    • Holy grail for dry / weak hair
Size: 8.5 Fl Oz (Pack of 1)
5th time buying! Best shampoo I've tried for dry, weak hair prone to breakage. Cleans scalp well without stripping, leaves hair soft, hydrated and much less breakage. Smells luxurious. Expensive but lasts and works. Will keep repurchasing!

    • LOVE this product!
Size: 8.5 Fl Oz (Pack of 1)
Stronger, Softer Hair Starts Here – A True Salon Experience at Home! I’ve been using Kérastase Genesis Shampoo for a few weeks now, and I can confidently say—it’s a game-changer. My hair has never felt this strong, soft, and healthy, especially considering how much it’s been through with heat styling and seasonal shedding. From the first wash, I noticed a difference. The texture is luxuriously creamy, and a little goes a long way. It lathers beautifully and rinses clean without leaving any residue. The scent is subtle yet elegant—like something you’d expect in a high-end salon—and it lingers just enough to make your hair feel freshly washed all day. What really sets this shampoo apart is how it targets hair fall due to breakage. After consistent use, I’ve seen noticeably less hair in the drain and on my brush. My strands feel stronger, smoother, and more resilient. It’s also gentle on the scalp, leaving it feeling clean and balanced without any dryness or irritation. ✅ Strengthens and reduces breakage ✅ Leaves hair soft, shiny, and manageable ✅ Beautiful, salon-quality scent ✅ Worth the investment for healthier hair If you’re dealing with hair fall or just want to give your hair a little extra love, this shampoo is absolutely worth it. Pair it with the Genesis conditioner or serum for even better results. I’m officially hooked! ... show more

    • makes my hair so soft
Size: 8.5 Fl Oz (Pack of 1)
Love how this shampoo makes my hair so soft, and the fragrance is amazing! The scent lasts for a couple of days, which I really love. It leaves my hair feeling clean, soft, and smelling wonderful. Definitely a favorite!

    • A very good purchase!!!
Size: 8.5 Fl Oz (Pack of 1)
This shampoo is great, it leaves a softness in the hair, smells too rich and above all stops the fall in the first wash, super recommended

    • Hair type + price
Size: 8.5 Fl Oz (Pack of 1)
I saw this shampoo on tiktok and wanted to try it out. I’ve used it for a couple days now and I’ve already seen a difference. My hair feels cleaner and silky smooth. The only bad thing is the price is so expensive for what you get and you’ll run out fast. My hair is naturally wavy and this shampoo will make your hair flatter, so I do not recommend for curly hair. I also have naturally thick and easily greasy hair and this makes my hair look so much nicer. The smell is strong, not bad, but definitely strong so some people may not like that about it either, but it doesn’t bother me much. There isn’t one universal shampoo that will work for everyone, but I highly recommend. ... show more

I’ve been happy with this shampoo so far. It cleans my hair well without making it feel dry. My hair feels softer and stronger after using it, and I like the scent. A bit expensive, but the quality is very good.

Always leaves my hair softer then I thought possible. I always get the hair mask and conditioner that jives with the shampoo choice. Top of the line product would recommend to all my friends
