Different colored hairs in my beard

I’ve got you all beat.

My hair is blonde (or ash-blond, a shade darker in wintertime), and I have red sideburns, a blonde moustache, a red and auburn beard. My chest hair is dark brown, and moving further down it’s eventually gets to an auburn color.

Oh, and there’s one little hair that grows jet black on the top of my head. It’s really thick and wavy, while my hair is very fine and limp.

My son is South Korean. 100%. He has that beautiful THICK jet black hair.

Except for two hairs, at different places on his head. Which are pure white. I need to look into that…
