Great conditioner, needs a few minor adjustments
[This review was collected as part of a promotion.] This conditioner really does a great job of rehydrating hair and giving it softness. I love the scent and I think you get your moneys worth for sure. However the packaging could be better as you have to unscrew a cap to use it. In the shower, this is not necessarily ideal. I was also confused with the wording on how to use this. It says use on towel dried hair, but it’s a rinse out conditioner.

Smooth shampoo
[This review was collected as part of a promotion.] The Kérastase Genesis Conditioner is amazing! After using it, my keratin-treated hair felt instantly softer, smoother, and easier to detangle. It’s lightweight but still super nourishing, and it doesn’t leave any heavy buildup. My hair looks shiny, feels healthy, and stays manageable between washes. A perfect match with the shampoo

Good Conditioner for the right hair type
[This review was collected as part of a promotion.] This conditioner is good, but not moisturizing enough for my fine color treated hair. It helps to let it sit for a few minutes. My one complaint is the cap- I’d prefer if it was not separate.

MISSING: Softness
[This review was collected as part of a promotion.] For a product to claim it “provides immediate strength and softness without weighing down the hair”, I think they need to revisit their formula. After using this product for the better part of a month, I was left with extremely dry hair and scalp that took on the resemblance to straw. Wooooo! 😒 While this might work for some, it definitely did not work for me.

Conditioner that nourishes and detangles effortles
[This review was collected as part of a promotion.] Kerastase Genesis Fondant Renforcateur Conditioner feels luxurious with a creamy texture that detangles easily without weighing hair down. The scent is fresh yet sophisticated, blending citrus, rose, and musk for a subtle lasting fragrance. It is highly effective, leaving hair smoother, shinier, and with less breakage while making combing easier and reducing visible fallout over time. The packaging is sleek and elegant in the signature soft pink design, and sturdy. Though priced as a premium product, a small amount goes a long way, making it a worthwhile investment for healthier, stronger hair.

[This review was collected as part of a promotion.] I’m not sold. Not as moisturizing as I need but made my hair soft and didn’t break as much longer terms. But I’m not sure I see results I was hoping to see for the price. I have very curly, very fine hair so maybe I’m just not the right hair type for it.

Shiny and Smooth
[This review was collected as part of a promotion.] I received this Kerastase Genesis conditioner as a complimentary sample. The bottle is a squeeze tube and very easy to travel work. It’s not too big and can fit in virtually any bag. It has a twist off top which fits securely closed. The conditioner is thick as most conditioners. It is creamy and gives off a citrus scent. I found it to easily spread through my hair and i immediately felt that it made my hair feel soft as it coated my hair in the shower. I allowed it to rest for a few minutes and washed it out. It was easy to get out and made my wet hair feel very sleek. Once it was time to brush my hair, it was odd that my hair felt stiffer and harder to brush through. However, once I managed to get through the different texture, I noticed a sleek and soft texture. My hair was very shiny and looked noticeably healthier even after the first use. I have a lot of frizz and I felt it almost disappeared even though I had only air dried my hair at this point. I felt that my hair felt very clean and it was not weighed down at all. It was bouncy and lively. I am very pleased with my results after using this shampoo and am looking forward to seeing the effects of less breakage and fallout. Overall, I am very satisfied with this formula and would recommend it.

Exactly what I was looking for
[This review was collected as part of a promotion.] Ive been looking for something that strengthens my hair, but is a bit beyond a protein treatment. I had tried a bond repair shampoo and conditioner from a curl brand, and liked it, but could only really use it twice a month max since my hair wasn't damaged. If I used it too much, my hair would be tough and wirery. This I'd like a lighter version of that! I have fine, average density 4b hair and typically wash twice a week. I tried this with the matching shampoo and found using it twice a week was possible, but preferred using it once a week and my hydrating focused set the other wash, or using the conditioner twice and the full set once a week. That is because this conditioner works but it does leave my hair a bit on the dry side. I have to change what leave in/stylers I use to make sure I have soft hair, but I could still use what I already owned. Using this I did see less breakage when washing my hair and my coils are so defined naturally without much additional manipulation. I did find the conditioner worked with well with my other shampoos, but definitely worked best within the set.

[This review was collected as part of a promotion.] This conditioner is hydrating but doesn't leave my already oil-prone hair greasy. I've been using the shampoo/conditioner for two weeks and I can already notice a difference in my hair fall. This line has also been working great for my oily scalp and allows me to go a few days between washes without turning into a greasy mop. My only complaint is the price.

Not too heavy, makes your hair so soft, scent is a
[This review was collected as part of a promotion.] I have been using this conditioner for a month now, and overall have been very impressed.
Starting with packaging, to administer the conditioner, you squeeze on the bottle and a cream comes out, similar consistency to lotion (the bottle is also shaped like a lotion bottle). It is definitely not runny enough for the conditioner to easily come out without squeezing. After a month of use, I am still having no trouble with the squeeze.
The scent is lovely, almost a floral-y scent that lasts all day long. As someone who can be sensitive to smells, this can sometimes be too strong, but it’s just light enough that I still am willing to use it.
The conditioner itself makes my hair so soft but also is not very heavy. A small amount goes a long way. For someone with really oily hair, this is one of the few conditioners that I feel comfortable, putting close to my roots without it, weighing me down too much.
Lastly, I always check the ingredients in my beauty products. While this conditioner is not all gold stars, I don’t feel alarmed by the safety of the ingredients included, and feel comfortable using this in my hair.

