How come all of your hair doesn't grow at the same rate?

[NFS4]

Of course the hair on my head grows and grows and grows until I get it cut...that's obvious...

But why doesn't leg hair, arm hair, etc. grow at the same rate? If I were to shave a spot on my leg, it would grow back in a few weeks and stay the same length that it was when I cut it.

Then on the other hand, if I have some stubble on my face and I shave it, it will grow back to the EXACT same length that it was before I shaved it and will not grow any further. Same goes for my mustache.

What's up, is hair pre-programmed? 😉

Hair is pre-programmed.

I think this question was asked on Straightdope a while back. Don't remember the answer though.

LOL, it's just something I've always wondered about.

And no, I'm not high. Never have been, never will be. Hell, I've never even smoked a cigarette before

I do. If you have a problem with it, find another thread to crap in.

How does body hair know it's been cut and grow back?
Why does head hair grow indefinitely but other body hair doesn't?
