I would avoid shaving the area if you haven't been regularly shaving. I have kinda hairy arms and the tegaderm wasn't sticking very well/peeling easily there. I thought it would be a good idea to shave around the wound to make the area. Well for the next 2 weeks I had enough ingrown hairs on my arm to make me look like I had leporcy. A pair of clippers is a much better move if that area isn't shaved.
