Specifique Potentialiste - Haarserum

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.

Odeur forte et désagréable

Odeur très forte, incapable de passer par dessu. Je ne recommande pas

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.

Fragrance is insanely strong. I have been using the Living proof scalp treatment for years and it’s fantastic, this one makes my scalp burn and itchy within seconds of applying it. Most probably caused by this crazy fragrance.

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.

Must have!!!!

Saved my hair. Had lots of shedding and my hair healthier now. On my second bottle and bought a third one. Using after I wash my hair as indicated.

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.

A must-have

I love it so much! I have a dry/itchy scalp and it helped me a lot , I put it before going to sleep and when I wake up my scalp seems rebalanced and fresh

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.
