Most of the time I can’t really tell that the actor’s are wearing wigs/extensions. I think the hairdresser does pretty amazing with Regina’s hair, going back and forth between her nature short hair to the Evil Queen’s longer hair. I think the most obvious cases of wigs, to me anyway, actually dealt with some of the men. For instance, Shepherd James at the beginning of “The Shepherd” and then Jefferson in the Fairytale World.
