Had some rogue grays since I was freshman in high school. Used to be really self conscious about it but then I met this dude at school that was a year older and had almost a full head of them. So by comparison I didn’t feel so bad. And he was a cool dude and nobody ever brought it up so I figured I was stressing about nothing. I’ll be 32 next week and while they have multiplied, I would still say my hair is mostly dark so I’m not too concerned yet
I’ve probably been getting grays since my late 20s, it’s in spots where I keep my hair short so they aren’t too noticeable
A friend of mine (he's 31) got no grey hair but his beard is fully grey on the chin and it looks weirdly cool
