Redken Acidic Bonding Curls Shampoo – Silicone-Free, Sulfate-Free for Damaged Curls | Curl Definition

Silicone-free care for curly hair that deserves definition

Redken's Acidic Bonding Curls Shampoo is a lightweight, silicone-free cleanser designed for curly and coily hair, including damaged or chemically processed curls. It cleanses without weighing curls down, helping to preserve the natural curl pattern while adding essential moisture. The formula is part of Redken’s first silicone-free bonding care regimen, working in harmony with the conditioner and leave-in treatment in the same line.

Powered by Curl-Bond Technology, this shampoo blends Citric Acid, Urea, and Glycine to help strengthen curls from the inside out. Expect improved elasticity, smoother detangling, and more natural body, with hydration that lasts across multiple days. The formula also contains avocado oil and shea butter to nourish strands and support moisture balance, making it suitable for color-treated hair as well.

In consumer testing, the system showed notable results when used together: 92% reported healthier and more defined curls after a single use, curls looked less damaged, and split ends appeared reduced. In addition, 91% found detangling easier, and frizz was reduced by up to 85% for up to 96 hours when paired with the full Acidic Bonding Curls routine. While individual results vary, many users notice a lighter feel, smoother texture, and more manageable curls after washing.
