The Kérastase Decalcifying Repairing Conditioner helps to remove excess calcium and visibly repair all types of damaged hair. Designed for hair damaged by heat tools, colour treatment, bleaching and over-processing, the conditioner works to recreate hair’s natural movement and bounce when used as part of the Première routine. When hair is already damaged, excess calcium will accumulate, further weakening the cuticle and cortex of the hair. The dual-action formula works to remove calcium from the hair caused by hard ward, helping to defend against future breakage. With a lightweight, jelly-like texture, the conditioner leaves hair feeling soft, supple and up to 7x smoother*. *Instrumental test