[This review was collected as part of a promotion.] This is a lovely conditioner! It smells refreshing and hydrates my curls without weighing them down, which I struggle with because even though my hair is dense, it’s very fine. I always get compliments after I use this in my wash day routine. I like that it’s light enough that it doesn’t cause a ton of buildup where I need to clarify often. It also provides a good amount of slip for gentle detangling.

Good product, odd bottle top
[This review was collected as part of a promotion.] I'd give this 4.5 stars. Love the actual product but the tops to the bottles are annoying when actually using the product. I prefer not having to set a cap down somewhere for hair products meant for the shower. It didn't smell strong when using, but after my hair was dry I would occasionally smell a hint of fragrance that was pleasant and perfume-like without being strong. I'm not sure if it's the shampoo or conditioner with the fragrance, or both. It didn't do anything for frizz or flyaways. I would purchase even with the disappointing bottle.

[This review was collected as part of a promotion.] This was a good conditioner and I enjoyed the scent. The packaging was also very luxe feeling. It added moisture to my hair and overall improved my hair texture.

Thick conditioner, but would still use hair masks
[This review was collected as part of a promotion.] The conditioner is nice and thick- I want a conditioner that is very nourishing and almost felt more like a mask. The scent is nice and I also liked that the conditioner didn’t weigh my hair down. The downside is some of my fine hairs did seem more dry than usual when I used the conditioner- it did a good job with detangling - but would still need to be paired with a deeper penetrating mask

Thank you for your feedback. We're glad you liked the conditioner's thick, nourishing texture, pleasant scent, detangling ability, and that it didn't weigh your hair down. We note your concern that it left some fine hairs drier, suggesting it might need pairing with a deeper mask, which is valuable for our product insights.

Salon quality conditioner
[This review was collected as part of a promotion.] The Kerastase Genesis Bain Hydra-Fortifiant Conditioner makes my hair feel so soft and easy to manage. It’s really lightweight, so it doesn’t leave my hair flat, but it still gives it the moisture it needs. The scent is light and doesn't stay in once it's rinsed out. After using it, my hair feels healthier, smoother, and just overall nicer to style.

Definitely leaves hair smooth
[This review was collected as part of a promotion.] I received this product in exchange for my honest review. I have tested this for about a month. The conditioner is not as heavy as other ones I have tried which is good so it’s doesn’t weigh down my long hair. I’m not sure on the long term benefits yet. I do think the smell is quite nice not too strong as I am sensitive to scents. The conditioner feels very lightweight and makes it easy to brush my hair out in the shower.

Softer more manageable hair
[This review was collected as part of a promotion.] The conditioner is rich but not heavy, which I love. It smooths out tangles instantly and leaves my hair soft, bouncy, and manageable without weighing it down. After rinsing, my hair feels nourished and silky, and it stays smooth even after blow-drying. The fragrance lingers just enough to make my hair smell amazing all day. Paired with the shampoo, this has really helped reduce breakage and made my hair feel healthier overall.

Good conditioner, waiting to see full potential
[This review was collected as part of a promotion.] I’ve been testing this out for about a month now and while my hair does look nice I haven’t yet noticed a huge difference in fall out. I do think there is less breakage and my hair looks to have leas fly aways than usual. It does leave my hair very soft and feels great.

Love this conditioner, lightweight and works!
[This review was collected as part of a promotion.] I love this conditioner by Kerastase! I have been using this product for about 6 months, and I really feel like it’s strengthened my hair. The texture of this conditioner is perfect, it’s creamy but fairly light weight and I feel like my hair sucks it all up! It also doesn’t leave a residue on your back like some conditioners causing acne etc. The scent is also great, and lasts for days! I do prefer the conditioner in this line over the shampoo but have been using them together. Overall I would recommend if you’re looking to strengthen your hair if you experience hair loss when washing and brushing!

Great conditioner for breakage prone hair
[This review was collected as part of a promotion.] I have extensions but used this on my real hair. I have very fine hair that is prone to breakage. Over the course of a couple weeks I noticed alot less shedding and breakage. It is pricey but worth it ! Smells amazing too . It didn’t make my hair greasy or oily at all.

[This review was collected as part of a promotion.] Omg this is the best conditioner I think I’ve ever used!! My initial impression was that it wasn’t anything special. The scent is nice, nothing notable. What really matters is the result. My hair has become thicker & more voluminous, others have even commented on it! My own mom had been mentioning how it was thinner than it used to be & after I started using this conditioner w/ the shampoo, she’s brought up how much thicker & healthier my hair has been looking!!

