tw5, as mmhce said, it might help to post some pictures.
Consult with several reputed doctors to get a diverse set of opinions. Also, a few docs are successfully able to transplant body hair to the scalp (there was a recent posting where someone "extracted" hair from the chest and armpits to transplant to the scalp). So if you're constrained by scalp donor hair, body hair might be a suitable alternative.
Good luck!
