Set includes Redken Acidic Bonding Concentrate Shampoo 300ml, Conditioner 300ml and 24/7 Night & Day Serum 100ml. Designed for damaged and colour‑treated hair, the shampoo and conditioner use a concentrated bonding complex with citric acid to balance pH, deeply condition, reduce breakage and help protect colour and strength after colouring or lightening. The lightweight leave‑in serum combines polyglutamic acid and squalane to penetrate multiple layers, magnetise to the fibre and help repair and shield hair day and night. Reported benefits include up to 89% less breakage, 3x softer and 11x shinier hair. Fragrance blends citrus and lavender. How to use: shampoo, lather and rinse, then apply conditioner to wet hair and rinse. Apply 2 pumps of serum to mid-lengths and ends on damp hair for styling or on dry hair as an overnight treatment. In case of eye contact, rinse immediately.
