A wig grip, also known as a wig band or wig liner, is a type of headwear worn under a wig to keep it securely in place. Wig grips are typically made of thin, stretchy material, such as nylon or spandex, and are designed to fit snugly around the head. They can be worn with any type of wig, but are especially helpful for people with fine hair or oily scalps.
Wig grips serve several important functions. First, they help to prevent the wig from slipping or shifting out of place, even during vigorous activity. Second, they can help to absorb sweat and oil from the scalp, which can help to keep the wig looking fresh and clean. Third, wig grips can help to protect the scalp from irritation and chafing.
