A ponytail is a hairstyle in which most or all of the hair on the head is pulled away from the face, gathered and secured at the back of the head with a hair tie, clip or similar device, and allowed to hang freely from that point. It gets its name from its resemblance to the undocked tail of a horse or pony. Ponytails are most commonly gathered at the middle of the back of the head, or the base of the neck.
