A hair extension for covering a bald region of a head of a user includes a wig having a hair portion, a resilient head band fixedly attached to the hair portion, and a fastener removably attached to the hair portion and adjustably mated to the head band. Notably, a portion of the head band as well as an entirety of the fastener each is seated beneath the hair portion and thereby not visible from an external line of sight directed to the hair portion.
