Is this the same as the old Bain Régénérant?

It is sold as the new Bain Régénérant under the Chronologiste line, with hyaluronic acid as the key ingredient. Treat it as the current version of Kérastase's repairing shampoo rather than a separate product.

It is made for weak, fragile or damaged hair that needs gentle cleansing plus nourishment. Normal or oily hair with no damage has little to gain from it.

Does it replace a conditioner or mask?

No. It is a shampoo, so damaged hair still needs a conditioner or mask afterward for detangling and lasting softness.

How often can I wash with it?

The formula is gentle enough for regular use. How often you wash depends on your scalp, not the shampoo.

One 250 ml (8.5 oz) bottle of Kérastase Bain Régénérant shampoo.
