Anyway, we separated the nail from the toe bed somewhat so we could get the neem oil in there. It sounds disgusting but separating the nail really did the trick, I think. The Neem oil settles in there and will stay for days if you don't wash it out. Within a week the fungus and black was nearly completely gone. It was only applied 3-4 times. There is still a dark spot on one nail which is more red than black now, but I feel a couple of additional applications of the neem oil should finish it off nicely. Two thumbs up!
