I'm not sure anymore what to do about gray hairs.
The first time I saw one a few years ago, I immediately yanked it out and made a blog post about OMG I'M SO OLD I HAVE GRAY HAIRS NOW. Now I see one every month or two.
One problem is that my hair is dark but not uniformly so. Meaning I do have some blondish strands. So occasionally a blond hair will catch my attention and I have to isolate it and examine it to determine if it is in fact gray or blond. I feel slightly ridiculous while doing this.
I realize at some point, I'm going to need to stop yanking out gray hairs or else face baldness. I'm just not sure what the critical amount of gray is where it's better to dye than yank. Also, I always thought I'd be the kind of person who would totally be okay with having gray hairs, but I guess no woman is excited about looking older.
