Why doesn't the hair, other than that on your head, continue to grow?

I’ve been wondering this myself.

I am willing to say that this is the single best question I’ve ever seen on Fluther!

I’ll speculate in order to not put a “dumb” post: probably because of “scalp.” I would assume that there is a difference at the root of the hair—on the head, it doesn’t just grow from skin. On second thought, facial hair continues to grow. Yet, nose and ear hair doesn’t as far as I know.

You guys obviously haven’t hit your forties. LOL

Similar thread from 5 months ago, hope this helps.

I think all your hair continues to grow. I believe that the hair on your arms and legs falls out over time as it gets replaced and you never know it. But then again, I could be wrong.

i’m pretty sure i agree with astrochuck.

AstroChuck is right. All hair grows continually, but each hair will fall out in a set amount of time. The lengths of thees cycles varies according to where the hair is located.
