Island broken for main

A professor I have has the unfortunate luck to have lost much of his hair in the usual fashion of male pattern baldness, except he's kept his bangs. It's an island of hair broken off from the mainland like Florida after the icecaps melt. I can't think of a less dignified way for the hair to go. I can also see how it might be difficult to shave any hair once one starts to lose hair. You don't want to give the wrong impression to hair you want to keep. It's a tough situation.
