LOVE this product!
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 hairIf 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!

High-Quality Shampoo That Delivers Noticeable Results
I’ve been using this shampoo for a few weeks now, and I’m genuinely impressed. A small amount goes a long way—it lathers beautifully and rinses out easily. My hair feels noticeably softer and looks shinier after each wash. I have dry, breakage-prone hair, and this has helped reduce tangling and made my hair feel stronger overall. The scent is light and pleasant, and the bottle looks and feels luxurious. Definitely a great choice if your hair needs extra care and strength.

Great Shampoo
A homesite drop lather’s so much! Hair is soft and silky.
Amazon Customer –
Will continue to repurchase
Very silky and luxurious, lathers beautifully. Smells luxurious and cleans the hair without feeling stripped, felt gentle enough to use even with daily washing. Hair feels soft after styling. I feel it promotes less breakage and hair felt more elastic when brushing. Finished the bottle and will repurchase, despite the high end price

Just love the outcome in my hair has strengthened since I’ve been using it
I love this product for my weekend Hair. I’ve definitely noticed a change. It is a beautiful light smell without being overstrong. It is lightweight and you definitely do not need a lot to penetrate your scalp.

Siento mi pelo liviano, libre de peso que se añade con otros productos, lo siento libre, y que está cumpliendo con su función/anticaida por ruptura la fibra es pronto para decir que este forticiandose, hoy me llegó la mascarilla y esta semana el serum, más adelante haré mi comentario de resultados. De momento espectacular este producto y su olor!Recomiendo un puff de dispensador o muy poco. Hace mucha espuma que limpia a fondo. No necesitas un montón de producto!!
