> In men, graying first occurs in the temples and sideburns. It spreads to the vertex and rest of the scalp involving the occiput the last.
My graying started when I was 15 and first appeared as a single silver strand at the center of my hairline. At 28, I now have a cluster of them in that center spot, as well as diffusely all over my head, including the occiput. I think my temples and sideburns were actually relatively spared.
Also of interest to me: once in a blue moon, I shed a hair that appears to be reverting from gray back to pigmented -- it's gray close to the tip and black closer to the root. I wonder what factors might cause this reversal.
I have no graying of head hair. But I do have several white hairs in my facial hair. I wouldn't have expected to read that "graying first occurs in the temples and sideburns".
(I also have one white hair that grows inside my nose...)
I know this is anecdotal but I know someone that experienced / is experiencing a similar thing. Several silvery hairs reverting back to pigmented after leaving an overly stressful work environment. She only had a few, but of those few perhaps 30%-50% have reverted.
