Premiere Decalcifying Resurfacing Concentrate Treatment

Kerastase's Premiere Decalcifying Resurfacing Concentrate Treatment is a pre-shampoo concentrate that helps remove hard-water calcium build-up, leaving hair feeling cleaner, softer, and more resilient. Powered by 2% citric acid and glycine within an 8% blend of pure acids, plus wisteria extract, it targets mineral deposits to support weakened fiber, improve strength, and restore a healthier-looking shine. As the formula works, hair looks smoother, feels easier to detangle, and styles with less effort, making it a practical reset for strands dulled or roughened by mineral overload. It suits all types of damaged hair affected by calcium overdose and leaves a bright, fresh scent of citrus, mandarin, orange blossom, and jasmine, while the cruelty-free formula is packaged in a bottle made from 95% recycled plastic.
