I have damaged hair from blonde dyeing and this product made a noticeable different to the overall look of my hair and prevented further breakageBeautiful product
Using this whole range and my hair has never felt better. Love that it doesn’t weigh my fine hair down and leaves it so smooth and softThumbs up
Received a 50ml sample size of this. I used it on my fine highlighted hair on the days I was using heat styling. My hair felt soft, smooth and protected. Would definitely purchase.Beautiful
I was fortunate to receive this as a gift on a purchase. Lucky me! I've got thin fine hair and this product always leaves my hair feeling super soft. I run it through the ends/tips of my hair with my fingers when I get out of the shower before I blow-dry. My ends have a tendency to dry out so they love the moisture pick-me up!Wonderful smell
I've received 2 samples of this that allowed to use it multiple times and I love it. Protects my hair, smells great and leaves it looking and feeling better.Perfect! Smells great too!
Perfect hair treatment and smells pleasantly!Wonderful Protector!
Amazing heat protector! Make sure to take apply a small amount. There's a silky finish and a great smell! Win-Win!Love this product!
Received this as a sample and ended up purchasing the full bottle. Love the smell and texture and leaves hair soft and shiny. I can definitely feel a difference when using this product on damp hair.Excellent Protectant
A little goes a long way, I blow dry and straighten often and it lasts me months. Well worth the investment. Great heat Protectant, without being too heavy or making my hair greasy.AMAZING!
This stuff is so good! A little goes a long way, and this leaves my hair SO soft and bouncy, not tacky or weighed down or oily. Amazing silky finish, and the smell is delicious and luxe.Best in the market!
I receive this as a sample and I absolutely love it! Going to repurchase it. It's definitely worth it if you compare it to Olaplex when it comes to $ to ml.Great heat protector
I received this product as a sample and I absolutely love it. I use it when I'm heat styling my hair and it leaves my hair super soft. I would definitely recommend and will be buying this product in future.The best!
I have tried several heat protectors over the years, and I realised the cheap stuff from the drugstore was not working anymore. I decided to try this product and it made a huge difference in my hair! I always blowdry my hair, and then is really difficult to style it because it's super dry. With this product, didn't need to style at all! My hair feels and looks super soft and healthy.Changed my life!
Received this as a sample and it has honestly improved my hair in just one week! My hair feels much softer and stronger with this protection from blow drying.Absolutely beautiful
Love the smell. It is like watermelon And the way it makes my hair feel soft and healthyAmazing product
Received this as a sample and now constantly repurchase. It isn't too heavy and doesn't way down my hair but it still manages to smooth visible frizz. I've also noticed my hair feels less dry after frequent heat styling! It is a tad pricey but definitely worth the slight splurge.Great product
Smells amazing, and hair is shinier and smoother after use. I originally received a sample of this, and liked it enough to get the full-size, so yes, would definitely recommend.It works
Got this as a gift with my other purchases, it works well, I applied it before blow drying my hair and it did protect my hair from heat.Nice
Love this product. Great heat protectant, leaving hair so shiny.Lovely
This smells amazing and has a great texture, my super thick and dry hair loves it.Quality leave in for heat protection
I decided to invest in a top quality Kerastase heat protectant as my hairs health was declining. A little goes a long way and it protects my damaged strands for further deteriorating from heat styling. It is expensive but as expected it delivers excellent results. 10/10!Good product for fine lengths
I tried this product when we have promotional offer. It smells nice, doesn't weigh my hair down and seems to help detangle my hair. My hair feels smooth and looks lovely and shiny once styled. But to be honest, the price is a little bit expensive comparing to other Aussie hair products.No difference
This product came in one of the fantastic goodie bags, which was a lovely opportunity to try this brand. However, considering its price, I wasn't impressed. It made my hair more frizzy (I do have crazy hagrid hair), but I also didn't notice any other improvements such as easier to manage, softer, smell etc., even after a few tries.Beautiful hair product
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 wellGreat for controlling frizz
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!Light & effective
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.Great heat protectant
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.Incredible
I received a free sample of this and loved it so much I went and purchased the full size. Leaves my hair feeling the softest and silkiest it ever has! To the point where even my partner commented on how soft and nice smelling my hair was after I had used it.Amazing
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 wellAmazing stuff!
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.fave hair product
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 conditionLove this product line
I love this product line. It does wonders! Especially helpful for over coloured hair or if you straighten your hair frequently etcsmells good
this smells really good and helps hydrate and nourish my hairQuiet achiever
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!Great product!
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!unexpectedly good
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.Soft, smooth hair
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.luscious
received a sample size of this. Hair feels fantastic when i use it. Feels very soft and luscious!Great
Really nice heat protector. Left my hair feeling so soft and with minimum frizz. Will repurchaseMakes hair look healthy and soft!
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!Rich and protecting
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...Read MoreGreat cream
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 healthySmells great
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 againImpressive
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.Beautiful leave in
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.Impressed
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.Great quality product
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.Not a wow product
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...Read MoreHydrating and caring
This hat protector/leave in treatment leaves hair smooth and hydrated, and is especially effective when used with the rest of Extentioniste range.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.
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...Read MoreBEST product for protecting hair from heat-damage!
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...Read MoreDoes the job
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!Works a treat
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!Works a treat

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?Smells amazing

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!lightweight cream
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.Perfect for before straightening hair
I use this styling cream before straightening my hair to prevent further damage. It leaves my hair feeling super sleek and smooth.Great
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!Amazing
Amazing heat protectant that doesn’t feel greasy at all. Leaves hair smooth and creates the perfect style while using this
