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

Redken Acidic Bonding Concentrate Shampoo is a concentrated, sulfate-free cleansing formula that restores weakened hair bonds, strengthens brittle strands, and preserves color in damaged or processed hair.

This concentrated 1.7 fl oz shampoo combines citric acid with Redken’s bonding care complex to target breakage and improve hair resilience without stripping color. Designed for daily use on all types of damaged hair, the vegan formula lathers into a thick, conditioning wash that coats fibers for visible smoothing and protection after chemical services, heat styling, sun exposure, or mechanical stress.

How does this shampoo rebuild weakened hair bonds?

The formula uses a bonding care complex that works at the fiber level to reinforce connections along the hair shaft, reducing the chance of breakage. Citric acid helps restore the hair’s natural pH and smooth the cuticle so treatments and styling actives perform better.

• Bonding complex repairs internal hair structure to resist snapping.
• Citric acid balances pH, sealing the cuticle for smoothness.
• Concentrated texture means less product needed to coat each strand.

Will it protect my color-treated hair from fading?

Yes — the acidic pH and sulfate-free surfactants gently cleanse without stripping pigment, helping color last longer between salon visits. The conditioning action also reduces surface roughness that can make color appear dull.

• Sulfate-free cleansing preserves salon-applied dyes.
• Acidic formula maintains cuticle closure to lock in color.
• Conditioning agents add shine, preventing color from looking flat.

How do I use this concentrated shampoo for best results?

Apply a small amount to wet hair, emulsify to a rich lather, then rinse and repeat if needed; follow with your preferred conditioner or the matching Redken Acidic Bonding Concentrate conditioner or mask for deeper repair. Because it’s concentrated, a little goes a long way—especially on short or fine hair.

• Use sparingly: a coin-sized amount for most hair lengths.
• Massage thoroughly to lift impurities and allow bonding agents to work.
• Pair with other acidic-bonding products for a complete regimen.

Is this shampoo suitable for my hair type and styling routine?

Formulated for all types of damaged or processed hair, it’s effective on chemically treated, heat-stressed, sun-exposed, or mechanically fragile strands. It’s color safe and vegan, making it appropriate for those seeking professional-strength repair without sulfates or animal-derived ingredients.

• Safe for color-treated and highlighted hair.
• Works on fine, medium, and coarse textures when damaged.
• Supports hair routinely exposed to heat styling or chemical services.

Who is this for: Redken Acidic Bonding Concentrate Shampoo is aimed at anyone with weakened, brittle, or chemically processed hair who wants a professional-strength, sulfate-free cleanser that repairs bonds and protects color. Ideal for salon clients, frequent stylers, and anyone seeking a concentrated, vegan hair-repair shampoo that delivers conditioning, resilience, and smoother-looking strands.
