Long hair affect sprinting or long distance running?

I'm a runner and i was wondering if long hair does affect running or not? there seems to be no clear cut answer because i've seen many sprinters with long big hair or cornrows/dreads etc and many bald but no mid length hair. Also does it affect in long distance running? like 5ks, 2mile, 1mile races? i've seen both long distance and sprinters with long hair and short.
