Spécifique Sérum Potentialiste - Siero Capelli protettivo rinforzante

Great Product

Great product. Does what it says. Thanks Kerastase.

Spécifique Serum Potentialiste Vitamin C

Great Product. I love the smell and it is very refreshing

Impressed is an understatement

For someone who has always had oily scalp and nothing ever worked I wasn't expecting much - but this serum delivered, from the first use. not more oily roots, im lasting nearly a week between washes.

Perfect!

Smells great and feels so nice on the scalp. Only used it twice so looking forward to being consistent

Super itchy scalp and dandruff came back!

I tried this serum as recommended from the quiz and it turns out bad. I fixed my dandruff issue with their Symbiose line, and since I used the products recommended by the hair quiz, it has made it worse. My scalp became oily and super itchy by D2 of washing and my dandruff is back with vengeance. Will definitely won't recommend this.

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.

Absolute Waste of money

It’s definitely not for sensitive scalps as my hairfall increased after applying this plus the fragnance is too strong

Odeur forte et désagréable

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

Scalp Saver

Does what it claims. I am halfway through my second bottle after completing the first round of use. I have itchy, oily scalp and fine hair that is prone to dandruff. My scalp hasn't itched since and my redness has disappeared.

Game Changer

Game changer for scalp issue, that I have rralt with for 20+ years

Excellent product!

Good for dry hair. Helps with hairfall too :) Happy with my purchase

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.
