Shouldn't this be in your special ed thread, anabol?
First off, renal transplants are a life saving operation and are given slightly more medical concern than your vanity.
Secondly, if you transplanted a scalp of hair you would have a massive scar all the way around the hairline so it would be aesthetically non-viable. Thirdly, any living tissue transplanted from one individual to another (unless it doesn't require a blood supply such as human corneas) is susceptible to immune-mediated destruction. People who receive kidney transplants have to go on lifelong immunosuppressive therapy which comes with a slew of side effects (such as lymphoma!) in order to prevent the aforementioned.
