Redken Acidic Bonding Concentrate Shampoo for Damaged Hair – 10.1 fl oz, Sulfate-Free & Color-Safe

Redken Acidic Bonding Concentrate Shampoo is a concentrated, sulfate-free shampoo formulated with citric acid and a bonding care complex to strengthen and repair weakened, damaged, or color-treated hair.

This professional-strength shampoo delivers a rich, conditioning lather that targets weakened bonds within the hair fiber while helping preserve salon color. Designed with an acidic pH, the formula helps rebalance hair surface after chemical services and thermal styling. Vegan and sulfate-free, it’s intended as an everyday-strengthening cleanse for hair that has become brittle, porous, or fragile from color, bleach, or heat.

How does this shampoo rebuild hair strength?

The Acidic Bonding Concentrate Shampoo uses a concentrated bonding care complex to reinforce weakened connections inside the hair strand. By acting at the bond level and providing gentle cleansing, it helps hair feel firmer and less prone to breakage over repeated use.

• Contains a bonding care complex to support internal hair structure
• Citric acid helps balance pH and smooth cuticle layers
• Sulfate-free surfactants clean without stripping natural moisture

Will it help protect my color between salon visits?

Yes — the acidic pH and conditioning agents work together to reduce color fade by keeping the hair surface sealed and less porous. The formula is labeled color-safe and formulated to minimize the mechanical and chemical stresses that accelerate color loss.

• Acidic formulation helps maintain cuticle alignment for less pigment loss
• Rich lather cleans while limiting harsh stripping agents
• Suitable for use on color-treated and highlighted hair

How should I use it for best results?

Use on wet hair, massage into a lather focusing on roots and areas of damage, then rinse thoroughly. For deeper repair, follow with the matching Acidic Bonding Concentrate conditioner or treatment from Redken to complete the bonding system.

• Apply a small amount; concentrated formula lathers well so less product is needed
• Pair with conditioner or leave-in treatments from the same line for targeted repair
• Use regularly after chemical services or frequent heat styling for maintenance

Is this gentle enough for daily use and all hair types?

Formulated without sulfates and with a pH that supports hair surface integrity, this shampoo is gentle enough for many users to use regularly. It’s created to address multiple kinds of damage, including processing, thermal stress, and mechanical breakage.

• Vegan, sulfate-free formula suited to various hair textures
• Designed for damaged, processed, bleached, or heat-stressed hair
• Recommended for anyone seeking to reduce breakage and refresh salon-treated hair

Who is this for: This shampoo is best for people with weakened, brittle, or chemically treated hair who want a professional, concentrated option to strengthen strands, protect color, and improve manageability. Ideal for clients who regularly color, bleach, or heat-style their hair and want a sulfate-free, pH-balanced cleanser to support long-term hair resilience.
