The term 'certain hairpiece' can be summarized as a WIG, which is a three-letter word. Wigs are artificial head coverings made from human or synthetic hair, and they are often used to change a person's hairstyle or to cover up baldness. Wigs have been around for centuries, with the earliest known examples dating back to ancient Egypt. They are still popular today, and are used for a variety of reasons, including fashion, medical purposes, and theatrical performances.
