Shark FlexStyle Curl-Defining Diffuser in black. Enhances and defines natural curls while reducing frizz. Attaches easily to compatible Shark styling tools for even airflow and soft, voluminous results. The Shark FlexStyle® Curl-Defining Diffuser attaches to the Shark FlexStyle® for fast, even drying from root to tip. To enable curl-perfection, our diffuser features retractable and extendable prongs. Retract prongs for shorter, finer hair and less heat on the scalp. Extend prongs for longer, thicker hair and for reaching and lifting at the root. New. No box. Came in a kit and I do not need this for my hair type.
