Hi madmadman,
unfortunately, even a 'simple' scalp transplant from a HLA compatible donor would force the recipient to a lifelong immunosuppressive treatment to avoid graft rejection.
Together with all the well known side effects (infections, EBV-lymphomas, etc.).
Baldness is much much better, believe me.
