Why did people wear wigs back in the day?

People wore wigs in the past for various reasons, including to signify social status, conceal baldness, and adhere to fashion trends. In the 17th and 18th centuries, particularly in Europe, elaborate wigs became symbols of wealth and power among the aristocracy. Additionally, wigs offered a practical solution for hygiene and convenience, as they could be removed and cleaned easily. The trend eventually declined as societal norms and styles changed.
