Doesn't look like there's too much difference, but it can be hard to tell from pictures. so don't despair. Are you using finasteride? You realise that without it you will continue to lose hair at the same rate you have been over the years? Sure, the minoxidil will grow some new ones, but it may not be enough to replace what you're losing.
I think a dht inhibitor like finasteride should be the corner stone of any attempt to reverse/halt/slow male pattern baldness. Build on it by all means (adding minoxidil etc), but if your hair loss is aggressive then I can't see how you can win the fight without it. Hell, if the hair loss is real aggressive you might want to consider the king of dht inhibitors, dutasteride. I'm giving finasteride a year, if it doesn't work then I'm seriously going to consider the mighty dutasteride.
Anyway, good luck!
