Summer hairdos for guys presumes you have lots of hair. While I escaped the fate of my grandfather, who was almost entirely bald on his wedding day in his early 20's, and my father who was likewise by 35, my hair has abeen almost entirely grey since late 30's and is now very thin and fine. I'm told by my wife and sons that there is now a large bald patch on the top rear of my head, and I do feel a lot of smooth skin there, but since I don't see it in the mirror, I don't believe it. But a summer do might reveal what I really don't want to see.
