Transplant Hair From My Back

My question is about donor sites. I have a rather extensive amount of back hair and, if possible and practical, I would like to transplant said hair (in conjunction with hair from other, more typical, donor sites) as part of a transplant to correct my scalp baldness. While I still have hair on the sides and the back of my scalp, I do have a lot of baldness all across the top of my scalp, which I assume will require lots of grafts. Can back hair be considered donor hair?

Body hair is not a productive source for hair as traditional sources from the sides and back of your head. Unless you have significantly depleted the donor hair from the traditional source, I would not recommend hair from the body (an experimental procedure of questionable value). I have performed hair transplants on the baldest of men with great results. They have gotten hair from back and sides in each case. For example, see Class 7 Patient ZU from the NHI site.
