Redken Acidic Bonding Curls Sulfate-Free Shampoo for Curly Hair — Avocado & Shea, Bond-Building Care

Redken Acidic Bonding Curls Sulfate-Free Shampoo gently cleanses curly and coily hair while rebuilding internal bonds to improve curl strength and definition.

This shampoo is designed specifically for wavy to coily patterns (3A–4C) that need gentle cleansing plus restorative care. The silicone- and sulfate-free formula pairs citric acid, glycine and urea (Curl-Bond Technology) with nourishing oils to remove buildup without stripping moisture, leaving curls more defined, elastic and easier to detangle when used as part of the Acidic Bonding Curls system.

How does this shampoo repair damaged curls?

The product uses a bond-building blend that targets internal hair structure while cleansing. Instead of heavy silicones, it relies on acidic actives and amino components to help reinforce weakened links inside the strand and improve curl resilience over repeated use.

• Curl-Bond Technology: citric acid, glycine and urea to support bond integrity
• Lightweight cleansing removes buildup without over-drying
• Nourishing oils help restore elasticity and softness

Will this shampoo weigh down my curls or affect color-treated hair?

No — the formula is silicone-free and made to be lightweight, so curls keep volume and bounce. It is also suitable for color-treated hair, helping maintain vibrancy while delivering hydration and conditioning benefits.

• Silicone-free texture maintains natural curl pattern and lift
• Vegan-friendly, gentle enough for color-treated strands
• Sulfate-free surfactants cleanse without harsh stripping

How does it help with frizz, detangling and hydration?

Combined with the matching conditioner and leave-in, the system reduces frizz and eases comb-through thanks to nourishing butters and oils. The formula delivers multi-day hydration and smoother cuticle feel to make styling simpler and to preserve curl definition.

• Avocado oil and shea butter provide lasting moisture and slip
• Improved detangling and reduced breakage during styling
• System use reported to reduce frizz and extend defined hold up to several days

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

Wet hair thoroughly, apply a quarter-to-dime-sized amount depending on length and density, lather gently focusing on the scalp, then rinse. For optimal repair and definition, follow with Acidic Bonding Curls Conditioner and the Leave-In Treatment as part of a regular regimen.

• Concentrate shampoo on the scalp and roots; rinse through lengths
• Pair with conditioner and leave-in for full bond-building benefits
• Use consistently to support improved curl shape and manageability
