Me too, the wax + helmet combination makes my hair stick flat to my head. Lol. Maybe that issue will be over sometime soon-ish since I'm growing out my hair now hahaha. Last year I just did not do my hair and leave some wax at work so I could put it in over there instead.
I think one-piece suits look nice, but I know they are a burden. I borrowed one from someone a while ago (not to ride myself, since I did not have my license back then - I was a passenger, I did not have proper equipment of my own and we drove to Belgium). That's also when I decided that I would always get a two-piece if I ever were to get a license myself hahah. It took a proper while to put it on, and afterwards, I felt like I was stuck in it since taking it off wasn't very easy either haha.
