Why does a facial hair, that is "Pulled", "plucked" or "Tweezed" out, grow back?

The follicle in the skin grows the hair. If you pull out the hair, the follicle grows another one.

It's not like pulling out a plant; there is no seed or root. The hair itself is not really even alive; just the follicle is. 

EDIT: If you pull out a hair by the root, the white bulb you see is made up of follicle cells, but the hair-producing part of the follicle is (usually) not damaged.
