At least you can dye it and cover it up, I have a friend who not only has had the grey patch since she was in her teens, she is now 31 and starting to thin and go a bit bald. It is unfortunatley normal and common to start getting grey hairs in your early 20's. Even if you pluck they will grow back, it is that particular follicle that can no longer hold pigment so the next one that grows through will be the same. Dye it or pluck it if you want to, whatever makes you happy and remember your only as old as you act. He he he
