My hair grows uneven too. The side that grows faster is also a lot thicker. I don't know if the retarded side grows slower because I sleep on that side, or because of damage I got from micro braids ealier this year (2 different people braided a half of my hair, and the side that's thin now had a lot of breakage, like I could see the braid pulling the hair from my scalp in the front) But then, come to think of it, the retarted side of my hair has always been more prone to breakage... Hmm...
