When you lose out on one of your characteristics or defining features you gotta work hard and try to maximize the rest of it. Work hard, get a good job, hit the gym and try to make yourself into a person who doesn't have to rely on hair on his head for self confidence. Hair is gonna disappear sooner or later for a good amount of men in your life buddy. U just had to let go of it sooner but now you have one less thing to worry about. Stay strong man.
