when I was young I wanted red hair because my great grandmother had red hair and hers went this GORGEOUS snow white color.
When I was a kid, I hated my red hair - the other kids teased me calling me Woody Woodpecker. It wasn't until my college years that I appreciated my color. Ever since I was about 12, I would get an occasional pure white hair or two. Right now I have a few white hairs at the temples - not gray but pure white and same softness as my hair. I like them - adds character and definition, IMO. Only 2% of the world population is natural redheads.

And when the grey creeps in, I put the red back. All four of my kids and all 7 of my grandkids, have dark brown hair but in the sun, you can see the red. I just hope that someday they embrace it too.
so yeah I've purposely done that...
