Your hair feels stronger, smoother, and less breakable after use. That’s because the Bonding Care Complex helps restore your hair’s weakened structure from within. Damaged hair often has a high pH, leaving the outer layer open and moisture escaping. Citric acid restores pH to a healthy level, sealing the cuticles so your hair is less frizzy and easier to style.

The shampoo gently cleanses with its sulphate-free formula, and the conditioner finishes the treatment with silicones that leave your hair smooth and protected. If you regularly bleach or colour, you’ll notice your hair feels less straw-like and your colour looks brighter after just a few weeks. The Redken Acidic Bonding Concentrate line provides a complete system that works every wash.

Yes, the Redken Acidic Bonding Concentrate line is specially developed for coloured and chemically treated hair. The formula helps slow colour fading, keeping your colour vibrant for longer.

The low pH shampoo seals the cuticles after washing, exactly what coloured hair needs. Colour molecules stay longer inside the hair shaft. Whether you have highlights or full colour, you’ll notice fresher colour and more shine after a few weeks.

You can use the Redken Acidic Bonding Concentrate Shampoo every wash, but we recommend alternating with a hydrating shampoo if your hair is fine or sensitive.

With daily use on fine hair, some may find their hair feels a bit drier. Washing two to three times a week? Use the Acidic Bonding Concentrate every time without issue. If you have a sensitive scalp or itchiness, start with once a week and see how your scalp responds.

The shampoo is sulphate-free; the conditioner contains silicones. These are two different things with distinct roles.

The sulphate-free shampoo cleanses without stripping natural oils, essential for damaged and coloured hair. Silicones in the conditioner make your hair feel smoother and easier to comb after washing. If you follow the curly girl method or want to avoid silicones, the conditioner isn’t the best choice. In that case, check out other products in the Damaged Hair category.

Many shampoos just cleanse without considering damaged hair’s needs. The Redken Acidic Bonding Concentrate line works differently: shampoo and conditioner share the same active base and boost each other’s effects. The shampoo opens the cleansing process at the right pH, the conditioner seals it. Using both gives a cumulative effect that single products can’t match.

Compared to sustainable bond-building lines like Olaplex, Redken Acidic Bonding Concentrate offers similar daily results for a friendlier price per wash. Those with bleached hair or highlights looking for a shampoo for damaged hair after bleaching that also works as a daily routine will find a practical solution here. Want to expand your routine? The Acidic Bonding Concentrate 24/7 Night & Day Serum works on hair repair all day long.
