What is a wig?

A wig is defined as an artificial hair covering that is made from interwoven hair, either synthetic or human, designed to be worn on the head for various purposes, including fashion, convenience, or to cover hair loss. The purpose of a wig is to mimic the look of natural hair, allowing individuals to change their appearance easily or to provide a solution for those experiencing hair thinning or loss.

The term "artificial hair covering" clearly aligns with the definition of a wig, as this is a key characteristic that distinguishes it from other hair-related items. The construction of the wig, using interwoven strands of hair, is also crucial because it contributes to the overall natural appearance and feel, making it versatile for varying styles and occasions.

In contrast, the other options describe unrelated concepts. A wig is not made from metal, nor does it serve as a type of hair extension, nor is it categorized primarily as a treatment for hair loss, although it can be used for that purpose. The focus on interwoven hair sets the correct description apart, confirming the understanding of what constitutes a wig in the realm of hair care and fashion.
