Dr. James Harris, through his assistant Thomas Ortiz, answered a hair transplant question of mine about donutting times on another site (HS). His reply took a few days, and must have been up for a while, as Ive just seen it.
I found this to be particularily instructive:
"In my previous life when both jugular veins had to be sacrificed
for some reason the head would swell to enormous proportions and none of my
patients ever experienced hair loss."
Here is the whole reply in context-----------------
"Sorry this is late benji from Dr. Harris. He just answered it.
"Tom,
Sorry, my filter has been sending your e-mails to the junk file.
Donutting typically becomes evident during the regrowth (6-12 months) period
after transplanting. The most logical explanation based on this observation
is that something occurs after transplantation that affects growth of
follicles in a certain position in these larger grafts. The most logical
explanation is the lack oxygen diffusion during the grafts early
revascularization process.
The scar maturation during subsequent years may have some impact but it is
probably a secondary consideration. I doubt that after the first year
changes in lymphatic flow have any role. If they did all the grafts would
start puffing up. High lymphatic pressures have never been shown to cause
hair loss. In my previous life when both jugular veins had to be sacrificed
for some reason the head would swell to enormous proportions and none of my
patients ever experienced hair loss.
