I just did 3000 or so grafts about 2 weeks ago and went back to work a week after. Nobody noticed anything and I work in a white-collar environment (can't wear a hat) and work directly with about 200 people. I feel that you should not change anything with your appearance post-op (like some guys do with shaving and the such) as to only draw more attention to yourself. I think this is more of an issue with people you might not see on a regular basis then the ones you do everyday. Using the sun burn approach or that you hit your head on something is good too.
