Can I use it every day?

Yes, it is formulated as a daily shampoo for regular washing. Those with dry ends may prefer to alternate with a more moisturizing shampoo.

Does it work for oily scalps?

The formula is designed to limit oil buildup, and reviewers say hair stays fresh longer between washes. Results vary by scalp.

Do I need the Genesis conditioner and serum too?

Not required, but the line is designed to work together. Using a conditioner or serum helps if the shampoo leaves your ends dry.

No. It is a conventional foaming shampoo, so it is not the choice for shoppers avoiding sulfates.

Our take on the Kerastase Genesis Bain Hydra-Fortifiant Shampoo 8.5 oz

Kérastase Genesis Bain Hydra-Fortifiant is a daily shampoo from the brand's Genesis line for weak, fragile hair prone to breakage from brushing and heat styling. It cleanses the scalp and aims to reduce oil buildup while supporting stronger-feeling strands. It suits fine to medium hair that tangles or snaps easily and wants a lightweight daily wash. Against drugstore strengthening shampoos it is a premium salon formula; reviewers rate it well overall but some find it drying or say it did not stop shedding.
