I've had ugly tonail fungus since I was a child. I used regular nail polish which made it worse. So for years I used nothing and didn't wear sandles. Or, if I did, I tried to hide my toes. This past summer, I came across Drs. Remedy nail polish. Expensive but I tried the turquoise. OMG! I couldn't believe it. It covered like magic, is long lasting, and I couldn't stop looking at my toes. After a few weeks, when I took it off, my nails looked healthier than ever. I bought 2 more colors and now I'm getting the base coat.
