Here is a study in which dark hairs from the back of the head are moved into areas affected by greying. The dark hairs have stayed dark in one patient TEN YEARS after implantation…showing the hair retains its characteristics, its resistance to Male Pattern Baldness INDIVDIUALLY based on the area of the head that it came from.

The concept of ‘donor dominance’ in hair transplantation
refers to autografts which continue to maintain their
integrity and characteristics after transplantation to a new
site. Such hairs may retain their original texture and rate of
growth. Hair transplantation for patients with androgenetic
alopecia rely on this concept of donor dominance for a
successful and long-lasting result. Recently, the concept
of ‘recipient dominance’ in hair transplantation has been
debated. In a study of patterns after hair transplantation to
the scalp and eyebrows in patients affected by madarosis,
Lee et al found that the greying rate of hairs approximated
the recipient site rather than the donor site.
We report on the long-term maintenance of follicular
pigmentation in transplanted hairs. We describe two
patients affected by both androgenetic alopecia and hair
greying in the transplant recipient area. They were given
autografts of normally pigmented hair follicles harvested
from the occipital area. More than one year posttransplantation,
their donor hairs have remained pigmented
long-term, despite being implanted in scalp affected by
greying. In one patient the pigmented hairs have remained
stable for 10 years. As the process of greying usually affects
the temporal scalp .rst, then progresses onto the vertex
