I´ve seen bald, ugly, short, acneface, pale, redhaired guys having relationships in their 20´s with average and goodlooking girls, in fact most young guys I meet at work are in relationships and when their relationsship break up they get a new one.so its over bald in your 20s?
The thing is when you get older you get a wider spectrum of girls that are available. However with your attitude it´s probably over, if your hair is the only thing you think you can attract a girl with I´d say you are in trouble.
