Kérastase Pre-Shampoo Treatment Première Concentré Décalcifiant Ultra-Réparateur 1000 ml

Professional decalcifying and ultra-repairing treatment for damaged hair – Salon Size 1 Liter

The Kérastase Première Concentré Décalcifiant Ultra-Réparateur 1000 ml is the first pre-shampoo treatment formulated to remove excess calcium and deeply repair all types of damaged hair.

Calcium-rich water can further weaken treated or lightened hair. Because damaged hair is more porous, it absorbs more calcium than natural hair, becoming stiff, dull and fragile.

This professional treatment by Kérastase is selected and tested at Celebre Store salons, hairdressers spanning four generations since 1914.

What is the Concentré Décalcifiant Ultra-Réparateur

It is a high-concentration pre-shampoo treatment of pure acids with a dual action:

1. Decalcifies hair by removing excess calcium

2. Repairs from within by rebuilding broken bonds between keratin chains

The transparent gel texture works deeply, improving the stiff, dull appearance of hair and restoring strength, elasticity and shine.
