My hair is very dark brown and I am getting close to the big 4-0 and just started to see the grays these past couple of weeks. For about a week it seemed I was finding one each day! My hairdresser told me NOT to pull them out. She said that by pulling them out at the root, it will cause them to grow out in a "sticking out" fashion. She said that instead, I should clip them very short with scissors. This way they will grow back in more naturally like the rest of my hair, rather than poking out like beacons. We'll see how that works . . .
