Braces and Invisalign are partially covered by many insurances but it can get tricky. Check with your insurance provider. I paid for a good portion of mine out of pocket and had some covered by insurance.
I can't speak on the skin surgery.
Hair transplants vary wildly based on location, doctor, and technique. IIRC you're a black guy so that would be another consideration because typically black people's hair has a different shaped follicle. It is possible to go the Turkey route but generally you get what you pay for, so buyer beware.

I remember you posting pics. Have you grown your hair out any more or still rocking the buzz?
