#1: Does tying your hair back give you headaches?
I used to wear my hair up all the time. When I started working I would get frequent headaches. Could've been more related to staring at a computer screen for 8 hours a day than wearing my hair up. Anyway I usually wear my hair down now and I notice when I wear it up I get headaches, even when it is pulled up loosely. Could be a subconscious thing.
