Question, in which I have one

Just out of curiosity, for the combover sporting man, how long does it take to grow out said combover? Five months at least, right? And what on earth do you do with the shock of hair you grow to cover your head in the time that it's not long enough to go from ear to ear? There's not really such a thing as half a combover? Or two thirds a combover, right?

It's all a mystery.
