Will repurchase again and again!
[I received this product in exchange for my honest review] I have fine hair and i loved that this shampoo gave extra volume without weighing the hair down. It has a really nice scent and the formula is very gentle. My only wish would be a pump rather than the way they have it for easier dispensing, but that’s okay. I’ve been using this product for the past month as my second wash for shampoo as my hair gets very weighed down easily and it’s been such a great addition to my routine!

Smells amazing!!
[I received this product in exchange for my honest review] The smell is amazing. Does it work on curly frizzy hair—I’d say no. The conditioner was empty fairly quickly. It did end up drying my hair out a little but it was great to try.

Love this product!
[I received this product in exchange for my honest review] I received the Kérastase Genesis Bain Hydra-Fortifiant Shampoo for free in exchange for my honest review, and I absolutely love it! It’s become part of my regular haircare rotation. It leaves my hair feeling clean, soft, and lightweight — and I’ve noticed I can go longer between washes, which is a huge plus. The only downside is that it doesn’t do much for volume on my flatter hair, but the overall results make up for it. My hair feels stronger, looks healthier, and stays fresher longer. Definitely a win for anyone with oily or weakened hair!
