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

Redken Acidic Bonding Concentrate Shampoo is a vegan, sulfate-free formula that cleanses and reinforces weakened hair bonds to reduce breakage and protect color.

Made for all types of damaged and color-treated hair, this professional-strength shampoo blends citric acid with Redken's bonding care complex to rebuild resilience from root to tip. The refill format delivers 25% more savings per milliliter and uses significantly less plastic per ml — a practical choice for regular use without sacrificing salon-grade performance. Its thicker texture means you need less product to achieve a full, conditioning lather that leaves hair easier to manage and more resistant to everyday stressors.

How does this shampoo strengthen damaged strands?

The formula targets weakened bonds inside the hair fiber using a specialized bonding complex and citric acid to help realign and reinforce cuticle layers. Regular use supports tensile strength and reduces the chance of breakage from styling and environmental wear.

• Bonding care complex helps reconnect and fortify internal hair structure.
• Citric acid creates an acidic environment that smooths cuticles for added resiliency.
• Thicker consistency coats strands, maximizing contact with active ingredients.

Will it protect my salon color while repairing damage?

This acidic shampoo is designed to be color-safe, helping minimize color fade while repairing mechanical and chemical damage. It cleanses without sulfates, which helps preserve vibrancy between salon visits when combined with professional color maintenance.

• Sulfate-free cleansing that is gentle on dyed hair.
• Acidic pH helps seal the cuticle to retain pigment and reduce fade.
• Formulated for frequent use on color-treated hair without stripping tone.

How should I use the refill bottle for best results?

Dispense a small amount into wet hair, lather, and focus on mid-lengths and ends where damage concentrates. Rinse thoroughly and follow with a compatible conditioner or treatment to lock in moisture and reinforcement.

• Use a coin-sized portion; the thick texture spreads easily across hair.
• Pair with Redken bonding conditioners or masks for deeper repair.
• Refill packaging reduces waste and stretches the cost-per-use.

How does the refill option benefit my routine and the environment?

The refill delivers more product per purchase and significantly reduces plastic use per milliliter compared with standard bottles, making upkeep of a salon-quality routine more economical and sustainable. The larger volume is ideal for households or frequent users who want consistent results without frequent repurchasing.

• 25% more savings per ml versus single-use formats.
• 68% less plastic per ml, lowering packaging waste over time.
• Convenient 16.9 fl. oz. refill minimizes trips to restock.
