Revitalize and detox damaged hair with Kérastase Première Decalcifying Pre-Shampoo Treatment. This dual-action formula combines 8% pure acids—like citric acid and wisteria extract—to remove calcium buildup from hard water while restoring strength and smoothness. Glycine deeply hydrates and helps reconnect internal hair fiber bridges to reduce breakage and dullness.
Leaves hair soft, shiny, and frizz-free—ideal for all hair types needing a reset from mineral overload and damage.
