i've got an office job too and had about 2000 grafts in the front and lowered my hairline a bit.
I had 3 weeks off but then ended up taking an extra week off sick in the hope i could pull off a combover to conceal the work. It worked ok with a little bit of toppik in the front(to stop bright lights shining through). I just wear a hat outside to stop the wind blowing my hair about. This seems to work ok maybe you could do something similar if your hair is long enough. My strip scar is still a bit red and the recipient area has not much going on at the moment. This at about 2 months 3 weeks. Hope it goes well whatever you decide.
