Kérastase's revolutionary Première Intensive Repairing Concentrate is the first of its kind, specially formulated to remove excess calcium and effectively repair damaged hair. Delicate hair types such as over-processed or bleached hair are more prone to calcium absorption, leading to further damage. This pre-wash glycine hair treatment utilises a potent concentration of 8% pure acids, decalcifying hair from the inside out. The transparent gel-like texture in this Intensive Repairing Concentrate works wonders in reconnecting broken keratin links, reinforcing hair strength, and transforming it from rigid and dull to resilient, healthy-looking, and shinier

How to use 

Step 1: Generously apply the Kérastase Première Intensive Repairing Concentrate to damp hair before shampooing, massaging it thoroughly from roots to ends.
Step 2: Allow the Intensive Repairing Concentrate to sit for 5 minutes.
Step 3: Without rinsing, apply the Première Decalcifying & Repairing Shampoo directly on top.
Step 4: Follow with Première Repairing Conditioner for Damaged Hair for optimal effectiveness.
