Oh my God! You're already getting gray hairs? Wow. I'd hurry up and marry your boyfriend because I don't see a whole lot of other interested romantic partners - especially once they see those gray hairs. I'm really sorry.
You might get interest from older men. Older, fatter, balding men. With funny smells. It's such a shame - that your youth is vexed by this harbinger of old age.
You could dye it. Definitely, but then you'd constantly have to re-dye it every two to four weeks and people notice those roots and they'll talk.
It's not your fault, dear. It really isn't. It's Mother Nature letting your perspective partners know that you're unhealthy and therefor unfit to be a parent.
I would tell you not to worry about it, but I would worry about it and that would make my advice hypocritical. Looks like, unless you like quiet, lonely, boring nights at home, watching TV and making baked goods for your younger, livelier co-workers, who are having the time of their lives because they're not gray, your life is pretty much over.
Now with extra singles!
