Add the Redken Extreme Duo (2 Products) shampoo and conditioner set to your daily routine and enjoy the deeply restorative impact it has on over-worked, damaged hair. These complementary products work together to replenish and nourish dry, brittle hair while delivering an intense and thorough cleanse. The shampoo contains Salicylic Acid, which gently exfoliates and soothes the scalp, while smoothing the hair follicles. Added to this, Hydrolyzed Soy Protein moisturises the hair, and delivers anti-static and conditioning ingredients. The conditioner then mirrors these effects, while infusing the hair with a moisturising and smoothing boost - working further to detangle and repair each hair shaft. Daily use of the protein-enriched Redken Extreme Duo (2 Products) will increase the vitality of previously damaged hair, leaving behind a healthier, regenerated appearance. Its intuitive technology harnesses and enhances the natural shine of the hair, while reducing split ends. Once the shampoo has worked its wonders, the conditioner adds a protective effect to the hair, helping to prevent breakage, and allowing the hair to achieve its full potential in excellent condition.
