A closure wig is a type of wig that includes a closure, which is a piece of lace with hair hand-tied to it. It is used to close off a wig or a particular style, giving the illusion that the natural hair is growing from the scalp. Closures typically come in 4x4 inches in size and are available in different styles, including three-part, free part, and middle part. They are less expensive than frontals and offer fewer styling options, but they are versatile and easy to maintain. Unlike frontals, closures are limited to three styles and cannot be pulled back into a ponytail
