Redken Acidic Bonding Curls Sulfate-Free Shampoo — For Curly & Coily Hair, Hydrating Repair with Avocado Oil

Redken Acidic Bonding Curls Sulfate-Free Shampoo is a silicone-free, bond-building cleanser that gently removes buildup while strengthening and defining curly and coily hair.

This shampoo was created for curls and coils that need both cleansing and structural repair. Its lightweight formula uses an acidic bonding system to support curl pattern integrity, while natural oils and humectants help hydrate without weighing strands down. Designed to pair with the matching conditioner and leave-in treatment, it targets frizz, detangling, and elasticity for curl types from 3A to 4C.

How does this shampoo help damaged or chemically processed curls?

The formula focuses on rebuilding inner bond integrity with targeted ingredients that work at the fiber level. It gently lifts dirt and product residue without aggressive sulfates, so curls retain moisture and shape. Regular use in the Acidic Bonding Curls system improves manageability and reduces the appearance of split ends.

• Curl-Bond Technology: citric acid, glycine, and urea to support internal bond strength.
• Sulfate-free cleansing that removes buildup while protecting natural oils.
• Nutrition from avocado oil and shea butter to restore softness and reduce breakage.

Will this shampoo define my curl pattern and reduce frizz?

Yes — the product aims to reinforce curl shape and smooth the cuticle so coils sit more uniformly. When used as a regimen, it helps control frizz for multiple days and improves curl clumping for clearer definition. The silicone-free blend gives body and movement instead of a coated, weighed-down finish.

• System results show reduced frizz and enhanced curl definition for up to four days.
• Lightweight conditioning keeps volume and avoids limp curls.
• Helps detangle strands so curls clump with better form after styling.

How should I use it in my curl routine for best results?

Apply to wet hair, massage into the scalp and through lengths to dissolve grime, then rinse thoroughly. Follow with the Acidic Bonding Curls Conditioner to lock in hydration and complete the bonding repair. For intensive care, add the leave-in treatment to wet or damp hair before styling to preserve elasticity and definition.

• Use with matching conditioner and leave-in for the full bonding system benefits.
• Suitable for color-treated curls; use as your regular cleansing step or as needed.
• Works well with gentle detangling tools to minimize mechanical stress.

Which ingredients hydrate without weighing curls down?

The shampoo balances lightweight oils and moisturizers to soften strands while maintaining spring and bounce. Avocado oil and shea butter provide emollient nourishment, while vitamin B5 and coconut-derived agents support moisture retention. The acidic actives support bond repair rather than superficial coating.

• Avocado oil and shea butter for targeted hydration and improved elasticity.
• Vitamin B5 (panthenol) for moisture retention and smoother texture.
• Coconut-derived cleansing agents that avoid harsh stripping.
