When did you first get white/grey hair?

I’ve found a few hairs coming in white recently, and I’m curious when other people first started noticing them. I feel like maybe it’s stress because I’m so young and they’re not grey at all, but maybe I’m actually just at that age. I was planning on dying my hair soon but I also kind of want to rock white if it keeps coming in like that- so thoughts on that would be appreciated as well.
