I'm with Anne. I never travel without the crushable Pamda hat. There are no hair police that I know of, but there is a lot of Big Hair out there.
I quietly chuckled about the woman who was bi^&*ing about her hairdo being ruined on the Summit. She got the hair done, then went and tried on sweatshirts and was annoyed because the up-do suffered from the experience. Duh.
My personal hair is self-organizing, so I just run wet fingers through it in the morning and wait to see what the results will be be. Good, I sally forth. Bad, the hat.
