Is the permissibility of wearing a wig among the Hanafis and Malikis restricted solely to pure, non-human hair? And is it permissible for Malikis to place human hair upon one's own hair without joining it?

The term "wig" is a modern one referring to artificial hair, and it is not permissible for either men or women to wear it. The Malikis permit women to place hair on their heads without joining it, while the Hanafis disapprove of joining human hair with a woman's hair, but they permit joining it with animal hair or wool.
