Abstract: The device of the present invention is a convertible ponytail holder/headband designed to remain secure during prolonged use and physical activities or when wet. The device includes a long strand of material and a bead with a through-bore. Both ends of the strand are threaded into the through-bore to form a closed loop. The positioning of the bead is adjustable, but remains secure once set due to friction and tension. For optimal friction and tension, the strand is formed of a seamless tubular material that while slightly elastic readily retains its shape. The diameter of the bead through-bore is approximately 0.6 times the width of the strand. In operation, the ponytail holder or headband is looped around a hair bundle or the wearer's head, respectively. To secure the device the bead is moved towards the loop and the loop is tightened.
