crwitt,love your hair! that is exactly how mine came in, more and more in the front, then eventually some in the back.
now i am about 85% white/gray, and the bottom back of my hair which is usually covered is totally black.
my sister's came in fairly evenly, nice salt and pepper. but i think for most people the front first, then the back.
