A clarifying shampoo from Kérastase's Première line, built around citric acid and glycine to strip calcium and product build-up from hair while limiting the look of breakage. It comes in a 500 mL refillable bottle that takes a refill pouch, so the packaging is meant to be reused. It suits adults with damaged, dry or hard-water-affected hair who want a clarifying wash that still feels repairing rather than stripping. Against drugstore clarifiers it is gentler and more conditioning; against Kérastase's own Repair or Nutritive ranges it is the detox step, not a daily moisturizing shampoo.

Owners of the Première line generally praise how clean hair feels after washing out hard-water build-up, and many say hair looks less dry and snaps less. Criticism centers on the clarifying formula being too stripping for frequent use and on the strong fragrance.
Kérastase Première Bain Décalcifiant Réparateur is a clarifying shampoo for damaged hair. It works against calcium in shower water and rinses away build-up. It also reduces the appearance of dryness.
Citric acid cleanses away impurities and excess oil. Glycine helps visibly repair hair and reduce breakage. The bottle is refillable and can be topped up from a refill pouch.
Apply to wet hair, massage and emulsify, then rinse thoroughly. Use it after the Decalcifying Repairing Pre-Shampoo Treatment, and follow with Première Conditioner.
