Curl Retention

The Curl Retention test evaluates the efficacy of hair care products in preserving and enhancing natural or styled curls. This assessment involves applying the product to curled hair and assessing the product's ability to maintain the shape, definition, and longevity of curls. The test examines factors such as curl retention, bounce, and resistance to humidity-induced frizz. By analyzing the performance of hair care products on curl retention, this test assists in the development of products that promote long-lasting, well-defined curls with improved manageability and frizz control
