I have two toenails on each foot that have fungus infections. I tried Vicks and it didn't work. In desperation, I bought a product for restoring problem nails made by Varisi. It cost over $14 for 1/2 ounce, but the box said "product performance guaranteed or your money back." I used it exactly as directed. When it didn't work, I foolishly bought a second bottle thinking that maybe I hadn't given it enough time. By the time I finished treating with the second bottle, the fungus was still there and the nails were an ugly reddish-brown. What had looked bad now looked terrible. I sent an empty bottle along with my receipt back to the company, which they required to get a refund, only to find out that their refund policy is as bogus as their product. I'm going to try vinegar next. I know it will take months to work, if it does. I went to the foot doctor and he said nothing works on fungal infections in toenails because the infection is in the root of the nail.
