i dont think that it is one nail growing on top of the other...i think that your nails are maybe brittle like mine and the top layers of the nail crack and 'peel' off so it appears to be one nail on top of the other...try some vitamin E pills or oil...use clear nail polish hardner...you can get it from Wal-mart...sally henson is a good brand...good luck
on a human??
