One day, I decided to cut it, but then went outside and sanded it down to a slightly less-than-normal thickness out of frustration. I noticed that the outside looked normal-ish, but inside it was pithy, like old dead wood, small hollow pockets with brown streaks.
So, I mixed up some iodine I had, some hydrogen peroxide, and some 500 ppm colloidial silver. It was 60% iodine, 20% hydrogen peroxide, 20% colloidial silver. I would paint it on in the morning a few times so that it soaked in nicely, then put on a bandage over the nail or a "finger cot" (like a condom for your finger), then take it off in a few hours. Then, when I got home, I would paint it on several times again, but let it air dry.
The nail started to grow back normally from the base of it, but I moved and was unable to continue to the current living arrangement for a year. It reverted back to the old thick nail by the end.
I am now able to continue my earlier treatments, but didnt figure that you would want to wait a year or two to find out how it goes. It takes about a year for a nail ripped off to grow completely back in (dont ask me how I know ;), so if you do this, I would continue for 2 years to make sure that it was completely gone, then a periodic treatment, once a week or twice a month or so, to make sure that it doesnt come back. If it is thick, even possibly not, make sure to sand it down quite a bit, so that it can absorb down into the nail bed better, since nails arent the most porous of substances. The key is to get it into the nail, as if you put it on and then put on socks that absorb the liquid, it wont go into the nail. That is why I used something to keep the solution from drying out and not soaking in.
