Is there any truth to the myth of shaved hair growing back faster and thicker?

As a teen, my facial hair grew back faster and thicker as I shaved it, but that might just have been my normal development (i. e., it would have grown faster and thicker as time passed whether or not I shaved).

I’ve been shaving my head for a while now and it’s clear my facial hair grows in faster and thicker than my scalp hair. Is it because I’ve been shaving my face or does facial hair just naturally grow faster and thicker?
