 hairpiece

What is claimed is:

1. A hairpiece attachment device for attaching a hairpiece to a central scalp bald area of a user’s head, said device comprising:
          a first component attachable to said central scalp bald area, said first component having an inner edge and a first plurality of hinge-type hollow cylindrical segments spaced along said inner edge;
          a second component on which a hairpiece is attachable, said second component having an outer edge and a second plurality of hinge-type hollow cylindrical segments spaced along said outer edge;
          said first and second pluralities of hinge-type segments aligned to interfit with one another to form a continuous passageway through said segments;
          two flexible pins, each said pin insertable through an opposite end of the passageway of said hinge-type segments, thereby attaching said first component to said second component such that insertion and withdrawal of said pins from said passageway renders the hairpiece removably attachable to the head as a cover for said central scalp bald area.
