caring

    Nadya

    This hat protector/leave in treatment leaves hair smooth and hydrated, and is especially effective when used with the rest of Extentioniste range.
  26. I have made a big effort this year to put the same amount of care and investment into my hair as I do to my skin.

    Heather S. via BeautyCrew.com

    I have made a big effort this year to put the same amount of care and investment into my hair as I do to my skin. Kerastase is the one brand that always comes up in searches for the best haircare and for very good reason.  While their products may set you back initially, the vast majority will last you long enough to make the investment worth it. My hair has definitely had a big change happen to i...

  27. BEST product for protecting hair from heat-damage!

    MM

    I have used this product for years! It is the BEST product for protecting hair from heat damage caused by blow drying or straightening, etc. I apply it to damp/towel-dried hair after washing, mostly to the ends and baby hair at the front. You don't need much but this product will save your hair and help you to grow it longer (even if you heat-treat or colour/bleach your hair!). Honestly a life-sav...

  28. Does the job

    Jess

    I tend to avoid hair creams because I find they easily weigh down my fine, frizzy hair, but not this product! It's a pleasant smelling cream that I find so easy to work into my hair, and provide that added protection as I blow-dry or straighten - everything you want from a hair-styling cream!
  29. Works a treat

    Hayley

    I originally got this as a sample and ended up buying the bottle because I loved it! It left my hair smooth and shiny rather than greasy and weighed down like other products I’ve used! The only thing I don’t like is the smell - but I can look past that given how well this product works!

  31. Smells amazing

    Luz

    My hair is porous, coarse, frizzy and bleached, so, there are not many hair products I actually love. This leave in treatment smells amazing and leaves my hair soft, what else could I ask?

  33. Incredibly easy

    Daisy

    This is so lovely and light weight. It’s so easy to blend into the hair and makes your hair feel great. Very wonderful and has kept my hair well protected. Yay!
  34. lightweight cream

    Abby

    this is great for pre straightening and I always use a small amount to run over my hair once al straightened, does take a lot to build up and become greasy which is a plus for me, I always avoid my roots as they get oiler quicker but seems to make a nice smooth sleek hair afterwards.
  35. Perfect for before straightening hair

    Isabel

    I use this styling cream before straightening my hair to prevent further damage. It leaves my hair feeling super sleek and smooth.
  36. Great

    amanda

    Perfect for fine damaged hair before using heat tools. Its not heavy on the hair and leaves hair nice and shiny after styling. A go to for me!
  37. Amazing

    C

    Amazing heat protectant that doesn’t feel greasy at all. Leaves hair smooth and creates the perfect style while using this
