Bald? With long locks? Is a man's hair (or lack thereof) a deciding factor for you?
Personally, I'm always a little weirded out when I encounter a man with hair longer than mine (shoulder-length or below). I also find a longer look, like McDreamy's, only suits a small number of men over a certain age. The majority of the time, it just seems like they're trying to hold on to their youth and/or hide a bald spot.
A shaved or short(er) style, however, is a sign of confidence in my books and a look I've come to love. There's just something so masculine about it.
