Regrowth note: Other pictures were shown (including the one shown on our main propecia page) which in our opinion show great improvement for the front. Even looking at their pictures showing no improvement above, if you look at the part in the hair it looks like the part is smaller and the hair denser. Probably an example of their conservative judgement of the photos.
