You can be quite negative donewithit... He isn't slick bald, apart from that line at his crown, he probably still has vellus hair where it's thinning and that can be restored to full terminal hair. Assuming he is within the purported 88% for whom the big three works, he probably has a good chance at moderate success in regrowing hair. Maybe not full perfect head of hair, but I'd say decent-good coverage and appearance.
