Ok

Didn't love this Kerastase conditioner which is surprising. Left my hair feeling nice... but nothing special. For the price I don't think its worth it.

    Gillian

    I have mid-length straight hair and I find this conditioner hydrating without weighing my hair down. My hair is in better condition with less split ends/damage despite using heat styling tools. I have repurchased multiple times.
  3. My best friend

    Jodz

    This really works my hair has grown so much and feels great
  4. The best!!!

    Bre

    This is the best conditioner for long hair lacking strength. As it is protein based it isn’t super ‘softening’ however hair feels so much stronger after use.
  5. Go to conditioner

    KBA

    Leaves hair silky with a pleasant but subtle scent. Hooked after trying the travel set, this is now my favourite conditioner!
  6. nice product

    Jasmine

    works well, nice and soft
  7. Grew my hair like crazy

    Lish

    The combination of this and the matching shampoo sent my hair growth into overdrive! If you need protein in your hair, this set is the choice for you. Just be mindful to counter with moisture after prolonged use so you hair doesn't go coarse.
  8. Smells amazing

    Caroline

    Not sure if it has helped with strength and length, but leaves hair soft and fresh, love the smell
  9. Weightless, shiny and long

    TMcGee

    Love this conditioner - my hair feels conditioned without the weight and greasy roots, also supports hair growth and length.
  10. Happy with this conditioner

    Chelsea

    My regular conditioner. Great for dry hair.
  11. Just OK..

    Kerrie

    I purchased this with the matching shampoo and it didn't feel like anything special for me. It left my hair feeling heavy yet dry? Smells nice but I wouldn't repurchase.
  12. Get the shampoo and conditioner

    Teish

    I have fine hair but lots of them so it is quite thick yet looks thin and damn This combo just works for my hair like no other
  13. Effective

    Ber

    I use this conditioner with the shampoo, definitely helps with the dry ends.
  14. Good

  15. Disappointed

    L

    Was not very impressed with this product considering how expensive it is to purchase.
  16. Lasted ages

    LH

    One tube lasted me ages. I only put conditioner on the mid and end of my hair because most are too heavy for my oily scalp. This one did the job well without weighing my hair down. Straight, thick hair type
  17. Favourite for fine blonde hair

    Ariana11

    I had always hesitated with Kerastase because of the price but this is worth it. I always come back to this conditioner which softens my hair, keeps it healthy and in good condition without a build up or heaviness. Absolute favourite.
  18. Nor worth the hype

    Ris

    Honestly not impressed with this, doesn't make my hair soft and tends to leave the centre a bit greasy even when rinsed really well. Also not sure who thought the screw off lids were a good idea, super inconvenient!
  19. Lifesaver for wavy hair!

    Isabella

    Having regular bleaches done to my dry, unruly wavy hair. I tend to lose my natural wavy curl pattern for a few months in between salon appointments. This conditioner changes that! My waves are back straight after getting my hair dyed, it feel smooth and silky. Couldn't be happier! (avoid roots though!)
  20. A bit disappointing

    Madison

    Was not very impressed with this product considering how expensive it is to purchase. Really did nothing for my hair apart from making it a bit greasy even after washing it out properly. Not the worst product however certainty not worth the large price tag unfortunately
  21. Just Ok

    Tiffany N

    I found this conditioner is just ok for my hair, not reay makes hair soft and smooth so i dont think its worth the money, even i have damanged hair. Will try other product range from this brand
  22. love the smell so much

    Natalie

    wow in love smells good and good heat resistance
  23. Smells nice, although not sure how well it works

    Vicvic

    It certainly has a nice sweet scent, but I don't notice any particular differences in my hair softness.
  24. Detangles fast

    Woody

    By far the best condition to loosen tangles and knots. My hair is extremely curly and this just detangles so fast with less hair fall trying to get knots out. It goes a long way with only a 20c coin size usage per wash.
  25. Nice & conditioning

    Megsie

    Very conditioning and nourishing conditioner
  26. amazing

    Brie

    perfect for all hair types and smells amazing
  27. Nourishing conditioner

    Mel

    Love this conditioner! I have fine hair that is prone to split ends and breakage. Normally I avoid conditioner just because it weighs my hair down and gives it an oily appearance but I found this conditioner not heavy and very nourishing. I feel like it’s helped decrease my split ends too.
  28. All reputation, no results

    Zoe

    Every hairdresser I’ve been to raves about Kerastase. I used this conditioner on my fine, long, bleached blonde hair following the Extensionste shampoo and it offered bare minimum hydration. I could’t run my fingers through my hair after shampooing and this conditioner just got my hair to “normal” - not feeling hydrated or conditioned at all. I would be repurchasing from this brand as not only doe...

