Got my first gray hair when I was 23. At 50, I have a fair amount of it mixed with my dark-brown hair, though I’m still 90 or 95% brown. I call them my natural highlights – I love the way my hair looks.
Got my first grays way early, maybe 14 or 15.
Super noticeable since I’ve usually got long hair, by my mid-twenties I started coloring to cover them, not so much for vanity’s sake but because everyone else seemed much more bothered by them than I was. Sorta like the “talk to ME my eyes aren’t on my chest!” thing, but instead their eyes would constantly drift to my hair.
I’m 34 now and probably 75% grey, just an educated guess since I never let the roots grow out for too long.
Women in my mother’s family go gray in their late 20s-early 30s. I got my first gray hair just after I’d turned 17, and I have several strands on either side of the part in my hair that sprout gray now, but they’re so few and far between I just pluck them out as they come up.
I was 14 when I got my first gray hairs, but only in one small patch, on my front right, starting at the part in the middle, with some in my fringe. I’m 26 now and the patch has expanded very slightly, but in no other areas on my head.
I try to keep it dyed.
I’m 40, and I found my first grey hair when I was about 32, but it was my ONLY grey hair until about a year ago. Now I have about 10 greys, with five or six of them in a group right at my right temple and into my bangs. I have always wanted to have salt-and-pepper hair, just because it looks lively and grey hairs are usually coarser than others - my hair is very fine and straight, so I was hoping fora little “sparkle.” My sister is 35 and has been more than 50% grey since she was 30 (she colors her hair to cover; I stopped coloring when I finally got some grey!)
A small warning for those of you who do color to cover: my best friend used to color her hair a reddish brown to cover grey, but grey hair doesn’t absorb color as well - she’s had to switch to a less vibrant shade, because her greys were dying PINK.
I started going gray when I was pregnant, at age 26. I used to just put highlights in to make it all blend, but it got so bad that now I have to dye my whole head and then put in some streaks. I never let my roots get longer than half an inch or so before redying, but I can tell that the patch by my right temple is now completely white and there are tons of grays sprinkled around my hairline (not so many in the back). I’m 31.
I found my first grey hair in my late 20’s. I have a full head of hair at 39 and it’s about 35% grey and 65% brown…but the brown hairs are losing ground every day. On both sides of my family, all the people keep their hair, but all are completely grey by the age of 45. There is little hope for me so I must adapt.
My husband found his first grey hairs around 32 and now has sexy grey temples and sides on his full head of hair at the age of 42. The part that worries him most is his thick and long chest hair which is rapidly going from black to almost completely grey above his nipples. When it first started turning grey, I can home one day to find him shirtless and from a distance I could see that he had little red whelps all over his chest. When I inquired to what was wrong with him, thinking he had some kind of rash, he proudly exclaimed that he had just removed 78 grey chest hairs. I’m not sure which was worse, the act of pulling them out or keeping count. 
Started with my first grey hairs in my mid-20s and have been completely grey since about age 35 or so. I will be 39 in May. I color it once in a while, though I’m bad about letting it go till all the color grows out! The parts that went grey first are now beginning to turn white.
At least it’s a nice silvery grey and a soft white, though. No brassy tones to deal with!
11 or so. A light peppering now that I’m in my thirties.
First persistant grey hair in my eyebrow back in my late 20’s.
It finally went away and now I have about 5 or 6 at the very top of my head, they have begun increasing.
I am a natural dark blonde so I kind of have to look for them.
I’m 50.
Husband had sprinkling on his temples when I met him when we were in our 20’s.
He is about 60% grey now.
It’s weird, there is a 25 year old at my work who is more than half grey.
She actually has a beautiful curly head of hair though.
I noticed my first one when I was 17. I’m 46 now, and I probably have gone very salt-and-pepper, or maybe completely silver grey, but only my hairdresser knows for sure. My wife is younger than I am, and I don’t want to be mistaken for her dad. It really shows in my moustache, though. At least I still have all my hair. My little brother (now 39) has been losing his hair for years. He doesn’t have much left these days.
I’m 28 and have never had a gray hair. But I do find a touch of gray on an otherwise young attractive woman incredibly appealing for some reason. So any of you 20-somethings/early 30-somethings who are finding some gray, don’t pluck it, don’t dye it, just come by my way and give me a holler! 
I’m 32, and I got my first gray hair last year. Best as I can tell, I have 3 now. It appears that they’ve thrown down the gauntlet against my incipient baldness, and there’s now a race going on.
Based on the rest of the men in my family, my money’s on the baldness…
I got my first gray hair when I was 40. At 43, I now have some gray in my sideburns. I like to tell myself it makes me look distinguished. I had however hoped to emulate my father, who was past 65 before he started to go gray and who, at 72, is still only about 25% gray.
I don’t have any, but this year has been particularly stressful, and there is a slight fear that I may get a few. I rather like the color of my hair, and I’m not ready to start losing it yet…
My boss has greying hair, and it started when he was 5 years old.
20
It started out as a slight gray patch right at my hairline, where I part my hair. My brother had one in the exact same spot (which leads me to believe that it my have been a birthmark of some sort or at least genetic). Now, I’ve got more gray hairs than brown hairs.
Depending of course on how long it has been since the chemo, the friend may find that over time her hair returns to the way that it was before. Certainly after my mother got her hair back after chemo for ovarian cancer, it started white with grey but has since returned to brown with significant amounts of grey. the amount of curl in her hair also has gone from extreme curl to her usual waves.
I got my first grey hair a couple of years ago, and now at 30 am up to about 15, all it one spot. But since little brother has more grey hairs than I, its ok.
As someone with receding and thinning hair, I love to find grey hairs - that means they’re going to stick around.
“Better turncoats than deserters…”
I had my first greay hair at 17. Then nothing happened for years.
Now at 29, I have a few grey hairs in my bangs, and about five scattered throughout the rest of my head. They are long, too. Really stands out because I have very dark hair.
I don’t have grey hairs, I have white hairs. I noticed the first one when I was 27. I will be turning 30 in a few months, and I have a smattering along my center part.
I kinda like them. I am fair. so they aren’t really noticeable yet unless you look closely. I’ve decided that I won’t color my hair, I think it will interesting to see the natural progression. Plus, I like the look of long, white hair.
