Redken Acidic Bonding Concentrate Shampoo 33.8 fl oz — Sulfate-Free Repair for Damaged Hair

Redken Acidic Bonding Concentrate Shampoo is Step 1 in Redken's concentrated repair system, formulated to support weakened hair fibers and protect color. Infused with citric acid and Redken's Bonding Care Complex, this thick, vegan formula coats strands to help reduce breakage and improve manageability while preserving salon color. Its citrus-floral scent balances freshness and warmth, and a little goes a long way—start with a small amount and add more to suit hair length and texture.

How does this shampoo help hair that feels weak or brittle?

The shampoo works by reinforcing internal bonds within the hair fiber and delivering conditioning agents that smooth and strengthen the strand. Regular use helps improve tensile strength and reduces the visible effects of mechanical and chemical stress.

• Bonding Care Complex targets and supports fractured bonds along the hair shaft.
• Citric acid restores acidic pH balance to smooth cuticles and boost shine.
• Thicker consistency means fuller coverage with less product per wash.

Will it protect my color-treated hair and prevent fading?

This acidic formula is designed to protect salon color by sealing the cuticle and reducing color loss during washing. The sulfate-free base provides a gentler cleanse that removes impurities without stripping pigments, helping hues stay truer between salon visits.

• Sulfate-free surfactants cleanse without harsh pigment removal.
• Acidic pH helps close the cuticle to lock in color molecules.
• Conditioning agents decrease friction and fading from styling and sun exposure.

How should I use the shampoo for best results?

Because the formula is concentrated and ultra-rich, begin with a small, quarter-sized amount and add more as needed based on hair thickness and length. Massage into wet hair, work into a lather focusing on roots and damage-prone areas, then rinse thoroughly and follow with the matching conditioner or treatment for the full system benefits.

• Start conservative—less product covers more due to the thick texture.
• Use as Step 1 in the Acidic Bonding Concentrate regimen for optimal repair.
• Pair with conditioner or intensive treatments to reduce breakage and split ends.

What types of damage and hair textures does it suit?

The shampoo is formulated for all types of damaged or processed hair, including chemically treated, heat-styled, sun-exposed, and mechanically stressed strands. It works across textures—fine to coily—offering strengthening and smoothing without weighing hair down when used as directed.

• Safe for color-treated hair and various textures.
• Helps repair damage from dyeing, bleaching, heat tools, and environmental exposure.
• Vegan formulation free from sulfates supports gentler daily or weekly use.

Who is this for: Redken Acidic Bonding Concentrate Shampoo is intended for anyone seeking a concentrated, salon-grade solution to strengthen and repair damaged hair while maintaining color. It's a practical choice for clients who regularly color or chemically treat hair, those who use heat tools frequently, and anyone noticing increased breakage, split ends, or rough texture. Use it as part of a full bonding routine for the greatest reduction in breakage and smoother-looking hair.
