Abstract
Abstract Removably located within an elongated epithelium-lined tract (tunnel) surgically formed in the subcutaneous layer of the scalp is the elongated subdermal portion of a scalp anchor. Mounted on at least one end of the subdermal member is a flange or tab, closely overlying the subjacent surface of the scalp, the flange being attachable to an overlying hairpiece. A plurality of such anchors securely yet removably retains the hairpiece in the desired position on the scalp.
