STOP wearing stocking caps under your wigs ASAP. Why wear something on your head daily that is drying your hair out when you can wear something that protects it. The Wig Grip x Slay Avenew prevents headaches by eliminating wig related tensions and places a barrier between your scalp and the wig's interior cap lining by offering a snug and secure fit. The wig cap is composed of highly absorbent bamboo cotton blends that absorbs moisture and keeps the scalp cool.
