Hydration without heaviness. Smell great
Deeply Nourishing Leaves hair very soft and smooth after use. The texture is rich but doesn’t weigh the hair down. It smells luxurious and helps improve manageability.

Love Kerastase
This stuff is amazing - if nothing else for the smell. The smell is strong, so if you are sensitive to that, then this isn't for you. Hair feels so soft for a couple of days after use. Kerastase products are all great, this one is no different

Kerastase Shampoo and Conditioner
I’ve been using this shampoo and conditioner for a few weeks now, and I’m very impressed. My hair feels cleaner, softer, and much more manageable. It doesn’t leave my hair heavy or greasy, and the scent is light and pleasant. I’ve noticed less frizz and more shine since I started using it. Definitely a great product and I will continue to repurchase!💖💖💖💖 ... show more
