Redken Acidic Bonding Curls Sulfate-Free Shampoo — For Curly Hair (12.5 oz) | Curl-Bond Repair & Hydration

This salon-grade shampoo is formulated to address the specific needs of curly and coily hair that has been weakened by styling, chemical services, or environmental stress. Redken combines a lightweight, hydrating base with Curl-Bond Technology—citric acid, glycine and urea—plus nourishing oils to help restore elasticity, reduce frizz and leave curls visibly healthier without silicones that can weigh hair down.

How does this shampoo rebuild weakened curl structure?

The formula uses Curl-Bond Technology to support internal fiber repair: citric acid helps refine the cuticle, glycine and urea assist bond-building and resilience, so curls feel stronger and more cohesive after washing. Results are amplified when the shampoo is paired with the matching conditioner and leave-in treatment.

• Citric acid helps smooth and seal the hair surface for improved shine.
• Glycine and urea work within the hair to support bond integrity and elasticity.
• System use (shampoo, conditioner, leave-in) delivers maximum repair and definition.

Will this product keep my curls hydrated without weighing them down?

Yes—this shampoo is silicone-free and formulated with lightweight yet nourishing ingredients like avocado oil, shea butter and coconut oil to hydrate curls while maintaining volume. The blend balances moisture and lift so waves and coils stay defined for days.

• Avocado and coconut oils provide penetrating moisture without heavy residue.
• Shea butter locks in softness and improves manageability.
• Sulfate-free surfactants cleanse gently to prevent over-drying.

How does it help with frizz and detangling?

In consumer testing, the Acidic Bonding Curls system reduced frizz and made hair easier to detangle. The shampoo detaches product buildup and smooths the strand surface so combing and styling are less stressful on the curl pattern.

• Gentle cleansing removes residue that causes stiffness and frizz.
• Improved surface condition reduces friction for easier detangling.
• System use provides up to 96 hours of improved frizz control and hydration.

Is this safe for color-treated or chemically processed curls?

The silicone-free, vegan-style formula is suitable for color-treated hair and for curls that have undergone chemical services. Its gentle surfactants and restorative actives are designed to protect color while addressing damage and restoring curl definition.

• Color-safe, sulfate-free cleansing minimizes fade and striping.
• Bond-supporting ingredients target structural weakness from processing.
• Lightweight oils deliver moisture without sealing in buildup.

Who is this for: Redken Acidic Bonding Curls Shampoo is built for people with curly and coily hair types—especially patterns from 3A to 4C—who want to rebuild curl strength, reduce frizz, and keep bounce without silicones. It’s a good match for anyone recovering from over-processing or seeking a hydrating, salon-quality wash that works best when used with the Acidic Bonding Curls conditioner and leave-in treatment.
