Wearing a wig cap is optional and is a personal decision. It can be worn to secure any existing hair, or it can provide a barrier between your skin and the wig. It can also help protect your scalp if you have sensitive skin. There are several reasons why someone might choose to wear a wig cap: Securing existing hair: A wig cap can help keep any natural hair in place and prevent it from poking out from under the wig, creating a smoother and more seamless look. Barrier between skin and wig: Some people opt to wear a wig cap to create a barrier between their scalp and the wig, which can help with comfort and hygiene, especially if you tend to sweat or have sensitive skin. Scalp protection: For individuals with sensitive skin, wearing a wig cap can provide an extra layer of protection against potential irritation from the wig material.
