My fickle (sometimes oily, occasionally dry) scalp had a dandruff issue that was very embarrassing, especially in the winter! Boy did this shampoo work wonders for all of my hair issues! After only one application, there was no sign of my dandruff. Additionally, it kept my hair feeling fresh and greasy-free. On the second day after shampooing, I always go for the dry shampoo bottle, but this removed that requirement. My hair simply feels so clean. I doubt I'll ever switch to another shampoo. It is pricey, yes, but if you struggle with a dry, flaky scalp and/or hair, it is really worth it.

I love the Kérastase purifying and fortifying shampoo. It does a great job of removing product buildup and leaves my scalp and hair feeling great. It helped bring back more of my curls which have been flattened out from using other hair products that my old shampoos could cleanse properly. Definitely recommend you try, Sephora and a lot of hair salons carry it.

BEST SHAMPOO EVER!

I have been using this shampoo for two or three years (as long as it's been around). I buy it online or in Europe as it's not available from the Kerastase salons in Seattle. I have extremely sensitive scalp skin but also an oily scalp: hard combination to please. Bain Divalent both cleans my scalp really well and absolutely does not irritate the skin on my scalp nor on my body (use as all over cleanser). This is the best shampoo I have ever used. I'm happy to see it (finally...) in a large, more economical, more earth friendly size. Do us all a favor and don't discontinue it----as is so often the Kerastase trend. This is a perfect shampoo for sensitive, oily, fine haired people. I cannot say enough good things about it. Everyone in my household uses it religiously ... MoreI have been using this shampoo for two or three years (as long as it's been around).

Didn’t work on my oily hair

I was so excited to try this after reading the great reviews. I’m so tired of washing my hair every other day; the second day I have to dry shampoo my hair and slick it back into a pony tail. When using the shampoo it does dry out your hair and it made my wet hair squeaky when rinsing. Unfortunately it didn’t work for me and I still had to dry shampoo the next day. Now looking for another solution. I’ve also noticed I’ve now got dandruff, unsure if it’s related to the product.

Do not waste your money

Recommended this product by a keratase consultant. It is terrible. Day 2 after washing my hair feels tacky and dirty. A huge price for an inferior product. I did approach keratase about the advice but as I didn't purchase it directly from them it wasn't their issue apparently. I have used keratase products extensively and always had amazing results so this purchase was very disappointing. Service from Look Fantastic always consistently good.

Game changer for oily scalp / Super underrated

My scalp used to get oily a day after shampooing, forcing me to wash it daily. This frequent washing resulted in brittle and dry hair, despite using numerous high-end shampoos over the years. I couldn’t dream of going more than a day without washing my hair until I found this shampoo. It allows me to maintain healthier hair without compromising on cleanliness. My hair looks freshly washed for at least a day or two after a wash. On my second bottle already.

Hair feels great but greasy next day

This is a lovely shampoo that has left my very fine hair feeling thicker and stronger. However, I bought it for oil control and this it just doesn't have. For reference, while I begrudgingly refrain from washing my hair everyday, my hair has always been VERY visibly greasy the morning after washing. With this shampoo, I did not see any difference whatsoever. For my oily chums, the only thing that has ever allowed me to get more than one day out of my hair was a locally made shampoo bar with apple cider vinegar rinsing and the odd bicarb rinsing. Unfortunately, I also have very sensitive skin, so soap is just something I couldn't keep up. Back to the drawing board!

Made things worse

This did not work for me. I got it as part of the Fusio Scrub set. I have fine hair with oily roots which means I shampoo every day. I also highlight every 3 months or so, but haven't had any hair issues since I switched to Kerastase nine years ago. Based on the reviews, I had low expectations with it working as described, but figured I would try it since it came in the set. There was a nominal difference in how oily my roots were on day 2, but not enough to eliminate shampooing, and not nearly enough to compensate for the damage it caused. It 'roughed up' my hair cuticle, drying it out, creating tangles, and losing the "soft and shiny" I've had for years. I went to my hairdresser two weeks ago and he wanted to know what shampoo I switched to, clearly indicating ... MoreThis did not work for me. I got it as part of the Fusio Scrub set.

I had to pick his chin up off the floor when I said I was using a Kerastase product. (I also reassured him that the damage would be repaired before I came back for my next appt.) I'm sure this works for some, but I caution those with fine, processed hair.

My hair has never felt so good!

I’m in my late 20’s now and have found that my hair has thinned out considerably. My hair used to be very thick and I could go a whole week without washing it. Now, going 3-4 days is a struggle and requires lots of dry shampoo. This shampoo is absolutely amazing! My hair feels so clean and the ends are still nourished and not dry. Since using this, I’m now able to go 5+ days in between washes because it keeps my roots clean and prevents them from getting oily too quickly. I could not be happier with this shampoo! Also, because it doesn’t have it’s own specific conditioner I pair it with the ‘Volumifique Gelée’ conditioner which is a gel consistency and really lightweight. Perfect because it doesn’t weigh hair down but still adds moisture. I also use the ‘Reaistance ... MoreI’m in my late 20’s now and have found that my hair has thinned out considerably.

Smooth and non-greasy hair saver!

I have naturally oily and thin hair. I always use this brand and was just looking for a good-scented shampoo. I’ve really liked this one in particular due to my hair never feeling greasy at the end of the day anymore. It’s a good lather as well. Only criticism I have is that the smell isn’t as strong as I would’ve liked but still good clean smell
