Abstract: A one-piece flexible hair curler assembly used for day and night use comprising a collapsible body, elongated extensions at right angles on its distal ends with attached protuberances that hold the assembly securely in place. The flexi hair curler assembly is fabricated of lightweight, moisture and heat resistant, flexible material including silicone. To use, the appendages are flexed away from the curler body as the hair is wound around the core. After reaching the desired position, the appendages are released, and the protuberances hold the apparatus in place without the aid of additional hair fasteners or clips. The curler molds to the wearer's head and scalp for maximum comfort while remaining secure to facilitate the setting of curls in the hair. Unlike other hair curlers or rollers, the flexible curler system is comfortable, secure and cost effective.
