The Mystery of Grey Hair Solved
Thanks to Google and the Mayo Clinic for enlightening me on how hair turns grey....
So in other words a hair may gradually turn grey because less pigment is produced during the life of the hair, or a hair may fall out and be replaced by a considerably less pigmented hair. So technically it can happen either way it can turn grey or grow grey.
Gray hair is typically a result of natural aging. Pigment in the hair shaft comes from special cells at the root (base) of the hair. These cells are genetically programmed to make a certain amount of pigment (melanin) at specific ages. At some point in the aging process, these cells make less and less pigment until the hair has very little pigment. White hair has no pigment, and gray hair has some but not as much as a red, black or brown hair.

It's official I am a weirdo. I mean who spends time worrying about how hair goes grey?
