A hair band comprises a stretchable body and a center hole. The center hole increases in diameter when the hair band is moved from a rest position to a stretched position. A distance between an outer edge of the body and an outer edge of the center hole is greater than the center hole diameter when the hair band is in a rest position. The distance between the outer edge of the center hole and the outer edge of the body decreases and the inner diameter increases as the hair band is stretched. In some embodiments, the body is hollow and filled with one or more of a gel substance, a granular solid, and a viscous liquid. In some embodiments, the hair band is manufactured by one or more of an extrusion molding process and an injection molding process. |
