Abstract
Abstract A base member, which may be a thin, flexible formed plastic sheet, is provided with a plurality of needles to each of which is attached a tuft of hair. In a surgical procedure, a section of a patient''s scalp is lifted. The base is inserted on the scalp and the section of lifted scalp is replaced to cover the base. In replacing the section of scalp, the plurality of needles pierce the scalp section and project therefrom. Each needle may then be withdrawn from the base and scalp, pulling its tuft of hair through the needle hole. Each tuft of hair is knotted or otherwise sewn at its inner end so as to be secured from pulling entirely out of the plastic base and the scalp. When each tuft has been pulled to the full extent of its permitted travel, the needle is snipped off leaving an area of hair secured within the scalp.
