Thankyou for the link, this is precisely the issue i'm concerned about reguarding dermatch. I think in that particular patient the method used during the procedure may have created the larger pores that made it easier to get clogged and potentially affect growth. I think for me I will not use it for a year after my procedure to be safe, and then if I do use it reguarly I will study my scalp to make sure there is no build up like that, as I would be concerned to have my pores clogged and lose hair due to it, but I suspect that with light use, good washing, and matured transplanted hair, that this should not happen.
The reason I mentioned my bangs/hairspray suffocating my grafts is because i've read that wigs have been shown in some cases to stunt the growth of hair transplants, and although my fringe is my own, the same may apply. I was thinking keeping the bangs back at night may be a sensible precaution, although i am probably being paranoid about it!
