The smell

I use to love Kerastase, but the smell of this product is overpowering! If you are sensitive to smell it could be not a good option for you. This is a first time a feel disappointed by a Kerastase product.

A Totally Underwhelming Product

I was so excited about purchasing this as I typically love Kérastase products, but this one was a complete letdown. It didn’t revitalize or refresh my semi-dry scalp in any way at all. I was hoping for that tingling or cooling sensation that comes with some scalp products-but I felt literally no difference at all. It felt like putting an olive oil into my scalp that then turned into nothing. I’ve been using this product for two weeks and I cannot say it has changed my hair or scalp for better or worse. Definitely save your money for a different scalp product that reaps benefits.

It is very strongly scented, like perfume! Can be irritating. It nourishes the scalp a little bit but the scent counteracts it by being irritating to the scalp. i wish they had it be more natural, maybe it would've been a better product.

I love this product. It doesn’t make my hair greasy at all and it has definitely helped my itchy scalp

Impressive product

Wow, I'm very impressed after using my free sample. I have been dealing with an itchy scalp and dandruff for a while now and nothing seems to work. After one application, my hair is not itchy and extremely soft. It even looks shiny and healthier than it usually does. As for the smell, it's not as bad as some people claim, some people are so dramatic. It does have a strong perfume smell but it dissipates after a little while and if you use other hair products, it won't be noticable.

Not working

I was recommended this after the app test. I have scalp eczema and this product did not help smooth the symptoms.

Saved my scalp from long-term dermatosis!

A heroic product! for about 4 years, I suffered from dermatosis of the scalp, an unexplained etiology on the top of my head. I've tried everything, including clinical treatments. After a course of this serum for 6 months, I forgot about dermatosis on the scalp! I repeat now 1 time in 3 weeks. I apply it all night, in the morning I wash my head! It’s my first time when an experience of not-medical product with such life-changing results

Scalp is much less itchy after using this regularly, my scalp feels fresher for longer and doesn't get as oily as quickly. I can go longer between wash days when I use this.

Zero for Smell

While it instantly felt like it calmed my scalp, made my hair shiny- the smell is so off putting! Very strong chemical cheap cologne smell. I made a mistake of using it the first time before work time and I had to jump back in the shower

A must have!

This really helped my scalp! My scalp has been very dry this winter and this helped so much. It also smells really nice.

This product has a very cooling and soothing sensation and is enjoyable to use. After 5 days of use scalp itchiness is minimized. The only reason for 4 stars instead of 5 is that the product, although not greasy, does leave a slight residue on the hair. If you have thick hair or black or brown hair you probably wouldn't really notice it but if your hair is fine or medium in texture or blonde or redheaded the residue will most likely be visible. It is visible in my hair and I have wavy blonde hair with medium texture.

Regret spending so much on this.

What does this do? Other than smell and make your hair feel wet. I have to use it as I have bought it now. Does nothing.
