Prehensile Hair

+0
−0

As I'm sure anyone reading this knows, our body parts move via the brain signaling the appropriate muscles to contract or expand. Now, for hair to function the way it does - its texture, malleability, etc. - it doesn't seem plausible for prehensile hair to happen with a humanoid with muscles all the way up and down every strand of hair. Plus, that would probably result in a lot of blood gushing every time you got a hair cut. So how else could prehensile hair be explained while still rooted in hard science? (Or, more generally, is it possible?)

Specifically, I'm looking for a way to not only move hair, but also to do so with enough force that the user can grab onto something with it.

EDIT: There are a ton of good answers down there. I accepted the one that worked best for me, but for anyone else who wants a go at this, that's not the only one that looks like it works.
