Greg Beato defends rugs:
[W]hat truly distinguishes the toupee from competing hair restoration solutions — and perhaps more important, what makes it feel so timely — is its improvisational nature. Hair restoration medications might not work, but even worse, they might work — in ways you don’t want them to. Propecia, for example, may cause irreversible sexual dysfunction or make you grow breasts. Hair transplants may be the most economical and trouble-free solution in the long run, but what if your surgeon’s having a bad day, or even a bad few minutes, and you wind up with doll hair for life?
A toupee presents no such risks.
