In reference to the "hair grows back thicker and darker after you shave it" myth, I would like to ask anyone to take a look at any kid going through puberty. When they first get their facial hair, it's thin and soft. Once they shave it, it comes back thicker and more brittle.

I had a friend back in my high school years who refused to shave, even after he started growing facial hair. It was very soft, thin, light-colored, and ugly-looking. We eventually pinned him down and shaved it off for him. *evil grin* Finally, it grew in normal-looking, dark, and thick.
