Scanning the circumference of the earth taking notice of human hair variation; we can count one major dichotomy in human hair shape: that of loose hair that hangs down towards the earth and that of hair that builds upward spherically.
In the rest of the world where the air isn't heavy enough to resist streaming motion; hair evolved in order to mimic this streaming motion.
TEST:
Can you tell the difference???????
One picture is in India where the hair mimics a streaming movement and the other picture is in Africa where the air is heavy enough that their is no streaming movement.
In Africa where their exists extraordinarily heavy air; enough to resist moving in a stream-like fashion we find hair that mimics a contained, non-streaming and cloud-like motion.
In the rest of the world where the air isn't heavy enough to resist streaming motion; hair evolved in order to mimic this streaming motion.
