What are headbands made of?
A headband is a clothing accessory worn in the hair or around the forehead, usually to hold hair away from the face or eyes. Headbands generally consist of a loop of elastic material or a horseshoe-shaped piece of flexible plastic or metal.
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. They also come in the form of wristbands.
