Wig

A wig is an artificial covering of hair worn on the head. In the Wizarding world, as in the Muggle world, wigs are used for a variety of reasons, including cosmetic enhancement, concealing baldness, as a fashion accessory, or for disguise. While many wigs in the magical world are ordinary, some are known to be enchanted. Their use ranges from simple vanity, as demonstrated by Gilderoy Lockhart, to being a component of formal, traditional attire, as suggested by portraits of historical wizards. It is likely that such items are sold in wizarding clothing shops like Gladrags Wizardwear, which is known for its unusual and eccentric apparel.

Though a minor element in the series, wigs are mentioned in several notable contexts:

• Gilderoy Lockhart's Wig: The vain Defence Against the Dark Arts professor wore a toupee to hide his baldness. After his Memory Charm backfired in the Chamber of Secrets, his resulting amnesia led him to pat his head in confusion and ask if his hair was a wig, confirming its existence.

• Formal and Historical Attire: During a visit to St. Mungo's Hospital for Magical Maladies and Injuries, Harry Potter saw a portrait of a sour-faced wizard wearing a long, silver wig. This style is reminiscent of formal wear from previous centuries, suggesting that wigs may have been, or still are, part of the traditional dress for members of esteemed bodies like the Wizengamot.

• In the film adaptation of Harry Potter and the Prisoner of Azkaban, the portrait of the Fat Lady is shown wearing a large, elaborate wig, a visual detail not mentioned in the novel (film).

• The Wizarding World website has confirmed the existence of enchanted wigs, specifically mentioning self-styling wigs as a magical fashion item (Pottermore).
