In Britain, the fashion of wearing wigs began in 12 century. At that time, wearing fake headgear was not just the patent of judges and lawyers. People in the upper class regard wearing wigs as a fashion and a formal dress for formal occasions or salons. In France, since King Louis XIII, wearing a fake headdress is a symbol of social status. Many industries also take wearing fake headgear as a sign.
However, the French Revolution and the American War of Independence swept away all signs of status and rank. So now only the court systems in Britain and a few countries keep this habit. Judges in Britain and judges in former Commonwealth countries and regions, including Hong Kong, will wear a shawl wig on their heads, lawyers will wear small wigs, and judges and lawyers will wear black robes.
When judges put on black robes and fake laws, they can hide their true colors and get rid of selfish distractions, and they can truly become the embodiment of the rule of law. The wig used by the judge is different from the ordinary wig. In England, the wig used by judges has three curls on each side, while the royal family has only two. But in Scotland, contrary to England, the royal family uses three curly wigs, while the judge only uses two curly wigs.
Extended data:
The judge would rather put up with lice than change wigs frequently. The reason is based on a saying that the longer you wear a wig, the dirtier it is and the darker it is, indicating that you have been engaged in the legal profession for a long time. In the judicial field, seniority and age are crucial. In a sense, the more fake headgear a judge wears, the more experience a judge has in trial.
Especially in Britain, there is a debate about whether to abolish wigs. According to a survey approved by the Supreme Court Justice, two thirds of people think that this kind of wig should be abolished except in criminal cases. Judges and lawyers who wear wig have complained that wearing wig is hot, smelly and uncomfortable.
