I’ve heard that gray hair is the result of a loss of melanocytes in the root of the hair (the cells that make the keratin). The loss of these cells could be the result of poor health, diet, stress, age, or is random. In other words, the molecular aspect is known, but the true cause is not known because there are too many environmental variables.

I don’t have any gray hair. Mine are all white, and every time I get a haircut there are more and more.
Who’s hair it that?

mine are growing more and more populous, and because they’re wirier than my other hair, they insist on sticking out from my head at a perfect 90 degree angle. it’s quite sad, really… i’m only 26.

as total coverage seems to be dropping, I’m finding I’m less selective on color…

I’m pretty sure that my kids are responsible for mine…

I may be 30 but I’m neither balding or graying. My eyesight and hearing is starting to go but thank goodness for small favors.
Whose hair IS that?
