Airways

(That's not what we call airlines, it's just them)

kinda mind blowing there is a tiny muscular infrastructure there still, like almost everywhere, just doing nothing most of the time.

but what's the actual mechanism?

something in the follicles?, muscular, or fluid moving around? why does the skin feel tighter? where does whatever the bumps are made of go afterwards, why didn't that mechanism go when we lost the hair - does it serve another purpose most of the time?
