Uses
Headbands, or sweatbands, are worn around the forehead during physical activity to absorb sweat and keep it from reaching the eyes. Sweatbands are often made of a continuous loop of terrycloth, as it is a particularly absorbent fabric. Folded bandanas, usually knotted behind the head, also serve this purpose. Headbands are usually used for sports but have not been popular since the late 1970s or early 1980s.
