I prefer my hair all at one length. For me, layers were just a pain in the butt. Granted, I've only cut them in once at somewhere between chin and shoulder but I disliked them almost immediately. I've pretty much grown my hair out to the point that any "layers" have blended in with the rest of my hair or been chopped off. Oh, and the layers caused lots of split ends. All up my length. I vote no layers.
