Pet peeve

Minor cinematic pet peeve that I need to get out of my system:

Why is it that women in action movies, who KNOW they are headed into life-or-death combat, do not take a moment to tie back their long hair? Or even cut it off?

I currently have long hair and enjoy having it, but it frequently gets in my way, so I always tie it back or put it up. If I were headed into a combat situation I would shear it all off to an inch long. I would not want to die because my hair got into my eyes at the wrong moment.
