DEAR DR. GOTT:
I have been using decolorized iodine for my nails which have been splitting and shredding. It has worked wonders. When I went to get another bottle, the pharmacist was out and had to order it. In passing, she said she had highly recommended it to treat nail fungus. I have no idea how effective it is, since I never had a fungus problem. Perhaps this will help your readers.
DEAR READER:
I have seen a HUMCO brand of decolorized iodine that can be used for split and shredded nails. There probably are other brands available, but the regular bottle on pharmacy shelves is red and leaves a stain when applied to the skin. Because iodine is used as an antiseptic, it probably does work on nail fungus as your pharmacist suggested. Thanks for the tip.
