Redken Acidic Bonding Concentrate Shampoo for Damaged Hair, 33.8 fl oz — Sulfate-Free, Color-Safe

This ultra-rich vegan shampoo from Redken combines citric acid with the brand’s Bonding Care Complex to deliver strength repair, intense conditioning, and color-preserving cleansing in a single step. Formulated for all hair types and textures, the thick consistency means a little product covers a lot of strands, making it especially useful for hair that has been weakened by chemical services, heat styling, or environmental stressors.

How does this shampoo repair weakened and brittle hair?

The formula works at the fiber level to reinforce bonds that break during chemical processing and mechanical stress. Citric acid helps smooth the cuticle and balance surface pH while Redken’s Bonding Care Complex targets internal bonds to improve resilience and elasticity.

• Bonding Care Complex strengthens internal hair structure.
• Citric acid helps seal and smooth the cuticle for a sleeker finish.
• Thicker texture coats strands for concentrated action with smaller amounts.
• Vegan, sulfate-free base reduces harsh stripping of moisture and color.

Will it protect salon color and reduce fading?

Yes — the acidic formulation is designed to close and reinforce the hair surface, helping to lock in pigment and slow color fade between salon visits. Because it’s sulfate-free, it cleanses without aggressively lifting color molecules from treated strands.

• Acidic pH supports cuticle closure to retain color.
• Sulfate-free surfactants provide gentler cleansing on colored hair.
• Fragrance blends citrus and floral notes that don’t overwhelm salon scent profiles.

How should I use the Redken Acidic Bonding Concentrate Shampoo for best results?

A little goes a long way: start with a quarter-size amount and add more as needed depending on hair length and density. Massage gently into wet hair, focusing on the scalp and mid-lengths, then rinse; for best restoration, use as Step 1 of the Acidic Bonding Concentrate system with the matching conditioner and treatments.

• Begin with a small amount; the product is ultra-rich and concentrated.
• Work into a lather and rinse thoroughly; repeat if hair is heavily soiled.
• Pair with complementary Redken bonding products for maximum breakage reduction.

Can people with different hair types and damage levels use this shampoo?

The formula is suitable across textures—from fine to coarse—and addresses many damage sources including color processing, heat tools, and environmental wear. Its balancing approach provides conditioning and reinforcement without weighing hair down when used in appropriate amounts.

• Safe for all color-treated hair and various textures.
• Designed to tackle damage from chemicals, styling, sun, and friction.
• Concentrated consistency allows dose control for fine or thick hair.

Who is this for: Redken Acidic Bonding Concentrate Shampoo is ideal for anyone with fragile, chemically processed, or frequently styled hair who wants a salon-grade, sulfate-free cleanser that strengthens fibers and helps maintain color. Use it if you’re seeking a concentrated, professional-strength product to reduce breakage, smooth visible split ends, and improve manageability while preserving treated color.
