You can already get hair transplants. Search for Berlusconi/ Wayne Rooney hair transplants and you'll get the details. Unfortunately they can only transplant your own hair so you're limited to the amount of hair you can redistribute on your head but in a year or three you'll be able to bung some eastern European (or in your case Mexican) peasant a few quid and the transplant people can take a load of their hair and graft it onto your head. That corresponds to just about the time I could really do with one. I fancy a full head of hair again.
