The Science Behind the Results:
This isn't just another repair shampoo - it's Redken's most concentrated bonding system. The formula combines Citric Acid (which balances pH for optimal repair) with Bonding Care Complex (which targets and rebuilds the internal bonds that give hair its strength). Together, they work at the molecular level to repair damage you can see and damage you can't.
How to Use:
Apply shampoo to wet hair and massage into a rich lather. Rinse thoroughly. Follow with conditioner, concentrating on damaged mid-lengths and ends. Leave for 2-3 minutes, then rinse. For best results, use together as a complete bonding system.
Why Stylists Recommend This Duo:
Professional colorists and stylists trust Redken's Acidic Bonding Concentrate because it delivers visible results fast. The sulfate-free formula is gentle enough for daily use but powerful enough to repair even severely damaged hair. Plus, the 1000ml professional size means long-lasting repair at exceptional value.
Professional tip: For maximum repair, follow with Redken's Acidic Bonding Concentrate Leave-In Treatment (sold separately) on damp hair before styling.

Learn More About Acidic Bonding Concentrate pH-Balancing Shampoo
What does the Acidic Bonding Concentrate pH-Balancing Shampoo do for your hair?
The Acidic Bonding Concentrate pH-Balancing Shampoo strengthens, conditions and delivers protection for all hair types and textures. This repairing shampoo for damaged coloured hair provides colour fade protection for anyone with coloured hair, imparting alpha hydroxy acid and citric acid into the hair for reinforcement. To prevent damage that can come from hair styling, this repairing shampoo features an acidic pH to defend against colour, styling and even water damage.
Can you use Redken Acidic Bonding Concentrate pH-Balancing Shampoo every day?
A good benchmark for using the Redken Acidic Bonding Concentrate pH-Balancing Shampoo is twice a week, ideally following with Acidic Bonding Concentrate Conditioner and Leave-In Treatment. If you have colour-treated hair, twice a week allows enough time for your natural oil to travel along each strand. If you have thicker, curly or coily hair, oil may travel slower, consider using this shampoo for damaged coloured hair once a week. If your hair is fine, thin and straight, oil will travel quickly meaning twice a week may be optimal. Explore Redken's hair care products for fine hair.
