Transplant a balding follicle into a donor area = it still balds.
Transplant a donor follicle into a balding area = it still doesn't bald.
Sorry if I sound dismissive but this is a huge elephant in the room.
I actually do suspect that the recipient area can affect "donor" follicles over time. It's well known that if you transplant body hairs into the scalp, they will gradually start to grow longer (than in their original body location). They seem to reach about halfway between their original condition and scalp hairs.
The transplant community has embraced that fact and now they sometimes utilize body hairs on the scalp. But nobody ever seems to bring up the other half of what it implies - if the recipient area skin affects the traits of transplanted hairs, then it could theoretically cause thinning of "safe zone" donor scalp hairs too. Sometimes guys with older transplants (decades) will complain about long-term thinning of the donor grafts - maybe that is all explained by natural "donor thinning" from old age or maybe it isn't.
This stuff is all interesting, but it doesn't outweigh the elephant in the room. Most follicles generally behave like their balding traits are genetically programmed.
