Ive heard from many people that shaving more often will make facial hair grow back thicker is this true?
I also heard that. Don't see how it can be true but you never know...
No ,it's a myth, just as trimming your hair to make it grow faster is a myth.
Not true. It just appears to be thicker because the hair shaft is no longer coming to a fine tip after you cut it. It just looks thicker/darker because it comes to a blunt end.

Shaving for a thicker beard and trimming for longer hair is like having sex to promote virginity. Total nonsense! Mihnea's explanation is the most likely source of this ridiculousness.
Let it grow! You won't be sorry!
