A hair tie, also known by the names listed below, is an item 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, ponytail 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 ties are the scrunchie and the hairpin.
Hair ties' elasticity and durability varies according to the material or materials from which they are made. Most use elastic, rubber or stretchy forms of cotton, and are usually used to make a pony tail.
