Redken Acidic Bonding Concentrate Shampoo for Damaged, Color-Treated Hair — 1.7 fl oz, Sulfate-Free & Strengthening

Redken Acidic Bonding Concentrate Shampoo is a sulfate-free, vegan daily cleanser formulated to strengthen weakened bonds and reduce breakage in damaged, color-treated hair.

This concentrated shampoo pairs citric acid with Redken's bonding care complex to gently cleanse while targeting vulnerable areas of the hair shaft. It delivers extra conditioning and color fade protection in a thick, economical formula designed for all types of damage — from chemical processing to heat and environmental stressors. The result is smoother, more resilient strands without stripping salon color.

How does this shampoo rebuild strength in damaged hair?

The formula works by reinforcing hair's internal structure with a proprietary bonding complex supported by acidic pH from citric acid. That combination helps temporarily fortify weakened bonds along the hair fiber, improving elasticity and reducing the likelihood of breakage during styling.

• Bonding care complex targets weakened spots along the hair shaft
• Citric acid helps close the cuticle for smoother, stronger strands
• Sulfate-free surfactants gently cleanse without over-drying
• Thicker consistency coats hair, so less product is needed

Will it protect my salon color while repairing damage?

Yes — the acidic formulation is designed to help preserve color vibrancy by sealing the hair cuticle and minimizing color fade. Because it is free of harsh sulfates, it cleanses without aggressively stripping dye molecules, supporting longer-lasting color between salon visits.

• Acidic pH helps maintain cuticle alignment and color retention
• Color-safe, sulfate-free cleansing protects salon-treated hair
• Conditioning agents smooth the surface to reduce dulling
• Use with complementary Redken Acidic Bonding products for best results

How should I use this concentrated shampoo for best results?

Apply a small amount to wet hair, working into a lather from roots to ends, then rinse and follow with a matching conditioner or mask if desired. Because of its concentrated texture, a little goes a long way — especially on shorter hair or when hair is fragile.

• Wet hair thoroughly before applying a dime-sized to quarter-sized amount
• Massage gently to distribute; focus on mid-lengths and ends where damage is worst
• Rinse completely and pair with Redken Acidic Bonding Conditioner
• Use regularly for ongoing repair and color protection

Is this shampoo suitable for every hair type and damage source?

Redken designed this system for all hair types that have experienced mechanical, chemical, or environmental damage. Whether you color, heat-style, or have sun-exposed hair, the formula aims to restore manageability and reduce breakage without weighing hair down.

• Recommended for color-treated, chemically processed, or heat-damaged hair
• Works on fine to coarse textures; use less on finer hair to avoid buildup
• Vegan formula fits many lifestyle preferences
• Sulfate-free for gentler daily use

Who is this for: This shampoo is for anyone looking to rebuild and protect compromised hair fibers while preserving salon color — ideal for people with brittle ends, recent chemical services, frequent heat styling, or visible breakage. It suits clients and at-home users who want a professional-strength, concentrated repair cleanser that pairs well with a follow-up bonding conditioner or treatment.
