How To Use:
Step 1 — Decalcify & Repair At The Core:
Wet hair and separate into 4 sections. Apply 15-25ml (4-5 pumps) with a brush. Leave in for 5 minutes — do not rinse. Layer directly on top with Kérastase Première Decalcifying Shampoo (10-15ml). Massage until hair becomes soft and smooth then rinse thoroughly and towel dry.
Step 2 — Decalcify & Repair At The Surface:
Separate hair into 4 parts. Apply 15-25ml Decalcifying Resurfacing Concentrate strand by strand on lengths. Massage — do not rinse. Apply 15-30ml Anti-Breakage Repairing Filler Mask on top with a brush, strand by strand. Massage and twist each strand. Leave in for 10 minutes then rinse thoroughly and towel dry.
Step 3 — Finish:
Apply Repairing Anti-Frizz Filler Serum to towel-dried lengths and ends. Heat protects up to 230°C. Blow-dry. Do not rinse. Finish with a few drops of Intensive Shine Repairing Oil on lengths and split ends.
Why Calcium Build-Up Damages Hair:
Hard water — which affects the majority of UK homes — contains high levels of calcium and magnesium minerals. Over time these minerals accumulate inside the hair structure, making hair feel rough, brittle and difficult to style while significantly reducing shine and strength. Standard shampoos cannot remove this internal calcium build-up. Kérastase Première is the first professional treatment specifically designed to decalcify the hair from within — removing years of mineral build-up to restore hair to its original, healthy strength.
