I would be interested in why you think you would get regrowth in the procedure you describe?
The mice experiment came up as a surprise to the researchers. The original intention was to develop more efficient transplant proceduces if i read it right.
The transplanted follicles are contained in biopsies of the scalp of 28 men 11 women all of which regrew hair which labels them as
scalp transplants - not just hair follicles transplants.
When they regrew hair, it suggested that nothing was wrong within the pilosesbaeous units; that by merely removing them from the human scalp and transplanting them elsewhere, the units will regrow hair normally - as if nothing was wrong just days before.
We also know that there are several indications that hair growth characteristics are determine by the recipient site -
Donor Dominance Takes a Bow.
In this case, a follicle was transplanted.
However, if that were true, the follicles should not have regrown hair several inches on the mice since mice maintain hair length just a few centimeters long. However, it suggested that hair growth characteristics is determine by the pilosebeceous units.
Regardless of the donor or recipient site dominance assertions, the outcome of the mice experiments suggested that the root cause of male pattern baldness is being induced from OUTSIDE the pilosebeceous units.
The association of male pattern baldness with several serious diseases and conditions supports the suggestion that male pattern baldness is being induced from OUTSIDE the pilosebeceous units. It is also obvious that whatever is causing male pattern baldness, it has no effect on the 'horseshoe' area (back and sides of the head).
Therefore, if the hair folicles are capable of fixing themselves, as shown in the mice experiments, transplanting balding scalp to the 'horseshoe' area should allow them to fix themselves as well.
However, only an actual procedure can confirm this.
These are the reasons why I never read any argument or study which tend to focus on the scalp particularly within the pilosebeceous units or the follicles.
