A hair tie (also called a ponytail holder, hairkeeper, hair band, hair elastic, wrap around, gogo, or bobble) is a styling aid used to fasten hair, particularly long hair, away from areas such as the face. This is usually done as part of a hairstyle such as pigtails, bunches, or ponytails for straight, wavy, and loosely curled hair, and referred to as afro puffs, bunny tails, and "pineapples" for highly curled and highly textured natural hair. Two common types of hair tie are the scrunchie[1] and the elastic. The term can also include a fixed tie or rubber band which is placed through or around strands to hold specific parts of hair together, rather than tie it or clasp them together like a hair clip.
Hair ties' elasticity and durability vary according to the material or materials from which they are made.
