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

The Kérastase growth serum has honestly been a really good addition to my hair care routine. I started using it because I wanted to reduce hair fall and help my hair feel stronger and healthier over time. What I noticed first is that the serum is very lightweight and doesn’t make my scalp greasy, which makes it easy to apply daily or at night. It absorbs quickly and doesn’t leave any heavy or sticky feeling. After a few weeks of consistent use, my hair felt stronger and I noticed less breakage when brushing. I also started seeing small baby hairs, which made me feel like my scalp was actually responding well to the treatment. The scent is soft and luxurious, like most Kérastase products, and it makes the routine feel more like a self-care moment. The only downside is the price—it’s definitely an investment, but you don’t need a lot of product each time, so it lasts a while. Overall, it’s a great serum if you’re dealing with weak, thinning, or breakage-prone hair and want something that supports healthier growth over time.

This serum is a game changer for weak or thinning hair. It’s very lightweight and absorbs quickly without leaving any greasy feeling. I love the dropper because it makes application easy and precise directly on the scalp. After consistent use, I noticed less hair fall and my hair feels stronger and healthier. It also smells amazing and fits perfectly into my daily routine. Definitely worth it!

I’ve been using the Kerastase Genesis Hair Serum – Daily Strengthening Treatment for a few weeks now, and the results are incredible. This serum has truly strengthened my weak, damaged hair and given it a noticeably healthier look and feel. The texture is lightweight and absorbs instantly without any greasy residue. I use it daily, and it nourishes my hair from root to tip while helping reduce breakage. My hair feels stronger, smoother, and more resilient — even on days after heat styling. I also love that it’s easy to use and doesn’t weigh my hair down. A little goes a long way, and the results speak for themselves. If your hair is fragile, prone to breakage, or just needs a boost of nourishment, this serum is definitely worth trying! Highly recommend!

I’m currently on my second bottle, and this serum truly delivers results. With consistent use, I’ve noticed reduced hair fall and stronger, healthier-looking hair. The texture is lightweight, and the scent is amazing. Highly recommend!

Man oh man! Finally something that actually helps! When I say my shedding is almost non-existent, I mean it. I would brush my hair or when I’m washing my hair, chunks of hair would come out. Now? A few strands here and there. My hair feels thicker and so much more healthier! Zero greasiness, great smell and over all just amazing! I have recommended this product to everyone I know! This will forever be a repurchase for me! Thanks kerastase!

I’m not sure if this was the sole reason my little hair patch grew back as I used cécred as well. However, it does amazing work. Will repurchase!

This product really helped with my hair loss. I followed the treatment for 6 weeks as recommended and started noticing a difference within the first week. By the end of the treatment, I only had a few strands of hair falling out, which is normal. I’m giving it 4 stars because after stopping for a month, my hair started falling out again. It seems you have to use it consistently to maintain results. Since the product is a bit pricey, that’s something to keep in mind. I was hoping for longer-lasting effects, but overall, it did work while I was using it. I’ll keep searching for something with more permanent results.

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

Ausgezeichnetes Haarprodukt, uneingeschränkt empfehlenswert

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.
