Cranial hair prostheses are different than department store wigs in quality, performance and service. Prostheses are made with specialized material sensitive to the needs of the individual. They come in a variety of styles and colors. The fit is adjustable to each person's size and is also custom cut and styled. A department store wig has a set style what you see is what you get. Often, they don't fit correctly and have a heavy, fuller/wiggy appearance.
