Complete trio for damaged and colour-treated hair. This Redken Acidic Bonding Concentrate set includes Shampoo 300ml, Conditioner 300ml and 5‑Minute Liquid Hair Mask 250ml to help reduce breakage, protect colour and improve hair strength and resilience. Formulated with Citric Acid and a concentrated Conditioning Care Complex, the shampoo and conditioner balance pH to defend against the effects of colouring, lightening and heat styling. The 5‑minute mask (16% citric acid) delivers intensive bond repair, hydration and enhanced shine; use weekly or as needed for extra repair. Directions: use the shampoo and conditioner as a complete regimen; apply products to wet hair, rinse; for the mask, apply mid-lengths to ends, leave 5 minutes, then rinse. In case of eye contact rinse immediately.