  29. AMAZING PRODUCT - LOVE IT.

    KR81

    OMG - What an amazing product. I watched the video that Amelia Porter from Adorebeauty posted and I purchased all the products that she was showing and I followed her instructions and can I say WOW my hair feels soft, silky, shiny first go.
  30. Disappointing & not worth the price tag

    Tahls

    I really wanted to like this but can’t see what the hype is! I needed so much product to be able to coat the hair and used it twice as fast as the shampoo. Hair was left knotty and felt quite dry. Stick to a bond repairer for damaged hair.
  31. Quality Kerastase Conditioner :)

    Emily

    This conditioner is worth the money, I didn't expect to see results immediately as I have damaged hair but I was pleased with the results from the first wash and blow dry.. I feel it is worth noting that I used this conditioner with the matching shampoo which I feel contributed to the results I saw.
  32. Average

    Kate

    I had high expectations for this product however aside from a nice scent I didn't notice any other advantages to it over other cheaper conditioners. I didn't find it very good at detangling and would have preferred it to be more conditioning.
  33. My first bougie hair product

    Steph

    My hair is straight and in pretty good condition and so I didn't need a miracle, that being said, for $46 a bottle I was hoping to be a little bit more blown away than I was. It's definitely a lovely conditioner that smells great and leaves my hair shiny but still can't decide if it's worth repurchasing! I've been using with it with the matching shampoo.
  34. Great for breakage

    Shani

    Bought this along with the match shampoo. I’ve only used this for a couple weeks now and it’s really helped my hair health which is generally prone to breakage and dehydration

  36. Not for me

    Nika

    I had high hopes when purchasing this product to help with my splitting ends and hair that just could grow long. I used it together with same series shampoo but I didn’t notice any difference in my hair. I felt that I needed to apply a lot of product to saturate hair otherwise I wasn’t able to brush it out after. My hair actually felt dryer with every use. Would not recommend.
  37. average

    leigh

    I had high expectations for this but it did not blow me away. It left my hair soft but no different to cheaper brands.
  38. Fantastic Conditioner

    MareeQ

    This conditioner has transformed my hair in a short time to smooth and healthy. I have long fine hair that is subject to breakage and my hair feels stronger with each use. Don't be fooled by the small size as you only need a little and it doesn't weigh down the hair either.
  39. Luscious

    Fay

    Only need a little, goes a long way, I use this with the shampoo and my hair is so much stronger, I have been lucky with bleaching my hair but it gets weak. My hair grows so long when i use this conditioner
  40. great for oily hair

    nat

    I have been using this conditioner with the shampoo and I love it as it is not heavy and doesn't leave my hair greasy.
  41. Everyday use

    Linh Ph

    Received this in a mini size included in goodie bag, I fell in love with it at first use. Just a tiny amount applying on the hair and my hair feels soft, lightweight and no more frizz.
    Highly recommend this item!
  42. Nourishes dry hair

    Tiana

    I can’t believe how soft and nourished my hair feels after using this. I have quite dry, long hair and find with many other conditioners that I need to repeat the conditioner a few times to really feel a difference. I use a fairly small amount, and find that my hair is so much more manageable and soft after! Would recommend to anyone with dry hair!
  43. Thick and Creamy Hair Food!!

    SJ

    This conditioner is amazing! The thickness and creaminess of this product is so luxe. Hair feels so soft, smooth and nourished after use.
  44. Hair care staple!

    Dii

    Smells amazing and makes my hair feel so smooth! No frizz at all.
  45. No difference

    Supriya

    I have dark thick coarse frizzy hair that has been coloured. I didn't see a major difference in my hair, I also used this in conjunction with the shampoo and the mask
    Will not purchase again
  46. Love

    Courtney

    This made my hair baby soft (and it’s normally drier as it’s on the curly side). I used the matching shampoo beforehand and loved the combo. It smells amazing and made my hair feel so soft and clean!
  47. Saved my breaking hair!

    bella

    I've been using this range by Kérastase for a while now (with the matching shampoo and resistance therapiste serum) and honestly can say it does exactly what it claims to do. My hair had been through perms, bleaching and colouring and was literally breaking off every time I touched it, I was desperate to try to save what I had and also promote some new growth so I invested in this range from Kéras...

It’s a slight pain to have to dry your hair between sha...

  50. A miss from me

    Lauz33

    Am I missing something with this conditioner? I’ve been getting blonde foils for years and always on the look out for hair care that helps to strengthen my fine hair. I tried this 3 times and every time it was a bit of a mess. It doesn’t seem to hydrate much at all. I had to put in lots of leave in treatment (olaplex no 6) just to be able to begin getting a brush through my tangled mob. I suppose ...

  51. Love This Conditioner

    Lily

    I use this along with the matching shampoo and it leaves my hair feeling and looking so soft and shiny, and I love the fresh smell that goes along with it. The product does well to detangle my curly hair also.
  52. Excellent conditioner

    Mia

    This has worked wonders on my damaged hair. For ages it seemed like it would just not grow and kept breaking, since using this I have noticed a dramatic change in my breakage and my hair is also noticeably longer. It’s expensive but worth every penny to me
  53. works!

    jassie

    I noticed a diff in. my hair after I switched to this set - you need to follow the instructions. after shampoo, towel dry you hair and then apply the conditioner and leave it in.

    Cant wait to see how my hair will be after a few months of using this
  54. A little disappointed, but good overall!

