Mid-40’s, just had another birthday, just checked again - still no grey hair.
My dad didn’t start greying until his late 60’s. He’s over 80 and most of his hair is still black.
I was 16, and I was getting my hair cut. The hairstylist was helpful enough to point it out. I’m 26 now, and I’m probably going to need to start dying to cover it soon. Stupid genetics.
I haven’t seen any yet, but it would be hard to tell as my hair is blondish and has many different shades in it. I am 24.
The first I noticed was in my mid-20s.
I’m now 33, and have a handful.
Luckily, they’re all in about the same area (right at the very front of the natural part), so if this keeps up, I can rock the Jason Blood look.
I picked Over 50. I’m 56 and haven’t seen one yet. I guess in return for getting Dad’s thin, straight, fine hair, I didn’t get the gray gene that hit my mom at 40.
I’ve never seen any, but other people do sometimes. The first I heard about were, I think, in my freshman year of high school, maybe earlier. My mom’s friend freaked out and started plucking them out of MY head. My boyfriend claims to have seen one or two, but neither of us really looks closely. I have no intention of covering the grey, so I don’t know if I care. It’s inevitable.
I noticed the first couple when I was 18 (after Halloween… 'Hey! Why isn’t this white spray stuff washing completely out?? Oh…).
Now with a few years to go before 30 when my hair grows out enough I can see several (a dozen maybe?) mixed in with my natural colour. The women in my family tend to go silver early.
I’m told that I was born with a gray hair (among alot of dark brown ones). That said, I’ve had 4 or 5 ever since I can remember.
I was in my early thirties when I noticed I had a patch of grey hair in my whiskers. If I don’t shave for a couple of days I can see that patch and the rest of my beard is sprinkled with others. I have one or two at my temples but they aren’t very obvious.
I’m 41 and still have none on my head, and in a bit of good news may not get any because it appears I’ll go bald first. I have quite a few on my chin though. I’m hoping they’ll keep their current pattern then I’ll have a white stripe down the center of my goatee.
I’m 24, I only have one scraggly gray hair that’s at the top of my head. I hope to be like my mother in that her family grays very late, whereas my dad’s side is the complete opposite. So far, so good.
I tutor one boy who is turning 16 sometime this year but his black hair is peppered with silver hairs already. I thought he just had really shiny hair until I looked closer one day.
In college, ugh, and it quickly became a lot, not just a few scattered gray hairs. I started dying to cover soon after.
I knew my mom had been dying her hair for about as far back as I could remember, you’d think that would have tipped me off.
I probably had gray hair before I noticed it, but my hair color turned mousey in my early thirties, so I was close to 40 before I actually noticed one. But I turned most of my husband’s hair gray within a couple years of marrying him.
34, male. I’m still waiting.
I found my first one the day after the birth of my first child. Symbolic that! 
I’m 53 now though & still have very few grey.
When I was 12, I found a foot long gray hair. By the age of 16 I had white streaks in my hair like Morticia Adams. Now L’oreal and I take care of the problem every few weeks. In the totally-not-fair category my 85 year old mother has less gray hair than I do.
I was 16 and very amused. I guess it was a good thing, since now that I have THOUSANDS of them, they just doesn’t make me feel old.
I’m 42 and don’t have any grays. I’m blonde, so they probably won’t show much, anyway.
Around 21, after my first child I noticed the first gray. Premature graying runs in my family.
Around 33. I started getting a couple at my temples. Now they’re showing up at the top too (I’m 36). The texture is different, all wiry, so I don’t know what I’ll do with it when there’s more.
On the good-news side, no lines/wrinkles yet.
