Wig

A wig is a head covering made from human hair, animal hair, or synthetic fiber that is worn for fashion or other reasons, including cultural tradition and religious observance. The word wig is short for periwig and first appeared in the English language around 1675.

Some people wear wigs to disguise baldness; a wig may be used as a less intrusive and less expensive alternative to medical therapies for restoring hair. Wigs may also be used as an article of apparel, or to fulfill a religious obligation. Actors often wear costume wigs in order to portray characters.
