The artificial hair covering that completely conceals the client's hair is known as a?

A wig is defined as an artificial hair covering that is designed to completely conceal the wearer’s natural hair. Wigs are made from either synthetic fibers or human hair and can vary in style, length, and color, allowing users to change their appearance significantly. They serve various purposes ranging from fashion to medical needs, such as for individuals experiencing hair loss due to health issues.

In contrast, a hairpiece generally refers to a smaller section of hair that may complement or enhance the existing hair rather than cover it completely. Wigless, as a term, is not widely recognized as a specific type of hair covering and typically indicates a style where no wig is used. A switch is a type of hair attachment that is usually added for length or volume but does not serve to cover the entire head of hair. Thus, the concept of a wig uniquely fulfills the requirement of completely concealing a client's natural hair.
