Sounds like you're nicely on the mend. It wouldn't worry too much about going back to work in 10 days. I actually went back (office environment, no hat) 2 days after the procedure. Yeah, there was some redness and some red specks under my existing hair, but nothing too noticeable.
If I remember right from my last procedure, you'll have some dandruff-looking shedding at around day 7, but gone quickly. With all that thick native hair you have, should be no trouble masking the stubby new hairs until they shed in the next two weeks or so.
