I don't have super long hair but I have enough lol And usually if I wanna impress a guy I don't tie it up I leave it down because it usually looks hotter like that..haha
Ok for the more effort thing it depends, putting it up nice, depending on how good you are at it, won't take as long as styling it down..when its down you (or at least *I*) have you fuss with it till its just right and then there's the weather aspect like wind and rain and everything lol...when its up you don't have anything to worry about..so actually LEAVING it DOWN is Wayyyy more effort than putting it up..
If I want to impress a guy, I leave it down. It takes more effort making sure its straight with no flyaways and when I'm in school or just don't have time to do my hair, I tie it up its less effort. guys like the hair down more too I thought.
I do, I have very long and thick hair. I will go for high bun, pony or a braid (Lara Croft style), but never on first date. It is too intimidating. Girls think they are more attractive with loose hair, I don’t think so. It gives a stylish and sleek look.
