I am using a natural wart remover similar to ACV, on a wart right on my hairline, on my forehead. I also did a lot of research on do-it-yourself wart removal. In the past I have smothered a wart by simply putting a band-aid on it but can't do that with it being in my hairline. So I am simply applying the "cure" with a Q-tip several times a day. It's been a few weeks and it's going but I think I might also try the ACV.
What I wanted to stress is this will not be the same for everybody. People who have very fast results are lucky. I'm wondering if it may be something to do with the type of wart/mole. As for panicking over it being cancer, I wouldn't. My research indicated that the ones that turn really black and cause a hole, could be, but it will still work with perseverance.
It's paramount to be patient and not pick at it. I still think smothering is at least half the solution but, if you can't, like me, it still works but takes longer. Nothing works in exactly the same way for everybody. For some people (maybe me) it can take months. But I see it working. Just an interesting aside, my father used to do what we called "predict warts". People would show him a wart and he would say it would go away at such and such a time and I saw it work several times. I never had any for him to predict and he's gone now but warts--and people--are funny things. Maybe keep that in mind. But, mostly, be patient and don't let up.
