Product Description
While beneficial in moderation, excessive calcium levels can lead to a calcium overdose that exacerbates the damage in over-processed or bleached hair, resulting in dullness and increased susceptibility to breakage. This hair repair oil treatment offers a dual-action approach: its potent concentration of reparative and nurturing ingredients effectively seals split ends, strengthens hair fibers, and significantly diminishes the persistent dullness often associated with damaged hair.
The result is visibly stronger hair that boasts a remarkable 4 times increase in shine.*

To enhance the restructuring care for your damaged or over-processed hair, explore the advantages of the layering technique offered by Kérastase. Begin with the pre-shampoo treatment, Kérastase Première Pre-Shampoo Treatment, which prepares your hair for deep repair. Without rinsing off the concentré, apply Kérastase Première Repairing Shampoo for additional decalcifying and repairing benefits. Follow up with a Première Repairing Conditioner or Première Repairing Hair Mask to further nourish your hair, and complete the routine by styling with the leave-in Kérastase Première Hair Repair Oil for a final touch of rejuvenation and protection.

The Key to Effectively Reversing Persistent Hair Damage
Unveiling the culprit behind recurring damage—calcium. Damaged and porous hair absorbs 3 times more calcium from water compared to healthy hair, leading to an excess of calcium and long-lasting damage. With each exposure to water, calcium accumulates, infiltrating keratin chains and causing breakage, making hair rigid and dull.
The solution lies in an 8% pure acids concentration in the Kérastase Decalcifying Repairing Pre-Shampoo Treatment formula. Citric acid, an organic acid, works from core to surface, neutralising dullness and stiffness by freeing hair from calcium excess. Once calcium is eliminated, Glycine, an amino acid in this pre-shampoo treatment, deeply penetrates the inner layer of the hair, reconnecting broken links between keratin chains and significantly reducing hair breakage.
