✨ Kérastase Genesis Serum Review ✨
This is my second time purchasing the Kérastase Genesis Serum and I had to stock up with a few bottles during their sale because this product is quite literally magic in a bottle! My hair feels stronger, my scalp is healthier, and I’ve noticed way less shedding and breakage—it really works! If you’re experiencing a lot of breakage and/or shedding, please try this product! You will not regret it!

I've only been using this for about 2 weeks now, but I can honestly say this is one of my favorite hair products. I notice I don't shed nearly as much while washing my hair in the shower! I have fine hair, but I have a lot of it. I highly recommend this product to anyone who wears their hair up a lot.

[This review was collected as part of a promotion.] This has become a must in my routine. It’s super lightweight and doesn’t make my roots greasy.

Game-Changer for Weak, Thinning Hair!
[This review was collected as part of a promotion.] I’ve been using the Genesis Serum Fortifiant consistently for the past few weeks, and the difference in my hair is incredible. My hair was feeling weak, shedding more than usual, and looking flat—but this serum has brought it back to life.
It’s lightweight, non-greasy, and absorbs quickly into the scalp without leaving any residue. I love that it doesn’t weigh my hair down or make it feel oily like some other serums do. After regular use, I’ve noticed less breakage, stronger roots, and even a boost in volume.
The scent is also super luxurious—clean, subtle, and salon-like. It truly feels like self-care in a bottle.
Highly recommend for anyone dealing with hair fall or thinning. Stick with it—consistency is key—and your hair will thank you!

Strong smell, bottle only lasts 2 weeks
Smells incredibly strong and unpleasant. I've gotten used to the smell now but I don't enjoy it. A bottle lasts about 2 weeks if you use as directed. I've been using it a month now and haven't seen any improvement to my hair. Will continue using to give it a fair chance.

Smells amazing!
It is too early to tell if it works, but smells AMAZING!! Product consistency is extremely watery and hard to apply only to roots, easy fix when you use a plush headband. It does run to the lengths of the hair, however, it leaves my hair really soft! I give 3 stars because of the price and the quantity you have too apply, this is too expensive, but I’ll give it a try for a couple of months!

Don’t hesitate
I’ve been using the Kérastase Genesis serum for a while now, mostly out of frustration with persistent hair loss. Honestly, this oil has been a quiet game-changer for me. I remember those days when I’d see clumps of hair in my brush—now, there’s a noticeable reduction.
The texture is just right: it’s light, non-greasy, and actually feels like a treat when I run it through my hair. I’ve noticed not only less shedding but also an overall healthier look and feel to my hair. It’s become a staple in my personal care routine, and I genuinely feel more confident about my hair.
If you’re dealing with similar issues, I’d say give it a try. It’s been a personal win for me

Wonderful but…
Ok. So I am really liking this product so far. I have only been using it for two weeks…not long enough to know how well it works. But be careful with the applicator. While squeezing the little applicator and massaging it into my scalp, it slipped out of my slippery fingers and fell into the sink and the glass tube shattered. I thought it was all contained in the sink. But two days later (we were on vacation) my husband mentioned that he’d had something in his foot for two days that was killing him. After digging with my eyebrow tweezers, we dug out the tiny round glass tip of the little tube. Now I’m stuck with how yo get the rest of the product out of the bottle and on my hair. That being said, it smells wonderful and does not leave your hair greasy. I hope it works with my hair fallage.

Amazin!
[This review was collected as part of a promotion.] It's great for straight fine low porosity hair! It's extremely light weight, similar texture to water but a bit more thick. It's refreshing to apply on my hair. For reference I have pcos and andogenetic alopecia and this doesnt irritate my scalp. I havnt seen hair growth but I see less breakage so Im already on my second bottle. Not a huge miracle product but I like the progress and light weight serum very much!

Doesn’t make my hair greasy. Has slowed down the amount of shedding I am experiencing. The fragrance is quite strong so might be off putting to some. The instructions say to use 4 pipettes each application but I find that to be too much and would go through the bottle too quickly. I use 1-2 pipettes each application.

Magic in a bottle
I know everyone writes “magic in a bottle” about products they enjoy these days but this is the real deal. I have long but very damaged hair that was stuck at the same length for months, plus a small thin patch on my left side of my hair and this product has helped me fix both. Not to mention that it smells great and doesn’t leave your hair feeling weighed down and sticky like normal hair oils and serums do. I’ve already purchased my 2nd bottle and I’ll be a forever loyal customer as long as the formula stays the same.

Overhyped
[This review was collected as part of a promotion.] It’s very water like it runs through my hair fast. It finished very quickly, lasted 2 weeks and I have not noticed any difference. Scent is strong so wouldn’t recommend if you’re sensitive to smell.

Pretty Good Product
[This review was collected as part of a promotion.] I've been using this product for a few months now. I haven't seen much hair growth but have seen less hair shedding. At first the scent was a little too much, but I moved passed it. Now I don't even notice the scent. I will continue to use this product for a few more months to see if it does in fact promote hair growth.

Did not work for me
Bought this Friday 6/27 and I have been using it daily for almost a week.
I wash my hair 5-6x a week and have been doing so my whole life basically. I bought this because I noticed my hair started shedding more.
The Saturday I did not wash my hair and my hair was shedding a lot while brushing. Sunday my hair shedding was double what it normally is. I thought maybe it was because my scalp was super sweaty. But I used it for 3 more days and the shedding was more than what it is daily without this serum. For me personally it did not work, it made me shed more. I was optimistic it would help reduce my hair shedding but it didn't work for me, it made me shed more. So after 5 days I decided to stop it. So on the hunt for another serum.

YOUR HAIR IS WORTH IT (and more)
I found the Genesis Hair Serum while deep-diving through TikTok for hair fall prevention—especially as someone dealing with postpartum hair loss. So many girlies recommended it, and I’m genuinely so thankful they did!
Yes, it’s definitely a bit pricey, but with consistent use, the results speak for themselves. It made a huge difference in my shedding, and I started noticing stronger, healthier hair over time. As a new mom, that kind of progress is priceless.
It might hurt my pockets a little… but honestly, I’d rather have a full head of hair than regret not doing something about it. 100% worth it! 😍 Ladies get it I’m telling you! 2025 no more hair fall let’s go 💪🏼

Scent triggers migraines
Unfortunately I won't likely know if the product works or nor because of how overly scented it is. It would be appreciated if it was unscented as the smell triggers instant migraines. I'm not sure why manufacturers feel the need to scentify (yes, I made it up) everything, failing to take into consideration that I'm not the only one who cannot use these products. Maybe it is something in the ingredient(s) itself that is naturally scented, but if not, please stop scenting your products.

Amazing for hair fall
[This review was collected as part of a promotion.] I’ve seen a noticeable difference in my hair since using the Kérastase Genesis Serum Fortifiant. It’s lightweight, smells great, and has helped reduce shedding significantly. My scalp feels healthier and my hair stronger. Highly recommend for anyone dealing with hair fall!

Amazing
It’s literally the ONLY THING that has worked for me to help with fallout and it works so well to the point where even my hairdresser noticed I had little to no fallout when washing my hair. REALLT is worth every penny, I’ve gone through two bottles already.

The only product I am not in love with
Honestly, I stopped uaing it after few times. Not sure if it does something, but to me it felt heavy on my scalp, gave me some feel that I can't comb trough. I don't like the feeling of the peoduct on my scalp. So wastw of money for me, but again please do not let my comment influence you, I dis not use this long enough to tell if it is helping or not.
