Strong Scent (will give another try someday)

I retuned because the smell was way too strong. Well exchanged. All Kérastase oils are very strong. The one I have now really fades, so I will likely repurchase to try again. I can’t share in results, but love all their other products.

Irritates my scalp and my face. I have hives going from my forehead down to my eye. No notable difference to hair thickness or shine.

Smells nice, but kind of made my scalp itchy. Have yet to seen a difference in my hair from the product.

Glossy hair.

Excellent product, leaves scalp and hair glossy, shiny. Hair feels great. I recommend.

Love it!

I love this stuff! I recently lost a lot of hair from Covid. I’ve been using this every time I wash my hair. It’s very light. I massage it into my scalp and through my hair. It never looks greasy or heavy. The packaging is elegant. It is quite expensive but it’s Kérastase! I would repurchase and recommend.

waste product

NOT RECOMMENDED AT ALL. My hair type is fine and thin. This product did nothing for me. no noticeable difference at all.

I gave this product a solid try and used it religiously every day until the bottle ran out. It did nothing for the density of my hair or my scalp, but it also didn’t make it worse if that makes sense. Everyone’s hair is different but for mine it had no effect. Gave it two stars because it smells nice and it felt good to massage into my scalp every night.

irritating

this serum made my scalp breakout...like a teenagers face. I've never experienced anything quit like it. Needless to say I didn't use long enough to see a benefit. And, holy price tag!

Haven’t noticed any difference yet, and I’ve been using it for few weeks now.

I bought this product in a moment of desperation. I was postpartum and felt like my hair was dropping off in scary amounts (never experienced postpartum before) so I felt like adding this in to my haircare routine just helped me feel better. My hair fell out for a few months and there wasn't much to do about that. Whether or not this helped I don't know.

Meh

This is one of those products I wanted to use every day but it's not as amazing as I hoped it would be. It does help to add hydration to your scalp if you're like me and your skin gets dry in the winter, but that's really its only benefit. If you're looking for a shine serum, I'd recommend Shu Uemera's essence absolue. It's a similar price point but makes a much more visible difference.

No results after a years use

I’ve been using this product every other day for a year now and have seen no changes whatsoever. My hair is still as thin as before and still falls out easily. Very disappointing…
