Most Helpful Girl
They don't have to be unattractive. Its all about how they feel about it, and how they deal with it. If they don't let it hurt self confidence, and they don't let it change the way they act. They can be the same as a guy with a full head of hair.
If it bothers him that much and he would look good with it he could always shave his head. Some guys look really, really good like that. But I'm a sucker for extremely short hair on guys :)
