I think it's a shadow. I tried to reproduce the effect, and couldn't do it with transparency settings. (You get a sharp line, much farther up, not bands across the whole forehead.)

However, moving a light so that it was overhead produced lines. Turn off "cast shadows," and it's gone.

Try increasing the size of your shadow map on the light that's overhead. I tried four times the default size, and the lines vanished. Smaller might work, though - didn't try it.
