I have read that the reason shaving seems to make hair thicker and stubbier has something to do with the thicker hair taking longer to grow. The baby hair may remain as fine all one's life, but be slowly hidden under the slower-growing thicker hair?

Shaving doesn't actually make hair thicker and stubbier, it just takes off a hair's tapered point and exposes a cross section.

I'm pretty sure not. While I don't examine the hair in my hairbrush hair by hair, it all looks to be of about the same thickness.
