Redken Acidic Bonding Concentrate Shampoo — 10.1 fl oz, sulfate-free color-safe repair with citric acid and bonding complex

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

Designed as Redken’s most concentrated all-in-one strength-repair shampoo, this vegan formula cleanses gently while helping reinforce weakened internal bonds. The acidic pH helps balance the hair surface after chemical or thermal services, and the rich lather conditions strands to reduce roughness and support color longevity. It’s made for anyone who wants a salon-grade, science-backed approach to improving hair resilience without sulfates.

How does this shampoo help restore damaged hair?

Rather than only removing dirt and oil, the formula delivers a bonding care complex that targets weakened links inside the hair fiber. Regular use helps hair feel stronger and look more resilient by improving cohesion along the shaft.

• Citric acid assists in pH balancing to smooth cuticles and reduce friction.
• Bonding complex works to reinforce compromised inner bonds for visible strength gains.
• Vegan, sulfate-free base cleans without stripping essential moisture.

Will it protect my hair color and prevent fading?

The shampoo’s acidic formulation helps seal the hair surface, which can reduce color washout and maintain vibrancy between salon visits. It’s labeled color-safe and engineered to be gentle on treated strands while still providing effective cleansing.

• pH-balanced cleansing preserves color pigments under routine washing.
• Less aggressive surfactants mean gentler pigment retention than standard sulfates.
• Concentrated texture allows effective results with smaller doses, minimizing over-washing.

How should I use it for best results?

Apply a small amount to wet hair and massage evenly from roots to ends to create a wealthy lather; rinse and follow with a compatible conditioner or the matching Redken Acidic Bonding Concentrate conditioner for maximum repair. For severely compromised hair, alternate with regular nourishing treatments and avoid excessive heat styling while rebuilding strength.

• Use 2–3 times per week or as recommended by your stylist for maintenance.
• Pair with the Acidic Bonding Concentrate conditioner or mask to seal benefits.
• Conserve product: a little goes a long way due to its concentrated formula.

Is this shampoo safe for all hair types and chemical services?

The formula is crafted to be appropriate for a wide range of hair textures and damage types, including color-treated, chemically processed, heat-styled, and bleached hair. While it’s formulated to support and protect treated hair, consult your stylist if you have specific scalp conditions or extremely fragile hair.

• Sulfate-free and vegan, suitable for many hair concerns and routines.
• Acidic pH helps maintain post-service hair integrity for chemically treated strands.
• Recommended for ongoing maintenance of salon-treated hair to reduce breakage risk.

Who is this for: Redken Acidic Bonding Concentrate Shampoo is ideal for people with weakened, brittle, or chemically processed hair who want a professional-strength, sulfate-free cleanser that helps rebuild internal structure and supports color retention. It suits clients looking for concentrated, salon-grade repair in a routine-friendly shampoo that pairs with complementary conditioners and treatments from the Acidic Bonding Concentrate line.
