Long hair: More migraines?

Has anyone else had fewer migraines after cutting their hair?

I got my hair chopped off dramatically this week, and I've noticed I've had fewer migraines since.

Before the haircut, I started to despise my hair. Anytime I wore it in a bun, I could feel each individual hair being tugged on; my scalp felt ridiculously sensitive, especially during a migraine.

Maybe it's coincidence. Maybe it's less weight, less tension, or not wearing it up all the time. I don't know.

Has anyone else noticed this after a big haircut, or is my brain just giving me a temporary break?
