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.

Excellent product. Since I use it I notice less loss and my hair feels stronger and healthier. It doesn't leave hair greasy and smells very good. It's worth it. 💖

love this serum. It makes my hair feel stronger, softer, and reduces breakage within the first few weeks. It’s not greasy and absorbs quickly. The scent is light and pleasant. Perfect if you have weakened or thinning hair. I would definitely buy it again

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’ve been using the Kérastase Genesis Hair Serum for a few weeks, and I can already see a difference! My hair feels stronger, softer, and less prone to breakage. It has a light, pleasant scent and doesn’t leave my hair greasy. I love how it absorbs quickly and adds a healthy shine. Perfect for anyone struggling with hair fall or weak strands definitely worth it!

this hair serum actually works. escpecially if you have low porosity hair and does not get really greasy.

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.

I’ve been using the Kérastase Genesis Hair Serum for a while, and I’m really impressed. My hair feels stronger, smoother, and more manageable, and it looks healthier overall. The serum absorbs quickly, doesn’t leave a greasy residue, and adds a nice shine without weighing my hair down. I’ve also noticed reduced breakage and less frizz, which is a big plus. It’s a bit of an investment, but the results are noticeable and make it worth it if you want to protect your hair from damage while keeping it soft and sleek.
