Somebody help me out. At what point, exactly, did Greg Brady hair come back into style, and why wasn't there some sort of announcement?

When I was in high school in the mid-80's, you could've gotten killed for showing up with Brady Hair. It would've clashed with everyone else's mullet. But I work next-door to a high school, and I'd say about one out of every four boys now has a big, puffy, Greg/Mike Brady perm. I know style is cyclical, but aren't there at least a few things that are so bad that they never come back? And if so, shouldn't this have been one of them?