Easy to detangle after and so smooth!
[This review was collected as part of a promotion.] I paired this conditioner with the shampoo of the same line and was happy with how soft the two left my hair! The smell is pleasant and left my hair smooth immediately after use. It easily de tangled my hair, however I seemingly had to use much more product than I expected to. I think this could be attributed to the small opening for the conditioner to come out of. Overall though, I liked this product!

Get a flip top!
[This review was collected as part of a promotion.] [I received this product in exchange for my honest review] Clean scent and lathers nicely. I'm unsure if this has had any strengthening effect, however, almost 2 months into my postpartum journey, I haven't lost any hair yet and hair loss from my prior pregnancy has just started to recover, slow down to a halt, and my hair finally is starting to feel like itself again. I was happy with the results of this product. My hair felt clean and looked nice even without styling. I do absolutely find the packaging (the screw on caps) annoying 😑. They need to be flip tops. No one needs to use two hands to open a bottle and then need a place to put the cap while using the product and having to rescrew it back on.

My hair is smooth, soft, and hydrated after each use of this conditioner. The classic scent is gorgeous and lasts a long time! It’s almost like hair perfume. This is my new go to conditioner!

Lightweight, great for fine hair
[This review was collected as part of a promotion.] I’ve been using both the genesis shampoo and conditioner for the past month and I’m really liking it! First of all, it smells great— I’m not great at describing fragrances but it’s almost citrusy? It’s definitely a lightweight product, which is perfect for my very fine hair. I don’t find that it feels weighed down at all, but it still feels moisturized. But because of that, this might not work as well for someone with thicker hair. I can’t say that I’ve seen any noticeable changes in breakage or hair fall, but it hasn’t been that long since I’ve started using these, nor do I really expect my shampoo and conditioner to have that much of an effect, since I already use bond repair treatments. Overall, it’s a really nice product, but probably not something I’ll repurchase at this price point.

Lightweight, strengthening and smoothing
[This review was collected as part of a promotion.] The Genesis Fondant Renforçateur Conditioner is a total game-changer for anyone dealing with weakened, breakage-prone hair. I’ve always struggled to find a conditioner that gives deep nourishment without making my hair feel heavy or greasy—but this one nails it.
It has a silky, lightweight texture that glides through my hair effortlessly, instantly detangling and smoothing every strand. The moment I rinse it out, my hair feels stronger, more resilient, and unbelievably soft. And the scent? Heavenly. Just like the Genesis shampoo, it leaves your hair smelling fresh and luxurious for days.
What really sets this conditioner apart is how it strengthens my hair without sacrificing volume. My ends feel healthier, there’s noticeably less breakage when I brush or style, and my hair has a natural, healthy bounce to it. It’s the perfect balance of hydration and repair.
I’ve been pairing it with the Genesis Bain Hydra-Fortifiant Shampoo and the difference in my hair is unreal—less fall, more shine, and just overall better hair days. If you're on the fence, don’t be. This conditioner is absolutely worth it. A true staple in my haircare routine!

Hydrating and fragrant conditioner
[This review was collected as part of a promotion.] This conditioner is an excellent partner to the shampoo. I have a lot of thick hair and frequent dyeing and heat processing has definitely stripped some of the softness it used to have. This conditioner does a great job of giving my hair back that silky smooth feeling, without weighing it down. It (and the accompanying shampoo) is very fragrance-heavy so if you are sensitive, this may not be for you. Personally I really enjoy the scent (clean floralish) and wish it would linger longer post-shower.

Results with a side of baby powder?
[This review was collected as part of a promotion.] I was extremely excited to try the Kerastase shampoo and conditioner after reading so many good things, and while it performs the benefits it claims, theres pros and cons I've noticed. First off- the packaging. It's beautiful and modern, but having a twist cap loses points to me. With this conditioner, if you like your hair smelling like baby powder, this is the scent for you. Personally, I didn't care for the scent at all and would've preferred the conditioner to be either scentless or in a better scent. The conditioner helps smooth the hair down, but my hair doesn't feel soft as compared to other conditioners. This might be because of the anti-oil anti-breakage benefits? I've noticed that with this conditioner, however, my hair doesn't feel oily or slick compared to other conditioners. I've had less breakage, and I've noticed I can go an extra day or two between washes without my hair looking like a grease ball. Does it do as it advertises? Absolutely. There's just minor changes to the formula and packaging I'd make.

Hi siddy_732! Thank you for your detailed review of Genesis Fondant Renforçateur Conditioner. We're delighted to hear it delivered on its promises regarding reduced breakage and oiliness! We appreciate your honest feedback on the twist cap packaging design and will pass this feedback along to our design team. Fragrance preference is incredibly personal and your description is valuable to other consumers. Your observation about the hair's feel is insightful; this conditioner is formulated to provide lightweight reinforcement and oil control, which can result in a different texture compared to other conditioner formulas. For an alternative anti-breakage conditioner option with a different scent profile, you might consider Résistance Ciment Anti-Usure Conditioner. https://tinyurl.com/2dvz2n87 Your feedback is truly valuable and we thank you for being a Kérastase customer!
