Enjoying so far

Nice so far - been using for less than a month at this point, so I haven't noticed any major differences. I like that this is something that can stay in all day/night and does not make my hair greasy. Smells amazing as well.

I love everything about it!

[This review was collected as part of a promotion.] I have a very sensitive scalp and have struggled with a severe hair loss this fall, so I was hesitant to try new products. However, the Kérastase Serum Fortifiant has been a game-changer. It’s incredibly gentle on my scalp—no irritation or discomfort at all—and I’ve noticed a significant improvement in my hair’s strength and growth. It’s lightweight, easy to apply, and truly delivers results. I myst mention that first I used the ampoules against hair loss also from Kerastase. I feel like those helped to stop my severe shedding and then I’ve continuously been using this serum to keep up with the results and increase new hair growth. Highly recommend for anyone dealing with scalp sensitivity and hair loss!

Miracle worker!!

I’m on my second bottle and i have SO much new growth. One bottle lasted me a little less than a month and I even use a little less than it says to. With the price I am sad how quick it goes and wish there was a bigger size. Even my hairdresser was insanely impressed! I use this with the night serum and I’ve had 3-4” of all new growth come in! This is a must have and staple! I was losing hair like crazy on my weight loss journey and this saved the day!! I also LOVE this doesn’t make your hair greasy AT ALL! You can use it day or night.

Kérastase’s hair serum is a game-changer for anyone looking to transform their hair care routine. Infused with advanced nourishing ingredients, it deeply hydrates and strengthens hair, leaving it incredibly soft, smooth, and shiny without feeling greasy. The lightweight formula absorbs quickly, making it perfect for all hair types, from fine to thick, and it helps control frizz while enhancing natural texture.

I PAID FULL PRICE! What MAGICAL SERUM is this?!!

This is a REAL RARE REVIEW*** Fantastic! I’d read review after review of this, then it kept coming up in my social media feeds. Untrusting me wondered if I was just a victim of sponsered paid influencers and algorithms but I decided to give it a go to see// IT WORKS!! Incredible stuff. My hair fall is hardly any at all anymore after using this daily for 2 weeks. It’s very light, I use it everyday (massage into your scalp with freshly washed hands and fingers;) them prepare for the magic to happen. I’m hooked!

It’s an OK scalp serum

[This review was collected as part of a promotion.] I like that this serum doesn’t leave my hair greasy like the OUAI scalp serum or other serums, but I don’t love the fact that the scent is super strong. It smells good, but it’s too much sometimes and it makes me nauseous. It’s also pretty expensive. I don’t notice hair growth with this like I do with the ouai serum. So I feel like it’s okay. It doesn’t do anything positive, but nothing negative.

After 6 weeks of constant use (almost every day) I saw a major difference in my hair fall. Whether or not I used at night or day, it absorbed quickly in my hair without leaving it feeling greasy.
