head covering mimicking hair

A wig is an artificial covering of hair. The word is short for periwig and appeared in the English language around 1675. Some people wear wigs to hide the fact that they are bald, which means they have very little or no scalp hair. Actors often wear wigs to disguise their appearance or get into character. In Britain and other Commonwealth nations, some public employees, such as judges and barristers, wear wigs.

Many composers during the 18th century wore wigs.
