A skull cap helps and cuts down on the embarrassing walk. However, The best thing to do is keep some hair stuff in your desk or a small amount in your bag and fix it up when you get there. I am fortunate enough to have a shower at work so I don’t worry.
I love helmet hair. If anyone comments, say “I meant it to look like that. I spent almost an hour getting my hair to look JUST LIKE THIS!”
Not a day goes by that I don’t give thanks that EPA lets me use their bike room and GSA lets me use their locker room and showers. I can deal with the mildew and mold. I spray a path of bleach between my bike and the shower every week or two. I like having a place to shower in the morning.
