Deep Wave: Features a tight, consistent, and well-defined "S" pattern. The curls are much tighter and closer together than a body wave, which gives the wig a lot more volume and a fuller, more "curly" appearance. Deep wave hair holds its curl pattern exceptionally well.
Body Wave: Has a looser, more relaxed "S" wave pattern. It creates a soft, natural, and more subtle wavy look. Body wave is generally considered lower-maintenance and more versatile for styling, as it can be straightened more easily than deep wave hair.
