Redken Bonding Concentrate Shampoo Refill 16.9 fl oz – Acidic, Sulfate-Free Repair for Damaged & Color-Treated Hair

Redken Acidic Bonding Concentrate Shampoo (refill) is a vegan, sulfate-free professional cleanser that reinforces weakened hair bonds to strengthen and reduce breakage for all types of damaged, color-treated hair.

This concentrated formula uses citric acid plus Redken's Bonding Care Complex to rebuild hair resilience while protecting salon color. Packaged as a 16.9 fl. oz. refill, it delivers the same salon-grade repair benefits with 25% more savings per milliliter and 68% less plastic per milliliter versus the standard bottle. Ideal for daily or weekly use depending on styling and damage level, the shampoo cleanses, conditions and supports overall hair health without harsh sulfates.

How does this shampoo repair weakened hair bonds?

The formula targets compromised areas along the hair fiber with citric acid to balance surface pH and a bonding complex designed to reconnect and reinforce internal structure. Regular use helps reduce the appearance of frizz and split ends by supporting the strand from the inside out. It’s concentrated, so a little goes a long way, coating fibers for immediate smoothing and long-term resilience.

• Citric acid to restore hair surface pH and improve cuticle lay.
• Bonding Care Complex to strengthen internal hair structure.
• Thicker texture that spreads efficiently—less product required.
• Reduces breakage from styling and environmental stressors.

Will this protect my color-treated hair from fading?

Yes — the acidic formulation helps seal the cuticle, which limits color molecules from washing away and preserves vibrancy between salon visits. The sulfate-free base cleans without stripping pigments, so dyed hair maintains tone longer while getting repair benefits. Use with complementary Redken color-care products for best results.

• Acidic pH helps flatten the cuticle to lock in color.
• Sulfate-free surfactants prevent aggressive pigment removal.
• Formulated for safe use on color-treated and highlighted hair.
• Supports salon color longevity with regular use.

How should I use the refill to get optimal results?

Dispense a small amount into your palm, emulsify with water, and massage into scalp and lengths twice if hair is heavily soiled or highly damaged. Rinse thoroughly and follow with a Redken conditioner or mask for added moisture and smoothing. Because the shampoo is concentrated, begin with less product than you would a standard shampoo and increase only if needed.

• Use sparingly—concentrated texture covers more hair per pump.
• Apply to wet hair, massage, and rinse; repeat if necessary.
• Pair with a Redken conditioner or treatment for best hydration.
• Safe for daily use on most hair types; adjust frequency by damage level.

What makes the refill better for the planet and your wallet?
