I have started a new thread due to the overload.
Looking at the pics I just realised that there may be a significant error of the surgery that goes beyond bad luck and may demand litigation as falling below the duty of care.
It looks like a flap was performed but in contrast to the standard for this work, the flap was taken from the very boarder of the balding area which, I believe is a prohibited area for the flap donor. Worse still, the flap taken on the side of the discoloured area was taken at a totally diferent angle such that on closure of the deficit the bald scalp was pulled down into the donor area. In fact on that side any undermining or expansion must have been performed such that the bald tissue was pulled down rather than the hair bearing skin pulled up.
An expert could discount this or validate it since, to me, it looks very clear.
