Sulfate-free, ultra-rich bonding shampoo powered by Redken’s most concentrated bonding care complex and citric acid to reinforce weakened bonds from within while gently cleansing.

Ideal for all types of damaged hair, it provides ultimate strength repair, intense conditioning, and color fade protection without stripping, leaving strands smoother, stronger, and vibrantly healthy-looking.

4. Follow with Redken Acidic Bonding Concentrate Conditioner, taking a 50-cent piece-sized amount.

5. Work it through your hair, concentrating on mid-lengths and ends.

6. Leave the conditioner on for a few minutes (1–3 minutes daily, or up to 5 for intensive repair).

Pro Tips

• For severely damaged hair, leave the conditioner on up to 5 minutes or pair with Redken Acidic Bonding Concentrate Intensive Pre-Treatment or Leave-In for deeper repair.
• Use cool water for the final rinse to further seal the cuticle, lock in moisture, and boost shine.
• Adjust amounts based on hair length/thickness – start small on fine hair to avoid weighing down while still strengthening.
• Combine with other Acidic Bonding products (like the mask or serum) for cumulative results and longer-lasting color vibrancy.
