Abstract: A customizable wig can be reversibly altered to create a wide variety of hairstyles. A customizable wig comprises a single base shell having an outer surface, a plurality of fasteners affixed to its outer surface, and a plurality of hair segments that can be fastened to the shell. The hair segments comprise at least one crown segment, at least one mid-section segment, and at least one nape segment. The segments can be removably attached by a variety of fasteners such as hook and loop fasteners or snaps. In order to provide even more options for alternative hairstyles, the crown, mid-section, and nape segments can comprise more than one segment. Enhancements such as feathers, hair wefts, or beaded strings can be easily attached to create additional styles. A box is optimized for protection during storage and transport, as well as for display of the wig.
