The system comprises: PA1 a) a plurality of first magnets adapted to be surgically implanted between the skin of the defined portion of the person's scalp and the person's skull, said first magnets being shaped like flat disks and coated with a hypoallergenic material; and PA1 b) a hairpiece adapted to cover the defined portion of the person's scalp, said hairpiece comprising: PA2 (i) a base fabric; PA2 (ii) a plurality of fibers secured to one side of the base fabric; and PA2 (iii) a plurality of second magnets, said second magnets being fastened to the other side of the base fabric. After the first magnets are implanted beneath the scalp, the hairpiece is secured to the scalp by magnetic attraction between the first and second magnets.
