I have one grey hair.
In fact, I have had my one grey hair since age 13.
In general, my hair is thick, wirey, long, and messy. There is a considerable amount of it. I shed profusely, especially after I wash it. When I brush it all out completely, I have to clean the brush (using scissors to cut the hair out) a couple times before I'm done. In the end, the pile on the table could make a small wig, that is how much I shed. It grows fast.
I usually tie it up in a strange loopy ponytail-with-the-ends-tucked-in, which I devised a few years ago, taking it down only every few days to wash it. By day 3, the tied-up pseudo-ponytail-bun-thing is looking pretty ragged, which I like to think of as "having character."
My hair clogs drains. It backs up sewers. No lie, when I was 7, my father had to dig out the sewer in our backyard only to find that it was clogged with MY HAIR.
But my grey hair is different from the rest of my hair. It's easy to spot... right in front, just to the left (from my POV) of the widow's peak. It always seems to stick out a little, its natural wave just a teeny bit different from the surrounding hair. It catches the light nicely.
I've always liked my one grey hair. It's different from all the other hair on my head. It never comes out in the hairbrush or the shower. It seems to be a hardy hair. Stuck in the scalp but good.
Some day, if family genetics continue on track (so, in my 40s), I will have more grey hairs. But this one will always be the first, and the oldest.
I am inordinately proud of my one grey hair.
