Okay, I'm not entirely sure that I ever have a right to give any advice on this topic. I am 27 and can grow a full head of hair. I am 100% BBC. Most people think that I am balding, especially since I am blond and I have virtually no shadow. Some people even ASK if I am balding and that's why I shave. I just tell them, "No, I have a full head of hair, I just love being bald!" You can ALWAYS use that as your line, bro. No one NEEDS to know that you're balding. Make it your secret. Keep shaving the dome, think about the guys out there, like me, that shave just because of the look. Hopefully that can give you the confidence you need to get out there and embrace yourself. I can say that I think transplants are a bad idea, no matter what. I just don't think it's worth it, no matter what the outcome. In the long run, I think everyone here will agree with me, you'll regret it.
Whatever you decide, I wish you the best of luck on your journey to happiness. Happiness is something that everyone deserves, no matter what they feel they need to do or change to make that happen.
