★★★☆☆
WORKED TEMPORARILY
I've tried Listerine, Vicks, Potassium Iodide, Oregano Oil, and pretty much every other common OTC "cure" including methylene blue topically and orally.
The only time my nails mostly healed I was drinking a gallon of milk a day and heavily supplementing zinc. This led to other problems such as IBS and lower libido so I stopped that regimen.
The other sensitive "cause" is once I start supplementing selenomethionine or even eating more Brazil nuts, the nails start getting more yellow and brittle.
Just looking for any other advice? Or does anyone have luck with internal pharmaceutical antifungals?
