A two-step set for hair weakened by bleach, color or heat: a clear gel pre-shampoo treatment and a creamy shampoo, both built around citric acid and glycine to strip excess calcium left by hard water. The idea is that porous, over-processed hair grabs calcium, which makes it stiff and dull, and decalcifying first lets the repair ingredients work. It suits people with chemically treated or hard-water-stressed hair who already follow a wash-day routine. Against ordinary repairing shampoos, the extra pre-shampoo step is the differentiator; against Kérastase's own Résistance line, it targets mineral buildup rather than breakage alone.

Owners of bleached and color-treated hair generally report softer, less stiff hair after several weeks, with the pre-shampoo step doing most of the work. Critics say the routine is fussy and results come slowly.
The Kérastase Première Decalcifying Repairing Duo pairs a pre-shampoo treatment with a shampoo. It is made for over-processed or bleached hair and targets calcium buildup from hard water. Damaged hair is more porous and more prone to calcium overload, which can cause stiffness, dullness and further weakening.
The formula uses pure citric acid and glycine to gently decalcify hair and visibly repair damage. The pre-shampoo is a transparent gel that removes excess calcium and prepares hair for cleansing. It is used before shampooing and helps repair damage from heat styling, color treatments, bleaching and over-processing.
The shampoo has a creamy formula that turns into a rich foam. It cleanses, removes calcium buildup, and smooths and nourishes hair. It is suitable for all hair types and leaves hair softer, shinier, more manageable and less prone to breakage.
