This conditioner is great to pair with the shampoo. It definitely strengths your hair and adds shine and softness as well too. There is minimal breakage after using both products. If you get the shampoo, I definitely recommend buying the conditioner as well in order to strengthen your hair and make it less prone to breakage. Beautiful conditioner!

Fragance not for me
[This review was collected as part of a promotion.] The formula itself is good. The cream has a lovely richness to it and it leaves my hair feeling incredibly smooth and conditioned. When it comes to performance, it does a great job.
However, I have realized that the signature Genesis fragrance is just not for me. To be fair, the scent in this conditioner is not as strong or overwhelming as it is in the serum from the same line, but it is still a specific smell that I do not love. If you enjoy the Genesis scent, you will love this, but I will be looking for a different line next time.

Nice scent & works well so far
[This review was collected as part of a promotion.] This conditioner pairs well with the matching shampoo. The scent is lovely and the conditioner consistency is thick which has worked well so far for my dry ends. Still on the pricey end which is why I can’t get myself to rate 5 stars, but I do feel like conditioner lasts me a little longer so hopefully it’s worth it in the end.

Hi there! 💜 We completely understand—when a formula feels a bit too protein-heavy or doesn't quite hit the mark for specific concerns like hair fall, it can be a bit disappointing, even if the weightlessness was a nice touch for your fine hair! We truly appreciate you taking our quiz and sharing your honest feedback with us so we can always improve. Thank you! ✨

Love!!!
Similar to the shampoo, you need such a tiny amount to make your hair soft. It doesn’t feel like there’s anything on your hair and it doesn’t make your hair feel slippery like other conditioners do, but when you wash it out.. your hair feels SO soft!!! I love how silky my hair looks when I blow dry it. Also, even though I don’t condition my scalp, most make my hair oily by the next day. With this shampoo and conditioner, I can go 2-3 days between washes.

Good!
[This review was collected as part of a promotion.] The quality of my hair is not good, it'svery weak. I decided to purchase Genesis to stop loose it didn't help immediately, but after 2-3 weeks I felt the difference, my hair became stronger and more healthy.

Beautiful
[This review was collected as part of a promotion.] The experience of using the Genesis conditioner after the shampoo is wonderful. I’m dealing with breakage from coloring and was trying so many things to help but plan to stick with Genesis for a while. My hair and scalp feel clean but also soothed and smooth.

Stronger hair
[This review was collected as part of a promotion.] The Genesis Fondant Renforçateur Conditioner leaves my hair feeling soft, smooth, and noticeably stronger. It helps reduce breakage and makes my hair easier to detangle without weighing it down. A great choice for dry or fragile hair!

Pretty good but overpriced
This is moisturizing but not worth the money, it’s a good product but the price is set too high for what it delivers.

Another great product
My hair feels so soft & doesn't weigh down my soft curls when drying naturally.

Souplesse et douceur des cheveux
J’emploie le bain hydratant fortifiant K Genesis ainsi que fondant renforçateur K Genesis seulement depuis environ 3 semaines . Je constate que mes cheveux sont plus souples et soyeux .J’espère qu’avec le temps j’aurai moins de perte de cheveux .

Thinning hair and hair loss
[This review was collected as part of a promotion.] I started using this shampoo and complimenting conditioner because my hair was thinning and falling out due to my GLP1 shot. I also started taking a few vitamins and having my protein. My hair is no longer falling out or shedding as bad and is starting to fill in again. I think this shampoo and conditioner definitely helped!

Perfect light conditioning for daily use
[This review was collected as part of a promotion.] This is the perfect conditioner for daily use if you are experiencing hair loss. It has helped me tremendously and if I stop using it I can tell a difference.
