The solution to my problem.
My hair loss stopped in no time. I like that it's a light but effective product; I don't feel any residue on my scalp. I would repurchase it as often as necessary.

Definitely less hair loss and breakage
I have been using the Genesis shampoo and conditioner for about a year and have noticed a real difference in the condition of my hair. I have shine and have alot less breakage and hair loss. It definitely works. It helped almost immediately when I started using it.
I am thinking of adding a hair oil or serum and struggling to decide which one to choose.

I've gotten a few bottles of this and I genuinely love it! The smell is a little much at times so if you have a sensitive nose then this product probably isn't for you. But when it comes to the product itself ive seen a big difference in my hair!

Nope.
Product is thin liquid & drips all over scalp & hair. This was a big deal for me because it felt very drying to my hair. And I couldn’t keep it isolated to scalp. Did not see any difference in hair regrowth or thinning.

Game changer
I’ve been using the Kérastase Serum Fortifiant for a few weeks now, and I can honestly say it’s a game changer for anyone struggling with hair fall or weak roots. I started seeing less breakage within the first 10 days, and my scalp feels healthier and more balanced overall

Kerastase Genesis
I bought this product hoping it would help with my thinning hair, and I’ve been genuinely impressed with the results. After just three weeks of consistent use, I started noticing a real difference—my hair looks fuller, feels healthier, and even seems to be growing in areas that were noticeably thinning before. It’s given me a big boost of confidence, and I couldn’t be happier with the progress so far. If you’re struggling with thinning hair like I was, I can’t recommend this product enough—it truly works!

Doing Okay So Far
I havent been using it long but my review is based on the fact that I can use it on dry hair and it does make your scalp/hair greasy or anything. My only thing is the smell is subtle but strong. I try not to use it on dry hair right before bed otherwise the smell can be a little strong when trying to sleep. I would recommend just making sure the product dries fully if it bothers you, after that the smell is no issue.

I really like this serum. This is my third purchase. My hair shedding decreased. I just dont like the overpowering frangrance, but this issue refers to all kerastase products. Some of then would make me sneeze a lot. But if it comes to what it promises, it delivers, and the bottle last about a month. I like that its watery.

Love,

I am 55 years young with long hair. I had been noticing significant hair fall every time I was washed my hair. I starts using this product daily, at first, then every other day. My hair falls 95% less and is growing in thicker than it’s been in years.
My only complaint is that the scent, while pleasant, is strong. I found that if I put it on my scalp about an hour before bed time the scent is not as strong when we go to sleep.

Best
Best hair growth serum in the world. It reduced my hairfall in 3 weeks of consistent use. I use it only twice a week

I love it so much

I’ve been using this and notice that my hair has been much stronger. I’ve also noticed less fall out.

A voir.. si il y a des résultats
Je test le produit depuis seulement 1 semaine..
Mais pour le moment je peux dire qu'il graisse mes cheveux (j'ai les cheveux mixtes), et cela n'aide vraiment pas.
De plus.. j'imagine la vitesse à laquelle le flacon va se vider.. Un flacon ne servira pas pour la cure de 6 semaines.

The best product
[This review was collected as part of a promotion.] The Kérastase Genesis Serum Fortifiant is a great investment for those experiencing hair fall due to breakage. With continued use, it visibly improves hair strength and scalp health. Ideal for anyone looking to fortify their hair and prevent excessive shedding.

not worth the price or wait
If you can’t keep it stocked there’s no point. I love this product but the issue is that it constantly sells out, and they charge sooo much for such a small amount. I am currently looking for an alternative as there are many different ones available. I love a brand that recognizes a need and fulfills it, it just feels like this company takes advantage. I like consistency and this brand fails at that.

The holy grail for scalp serum
My hair has always been on the thinner side, but even more so post partum. This helps save my hair and doesn't leave behind any grease or residue.

Amazing hair serum
[This review was collected as part of a promotion.] I started using this a couple of years ago. It is amazing and it does work. I continue using it for maintenance now. You definitely need to try this if you have thinning hair
