Kérastase Premiere Routine

The Kérastase Première Routine Set is designed for fine to medium-damaged hair and focuses on removing limescale and restoring structure. Limescale deposits from water can accumulate between keratin chains, weakening hair bonds and leading to stiffness, brittleness, and breakage. This comprehensive set includes a pre-shampoo concentrate, shampoo, conditioner, leave-in serum, and finishing oil, which work synergistically to eliminate limescale deposits and detoxify the hair from minerals. The pre-shampoo concentrate is applied before shampooing and contains active ingredients like citric acid and glycine that penetrate multiple layers of hair to dissolve limescale. The subsequent application of shampoo and conditioner helps restore the hair's original strength and manageability. Instrumental tests show 93 percent less hair breakage and 75 percent more shine after a single application of the concentrate, with hair exhibiting 99 percent increased strength after six applications of the complete routine. The leave-in serum provides thermal protection during styling, while the finishing oil enhances shine and smoothness. This systematic approach addresses the root cause of hair damage from hard water, neutralizes dullness and stiffness, and improves overall hair health. The products are formulated to complement each other, with the pre-treatment creating optimal conditions for subsequent products to deliver maximum benefits. For best results, apply the pre-shampoo to wet hair, leave it on for five minutes without rinsing, then apply shampoo, thoroughly massage, and rinse. Next, apply the conditioner, leave it on for several minutes, and rinse completely. Finally, use the leave-in serum before styling and the shine-enhancing oil as the last step.