    Hannah

    I bought this conditioner along with the shampoo and heat protectant from the same range. I have to admit I was a little disappointed. Since I have long, fine, curly hair, my hair is prone to breakage and drying out, I was hoping this conditioner would be exceptionally nourishing and strengthening for my lengths, this wasn't really the case.

    I found that whilst it was by all means a a...

  55. Helps me maintain long and healthy hair

    Olive

    I have definitely noticed the difference to the ends of my hair having used this conditioner. I have found that the ends are less prone to splitting and breaking and as such, it tick the value-for-money box for me.

    Note: I also use the Kérastase Densifique Shampoo as well as the Nutritive Thermique as part of my hair care regime.
  56. MUST HAVE!!

    Amy

    Recommended by my hairdresser, my hair has more volume yet super soft. Gives a natural bounce and fullness, worth the money! I have the whole range in the Resistance!

    coming from just using drugstore conditioners I didn't think this could be that much better but honestly, it is worth every extra penny. I love the way it leaves my hair feeling so soft and strong.
  61. Wow

    Gerogie

    This is the best conditioner I have ever used. It smells soo good and leaves my hair feeling amazing. It was so dry and damaged before and after using this for a few weeks it is now beautiful and soft and healthy
  62. Great results but wears off

    Latenights

    Improved the texture of my hair in the first few uses - smooth and easy to brush through. But with continued use the results are about the same as a cheap conditioner as my hair started tangling and breaking again. I wonder that the hair gets used to this product after a while and it is no longer effective.
  63. Very good product

    Diego

    Basically the best conditioner I’ve ever tried. Recommended by my hairdresser, my hair has more volume yet super soft. I comb through conditioner before rinsing to detangle my long hair! Gives a natural bounce and fullness! Love it!
  64. super strengthening

    lee

    this helps strengthen your hair and it does really help
  65. My favourite conditioner

    Rose

    This conditioner is one of my favourites. It smells amazing and works like a charm. I’ve bought this product many times and I prefer to use this conditioner after shampooing rather than the mask. This conditioner is light weight and you only need two small droplets to lather your hair.
  66. Smells so good!!!

    Jess

    I love that this conditioner packaging doesn't have a big hole, it's very easy not to use too much - which i always do... Apart from the packaging, the conditioner is very nice smelling and leave hair very smooth.
  67. not worth the price

    Jenna

    it is a nice conditioner but wouldn't say it did anything for length or longevity of hair beyond other high quality products.

    I use this after the Kerastase Dermo Calm Riche shampoo which I use for my sensitive scalp. It smells great and leaves my hair soft and silky which I love as my hair is highlighting and a little dry.
  72. So nourishing!

    Lucinda

    I've got incredibly damaged frizzy split and course hair from keratin treatments and this is the best conditioner I have found! I genuinely think my hair is repairing! Obviously a conditioner cannot change the texture of your hair, but my hair feels nourished and hydrated again! Based on this conditioner, I'm going to be investing in the Résistance Extentioniste range!
  73. Definitely recommend!

    Tay

    Love this conditioner! The smell & packaging is amazing and it makes my ends feel super soft and strong.

  77. Not as good as the hype

    Leah

    I have dry coarse wavy hair prone to a bit of frizz and this didn’t really help it much. It weighed it down and reduced frizz at first but on the second day it was back doing its frizz thing only oily. Too heavy even for my coarse hair.
  78. Made my hair long and healthy

    karri

    My hairdresser suggested this product for me as I have bleached blonde hair. It repaired my hair and made it nice and healthy. I noticed a big difference in length within a month!
  79. Lightweight yet hydrating

    Ellyse

    I use this every second wash in conjunction with the Extensioniste Masque and can barely tell the difference in my hair which says a lot in terms of how good this conditioner is because the masque is beautiful!!
    Lightweight, smoothing and smells divine. Would recommend.
  80. A really nice conditioner

    KJ

    Paired with the shampoo in this range, I’ve got great results. After about two months, my hair became thicker and it definitely felt stronger. My hair is wavy and thick, and I definitely have a lot of baby hair around my face at the temples. While I wouldn’t say that the baby hair had grown out, it looks thicker and healthier. Along with the shampoo, I’d definitely recommend this product.
  81. Love Kerastase

    Robintam

    I love this conditioner and have used it for a while now! Not only does it smell devine but it keeps my hair healthy and smooth and lasts longer between washes!
  82. The Serum for Unruly Dry Hair

    Zain

    After reading the reviews I thought I need to try this product and it has not disappointed. This is the second time rerun purchase.
    It smells amazing, works brilliantly on thick course and unruly hair and within 2 usages I noticed my hair was easier to manage, shinier and felt softer. Would highly recommend !
  83. Nice

    Nadya

    Same as other Kérastase conditioners, I don't find this one to be an absolute necessity if mask of the same range is used. But I apply it on those days when I don't use the mask to give hair some extra hydration and shine. Works well together with Extentioniste shampoo.
  84. THE PERFECT REMEDY FOR DRY SUMMER HAIR
