After the fall of the Roman Empire, the use of wigs fell into abeyance in the West for a thousand years until revived in the 16th century as a means of compensating for hair loss or improving one's personal appearance. They also served a practical purpose: the unhygienic conditions of the time meant that hair attracted head lice, a problem that could be much reduced if natural hair were shaved and replaced with a more easily de-loused artificial hairpiece. Fur hoods were also used in a similar preventative fashion.

In Britain and most Commonwealth nations, special wigs are also worn by barristers, judges, and certain parliamentary and municipal or civic officials as a symbol of the office. The original purpose of the legal wig was said to provide a form of anonymity and safety (i.e. disguise). Today, Hong Kong barristers and judges continue to wear wigs as part of court dress as an influence from their former jurisdiction of the Commonwealth of Nations.
