@blackle not enough to make the hair greasy, but it'll make it so the scales of the hair slip better. then just kinda rub the sides of the knot until you can get some claws into the middle of it, or the top/edge, and just keep doin' til the knot comes undone
@blackle yeah, if you can get a real real fine toothed comb/pick you sorta can, you gotta just try inserting it in the knot, but its often not worth the effort
