the perfect partner to my favorite shampoo 👯♀️💘
[This review was collected as part of a promotion.] I had already been using the Kerastase Genesis conditioner for months before joining this campaign, so I was absolutely thrilled to be part of it. I love the fresh, sophisticated scent it leaves behind, and I’ve noticed a visible improvement in my hair’s strength and smoothness, despite my tendency to lose a lot of hair. The formula is rich yet lightweight, making it easy to detangle without weighing my hair down. While it’s not the most budget-friendly option, its effectiveness and the high-quality ingredients truly justify the price. For optimal results, I recommend using it alongside the Genesis shampoo and the heat protector from the same range.

Shiny and smooth hair!
[This review was collected as part of a promotion.] This Kerastase genesis conditioner has helped so much with my frizzy hair, dry split ends and the overall look of my hair! Ever since I started using it my hair has been very shiny, smooth, my split ends look less intense than they used to and overall my hair is easier to style. The scent is amazing and the packaging is great and easy to use. Overall recommend to anyone who is struggling with dry and damaged hair, as this conditioner will make a huge difference.

Good
[This review was collected as part of a promotion.] This conditioner feels like a high-end treat for my hair—rich, silky, and instantly smoothing. It leaves my strands soft, shiny, and easy to manage, with a lovely salon-like scent. The only drawback is the price, which feels a bit steep for the amount you get. Still, it delivers noticeable results and makes my hair feel healthier overall.

Light creamy conditioner that leaves hair soft, sh
[This review was collected as part of a promotion.] The Kerastase Genesis Fondant Renforçateur Conditioner makes my hair feel silky smooth and so easy to detangle. It has a light creamy texture that coats the hair without feeling heavy, and it rinses out cleanly. My hair feels nourished and soft but still light and bouncy. The scent is fresh and luxurious, and it lingers just enough without being overpowering. I love how my ends look healthier and shinier after using it, and paired with the shampoo it makes my hair feel like I just stepped out of a salon.

Feels salon like treatment after just one wash!!
[This review was collected as part of a promotion.] After one use, this conditioner has already made my hair feel silky, smooth, and easy to detangle. It’s lightweight yet nourishing, and the scent is gorgeous — just like a salon treatment. My hair feels softer and more manageable, and I’m excited to see even better results with continued use. Looking forward to seeing how it helps with breakage after a few more washes.

[This review was collected as part of a promotion.] I have oily scalp and dry ends with a LOT of split ends, so it has been a struggle for me to find a shampoo and conditioner that works. I also have long, thin hair. This conditioner made my hair look so soft and shiny, without weighing it down or making look greasy. The smell is sooo good! It’s light, but makes your hair smell “expensive”. Small amount is enough for my hair that’s below my hips.

Luxury Product
This conditioner is a lifesaver for fragile, thinning, or over-processed hair. It leaves my strands noticeably stronger, softer, and smoother — without any heavy residue. Perfect for mid-length to long hair that breaks easily or gets weighed down.
The scent is luxurious (classic Kérastase), and it instantly detangles while reinforcing the hair fiber. If your ends snap easily or feel dry but you want body and movement — this is worth every penny.

Un excellent soin léger mais efficace
J’ai beaucoup aimé ce revitalisant. Il laisse les cheveux doux, légers et faciles à démêler, sans les alourdir. Dès les premières utilisations, j’ai remarqué moins de casse et mes longueurs semblent plus fortes.
L’odeur est douce et agréable, typique de Kérastase. En combinaison avec le shampoing de la même gamme, c’est une valeur sûre si vous cherchez à fortifier vos cheveux tout en gardant un bel aspect souple et soyeux.
Je le recommande sans hésitation!

A Game-Changer for Weak, Breakage-Prone Hair
A Game-Changer for Weak, Breakage-Prone Hair!
I've been using the Kérastase Genesis Fondant Renforçateur Conditioner for a few weeks now, and the difference in my hair is undeniable. My hair was feeling fragile and prone to breakage, especially after heat styling and environmental stress. This conditioner has been a total game-changer.
From the first use, my hair felt noticeably smoother, softer, and more manageable. It detangles effortlessly, which is a huge plus for anyone with longer hair prone to knots. Despite being deeply nourishing, it's incredibly lightweight — it doesn’t weigh my hair down or leave it feeling greasy, which is rare for strengthening conditioners.
The scent is luxurious and salon-quality, which makes every wash feel like a pampering experience. Most importantly, I’ve seen a visible reduction in hair fall due to breakage. My strands feel stronger, healthier, and more resilient.
If you're dealing with weak or brittle hair, this conditioner is absolutely worth the investment. It’s effective, elegant, and lives up to the high standards Kérastase is known for.
Highly recommend! 🌟
I've been using the Kérastase Genesis Fondant Renforçateur Conditioner for a few weeks now, and the difference in my hair is undeniable. My hair was feeling fragile and prone to breakage, especially after heat styling and environmental stress. This conditioner has been a total game-changer.
From the first use, my hair felt noticeably smoother, softer, and more manageable. It detangles effortlessly, which is a huge plus for anyone with longer hair prone to knots. Despite being deeply nourishing, it's incredibly lightweight — it doesn’t weigh my hair down or leave it feeling greasy, which is rare for strengthening conditioners.
The scent is luxurious and salon-quality, which makes every wash feel like a pampering experience. Most importantly, I’ve seen a visible reduction in hair fall due to breakage. My strands feel stronger, healthier, and more resilient.
If you're dealing with weak or brittle hair, this conditioner is absolutely worth the investment. It’s effective, elegant, and lives up to the high standards Kérastase is known for.
Highly recommend! 🌟

Meh
[This review was collected as part of a promotion.] It smells really nice! My only issue is that it says you have to towel dry your hair, THEN put it in your hair, wait 3-4 mins and then rinse out. I'm a busy working mom that barely has time to shower as is. Drying my hair and then doing this isn't feasible for my lifestyle.

Very helpful but not for thick hair
[This review was collected as part of a promotion.] I love this product but I have very thick hair and it takes a lot of the conditioner to properly condition in one sitting. The conditioner seems to disappear into my hair and I have to use quite a bit to get it spread somewhat evenly. If you have thick hair try the other conditioners.
