Metaru is right-- head swaying/hair movement is actually unrealistic. Our head is typically kept very still while walking due to our vision being focused on something in particular. The only time our hair might move is if we were running, and if we wanted our head to sway involuntarily we would have to be running very very ferociously. Even then, it's hardly possible to run fast enough that you'd actually lose control of your head, even if you were running in a panic you'd still be intensely focused on where you're going.

That said, in animation, it is not incorrect to make the head sway as such. It can add a lot of character to an animation. I tried to do so here and didn't exactly do a spectacular job, if the critical response I've been getting from various places is to be trusted. The movement of the hair was not made obvious enough, so I will mess around with it more.
