Kerastase Genesis Hair Serum | Daily Strengthening Treatment for Weak or Damaged Hair | Nourishes and Reinforces Hair | Anti-Breakage | Silicone-Free | For Weakened Hair | Serum Fortifiant

I love everything about this product! Pricey but sooooooo worth it!!!! Used as directed and within the first week I started noticing a difference. My hair is softer, way less breakage, hair looks healthier, helped the hair growth. Smells really good too. I wish I would’ve taken before and after pictures.

Stronger Hair Starts at the Root – A Must-Have for Anyone Experiencing Hair Fall I’ve been using the Kérastase Genesis Hair Serum for just over a month, and the results have been nothing short of amazing. As someone who struggles with hair fall due to breakage, I was looking for something that could strengthen my hair without weighing it down—and this serum delivered on every front. The formula is lightweight and non-greasy, which makes it perfect for daily use. I apply it to my scalp after towel-drying my hair, and it absorbs quickly without leaving any residue. The scent is subtle and fresh—just enough to feel luxurious without being overpowering. What really impressed me is how noticeably stronger and healthier my hair feels. After consistent use, I’ve seen a significant reduction in hair fall when brushing or styling. My scalp feels more balanced, and my hair looks fuller and more resilient. ✅ Reduces breakage-related hair fall ✅ Lightweight, silicone-free formula ✅ Easy to apply and absorbs quickly ✅ Strengthens and nourishes from the root If you’re dealing with weakened or thinning hair, this serum is absolutely worth the investment. It’s a salon-quality treatment you can use at home—and it truly makes a difference. I’ll definitely be repurchasing!

We have only been using this for a few weeks and can already tell a difference in the texture of my hair. There is growth and is fuller to touch. The bottle itself is such larger than I thought and you only need a bit a day. It makes my hair look shiny and healthy for sure. I love the quality of product and can tell that my hair is getting thicker already!

My Haircare Holy Grail! I’ve been using this product for years now and it continues to impress me. It has a lightweight almost waterlike consistency that makes it easy to apply after every wash. One bottle usually lasts me a few months though you might run out faster with daily use. The fragrance is a bit strong for my liking but the results make up for it. The U.S. version doesn’t contain aminexil though it still works wonderfully. While I can’t say much about actual hair growth I’ve definitely noticed less hair fall since I started using it. I usually pair it with the Kerastase 8H Overnight Serum. Definitely worth giving it a try

I’m not usually the type of person who writes reviews for products I order, but I really wanted to share my honest experience. Postpartum completely damaged my hair, and I was desperate to find something that actually worked. I tried Nutrafol and took it consistently for three months, but nothing changed. It felt like a waste of both time and money—and honestly, I hated the taste too. If you’re thinking about trying argan oil, rosemary oil, or any of those “magic” hair growth oils, I’ll say this: if you’re prone to oily roots like I am, you’re probably not going to like them. I hate the feeling of oily roots, so putting oil on my scalp was never something I could stick with. I’m currently on my second bottle of this serum, and when my sister asked me, “What are you doing to your hair?” I went back and looked at my before-and-after photos. I was shocked—I didn’t even realize how much new hair growth I had. My hair looks so much denser, healthier, and thicker, and it smells soooo good. I’m obsessed with the scent, and I’ve been getting so many compliments. I use it almost every day, and one bottle lasts me about a month and a half. It is a bit pricey, but I’m honestly tired of wasting money on random $20–$30 products that don’t work. I will always recommend this product to every girl I know. I comment under posts, reels—anything about hair treatments—and recommend this product to anyone.

I have never felt compelled to write a review before, but this product has made me have a change of heart. Bottom line, this hair serum works and delivers everything as promised. I have always been insecure about my hair line framing the edges of my forehead; I believe the cause is from years of wearing tight hair-dos for sports, every day styles, etc. I purchased this serum before my wedding in October and have been absolutely blown away by the results. I can see noticeable growth in the areas of concern and can feel a major difference in the texture of my hair, thickness, and even length. I've also noticed a significant reduction in hair breakage around my face and an increase in shine! I have been getting compliments about how healthy my hair looks! I was a little hesitant about the price, and the $60+ price is the reason I'm giving this a 4/5, but would now recommend this to anyone looking to restore hair growth or wanting to improve overall hair health. Stay consistent with the application and you will see some serious results!

This smells so good and doesn’t leave your hair greasy. I do feel it’s made my hair healthier overall!

I had hair fall out 6 months ago , I saw a lot of YouTube blogger recommend this hair serum ! Honestly, it doesnot work for me ! I donot see it help with hair fall out , but it does make my hair very shiny ! Smooth ! It smells good and not oily ! But not for my hair type since I wants my hair not to keep falling , it doesn’t do much for that! But I think if you try to daily maintain your hair quality, you can try it! Still good product! But kind of pricey and doesnot last very long !

رائع

È un prodotto ottimo, mantiene le promesse. Effettivamente ho notato l' effetto di miglioramento sulla caduta dei capelli

J'ai acheté la gamme entière de cette marque pour un problème de chute de cheveux anormale. Le shampoing, l'après shampoing et ici le sérum. C'est un peu plus contraignant car il faut mettre ce sérum grâce à une pipette sur le cuir chevelu, raie par raies tous les matins ou soir au choix. J'ai pu constater au bout d'un mois une nette amélioration sur ma chute des cheveux mais j'utilise la gamme entière. Il y a des résultats assez significatifs. C'est une gamme assez chère mais c'est plus un soin anti chute qu'une gamme pour la brillance ou la couleur. Le sérum se présente dans un flacon en verre avec une pipette pour mieux répartir le produit sur le cuir chevelu. En l'utilisant tous les soirs depuis un bon mois il m'en reste encore. Il faut bien l'appliquer sur l'ensemble du crâne et masser. Ne pas utiliser sur les cheveux sinon ça risque de coller un peu. Pour ce sérum je dirais qu'il a amélioré mon problème. Je valide. Bon rapport qualité prix. Livré rapidement dans une boîte en carton et arrivé sans cassé. Parfait pour moi.

Purtroppo il prodotto è arrivato con l ampolla spaccata ed è fuoriuscito il siero

Ce produit est bien et facilite, en plus de la repousse, le coiffage
