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!

Product Review — Amazing Product, Disappointing Pa

Product Review — Amazing Product, Disappointing Packaging I absolutely love this product. It is genuinely one of the best hair products I have ever used, and I am a very loyal customer. The quality of the product itself is exceptional, and I continue to purchase it even though it is quite expensive. That said, for a premium product at this price point, the packaging on the conditioner is extremely disappointing. The metallic coating on the cap peels and flakes off, leaving little pieces of metallic material in my shower and on my hands. As you can see from the photo, the cap deteriorates significantly with normal use. What makes this especially frustrating is that the rest of the brand’s packaging feels beautiful and high-end. I don’t understand why this particular cap or coating is being used on a product that is constantly exposed to water. This seems like a packaging/product-management issue that should be addressed. For a luxury hair-care brand charging premium prices, the packaging should perform at the same level as the product inside. Five stars for the conditioner itself. The packaging, however, needs to be redesigned.

Thank you so much for your loyal support and for sharing such thoughtful, constructive feedback with us. We are thrilled to hear that the formula itself remains exceptional and is among the best you've used! However, we completely agree with you regarding the packaging: a luxury product at this price point should deliver a flawless experience from the formula to the cap, and it is certainly disappointing to experience flaking from water exposure. We take packaging quality very seriously, and we are sharing your detailed review directly with our product development and quality teams so this can be addressed. Thank you for helping us elevate the Kérastase experience. If there is anything we can do to assist you further, please don't hesitate to reach out! 🤍

I noted an issue with dry hair, especially in the winter months and with my occasional saunas. Tried this product, and it helped a lot but everyday was more than I needed. I now alternate with Densifique Fondant Densité Conditioner, with the frequency depending on the season and how much moisterizing is needed. Works great!

Reply from Consumer Care Center 22/07/2026

We completely understand your perspective and appreciate your honest feedback. When you invest in a luxury Kérastase conditioner, you deserve a noticeable, extraordinary difference that makes the price feel entirely worthwhile. Because our professional conditioners are highly concentrated and designed to target the hair fiber deeply rather than just coating the surface, results can sometimes depend heavily on application. Using just a small, walnut-sized amount on well-towel-dried hair—and focusing strictly from mid-lengths to ends—allows the active ingredients to absorb fully rather than slipping off wet strands. We want you to feel the true, salon-grade transformation you paid for. If you would like to share your specific hair type and goals, our team would love to help you optimize your routine or find a formula that delivers the clear "wow" factor you deserve.

This is amazing !

Since I use your kerastase conditioner my hair looks glossy, shiny and very smooth. I don’t remember what is to have frizz. I love it, is a 100/10.

Expensive but worth it!!

[This review was collected as part of a promotion.] Best ever condition for fussy hair. Ni have tried all the best expensive conditions but I can never find one that gets my hair soft and shiney until I used Ketastase . My hair blow dries soft and smooth and I don’t need my straightening iron which has ruined my hair.

Best lightweight conditioner

[This review was collected as part of a promotion.] I have fine hair that gets weighed down easily. As someone who needs to wash her hair everyday, it’s the only conditioner that nourishes my hair without weighing it down.

Did not smooth my curly , coarse, hair.

Although I like the shampoo in this line, this conditiona did nothing to smooth my coarse, curly hair. It left it dry looking and kind of fly away.

Originaly posted on  kerastase-usa.com

Reply from Consumer Care Center 30/06/2026

We are so glad to hear that you enjoy the shampoo, but we are truly sorry that the conditioner did not deliver the smooth, defined results your coarse, curly hair deserves. Coarse curls have a naturally open cuticle that requires incredibly deep, lipid-rich nutrition to smooth down frizz and lock in moisture—benefits that a standard conditioner sometimes cannot fully provide. For your beautiful texture, we highly recommend swapping the conditioner for a rich, deeply nourishing masque (mask) from the same line once or twice a week, and sealing your curls with a leave-in cream or oil while they are still damp to prevent those dry-looking flyaways. If you would like to call our Client Concierge at 1-877-254-9949 (Mon–Fri, 9 AM–6 PM EST), we would be delighted to help you find the perfect rich masque or leave-in treatment to give your coarse curls the gorgeous, frizz-free definition they deserve. 🤍

Soft, smooth, and lightweight

I absolutely love this conditioner. It leaves my hair feeling incredibly soft, smooth, and hydrated without making it feel heavy. After using it, my hair is much easier to detangle and style, and it looks healthier and shinier. The texture is lightweight but still provides great moisture. It pairs perfectly with the Genesis shampoo, and together they make my hair feel stronger and more manageable. I would definitely repurchase it.

Good Conditioner

This conditioner is alright . I have 3b curly hair and it does make it softer but I definitely prefer the curly manifesto one.

Originaly posted on  kerastase-usa.com

Reply from Consumer Care Center 17/06/2026

We completely understand, and your 3b curls have excellent taste! There is a clear scientific reason for your preference. While our Première range is designed for structural calcium repair, curly hair naturally craves intense hydration and elasticity. Our Curl Manifesto range—infused with Manuka Honey and Ceramides—is specifically engineered to flood dry curls with weightless moisture, ease detangling, and enhance your ringlets' natural bounce and definition. It gives your curls the exact nourishment they need, which a standard repairing conditioner cannot match. We are so glad you found your perfect match in Curl Manifesto to keep your curls soft, bouncy, and beautifully defined!
