What's the purpose of the hair on your head growing indefinitely?

Asked by Spargett (4415 points) | asked January 2nd, 2008 | 3 responses

Why just your head (and face for men) and not other parts of our body? What determines when the hair stops growing on other parts of our body. How does the follicle know when the correct length has been reached? Even if you cut it, it’ll still grow back to the same pre-determined length.

Are there any other animals who’s hair will grow indefinitely if not cut?
