Redken Acidic Bonding Concentrate Shampoo, 10.1 fl oz – Sulfate-Free, Color-Protecting Repair

Redken Acidic Bonding Concentrate Shampoo is a vegan, sulfate-free shampoo formulated to reinforce weakened hair bonds, reduce breakage, and protect color while providing rich conditioning.

This concentrated salon-grade shampoo uses a bonding care complex and citric acid to balance pH and help restore strength to hair that’s been weakened by coloring, heat styling, or chemical services. The formula produces a luxurious lather that cleanses without stripping, delivering conditioning and color fade protection in a single step. It’s designed for all hair types and levels of damage, from mild surface wear to chemically processed strands.

How does this shampoo rebuild strength in damaged hair?

The shampoo contains a concentrated bonding complex that targets weakened areas of the hair fiber and helps reinforce internal bonds, while citric acid helps maintain an acidic pH to smooth and seal the cuticle. Together, these ingredients reduce visible signs of breakage and improve hair resilience after repeated use. Results are cumulative: continued use supports stronger-feeling strands and improved manageability.

• Bonding care complex helps reconnect and fortify compromised hair structure.
• Citric acid balances pH for sealed cuticles and smoother hair surface.
• Rich formula conditions as it cleanses to minimize mechanical damage during washing.

Will it preserve salon color and reduce fading?

The acidic pH and gentle, sulfate-free base are formulated to protect color molecules from premature fading. By avoiding harsh detergents and keeping the hair cuticle more closed, the shampoo helps lock in color vibrancy. For best results, use as part of a color-care routine and follow with conditioning or treatment products recommended for color-treated hair.

• Sulfate-free cleansing reduces stripping of color pigments.
• Acidic formulation helps maintain cuticle integrity to retain color longer.
• Works well alongside Redken color-care treatments and conditioners.

How should I use it for the best results?

Wet hair thoroughly, apply a small amount, and gently massage into the scalp and lengths until a rich lather forms, then rinse. For damaged or chemically treated hair, follow with a compatible Redken conditioner or bonding treatment to lock in benefits. Frequency depends on hair type and styling habits—use regularly in place of your usual shampoo for ongoing repair and protection.

• Use a small amount — concentrated formula foams richly to cover hair with less product.
• Pair with Redken Acidic Bonding Concentrate conditioner or treatment for deeper repair.
• Suitable for daily or alternate-day use depending on oiliness and styling needs.

Is this shampoo safe for all hair types and routines?

Yes — the formula is engineered for a wide range of hair textures and levels of damage, including color-treated, chemically processed, and heat-styled hair. It is vegan and free of sulfates, making it gentler on delicate, porous, or chemically altered strands. While not a medical treatment, it’s a preventive and reparative daily-care product suited for salon and at-home use.

• Vegan and sulfate-free for gentler daily cleansing.
• Effective on fine to coarse hair and on bleached or colored hair.
• Designed to integrate into professional and consumer haircare routines.

Who is this for: Redken Acidic Bonding Concentrate Shampoo is aimed at anyone with damaged, processed, or color-treated hair who wants a concentrated, salon-quality cleanse that both conditions and helps rebuild strength. Choose this if you frequently color or heat-style your hair, notice breakage or fragility, or want a pH-balanced, sulfate-free shampoo to preserve color and improve manageability.
