Most interesting. I was 11 when our dark-haired family MD went to serve in WW2. When he returned his hair was white.

I can agree because I knew it. Almost half of my hairs turned grey 3 times. It always occurred after significant stress which was 1995, 2005, 2012. However, I reject the general assumption that the change in natural hair color is permanent. Most of my hairs turned brown again after a few years without stress.

I will take a look up my nose, and see if I can work out what color my hair is these days.

So, if I grow mice hair on my head, and if I worry,,,,,,,,,,,,,I don't get it.

In my first marriage i started to get the usual friar bald spot and knew it was stress related. After we broke up the spot disappeared and now plenty of hair.

Wow! This runs counter to my experience. I have had extreme stress in my life, but the majority of my hair is still brown at the age of 66. I am gradually going gray in the same pattern as all the women in my family.
