Right on the money. He might have been a vanity thing when he was young, but who among us isn't guilty of the same thing? As for Gates McFadden, I assumed she wore the wig in the first season when her onscreen hair looked thicker and redder. When her hair looked more strawberry blonde and was finer in texture I figured it was her own. And I'm pretty sure the Nathan Fillion toupee thing is just a joke.
