FrenchOnion: If a man's handsome, a man's handsome. Say a man has what would be considered by many to be thick hair. Should he pull it out? I'm opting for no. I may be wrong, but I'd rather he didn't. Regardless of what people may think of him when they see him. It would seem to me that the fellow would follow the same social guidelines as most of us do, i.e., comb his hair daily, have a nice cut regularly, shampoo and otherwise clean. I, personally, haven't picked up on a social stream that says, when a man's hair get's this thick then he should cut his hair shorter and more often and should bald faster than normal or what not. I would think this would apply to all physical features: if a man has a particularly attractive face, he should wash it the same as everyone else.
As for "old people", families, and children staring in the park, I had no idea they would do that. If they did stare because of your thick hair, I'd smile back.
