<p>This invention relates to a wig having a shape retaining member for preventing curving-up and distortion of a wig base. This shape retaining member (12) is made of a shape memory alloy having a transformation temperature (Af point) higher than the temperature of an ambient between the surface of the head of the user of the wig and the wig base when the wig (10) is fitted to the head, and is disposed at a predetermined position on the inner or outer surface of the wig base (11). When the shape retaining member gets corrugated in the course of use, it is heated to a temperature higher than the transformation temperature so that it regains the shape that is stored in advance. Therefore, the wig can be repeatedly fitted as if it were a new one.</p> |
