Loceryl liquid is like a nail varnish which is transparent but contains an anti-fungal. It comes like a kit, in a box with emery sticks, swabs and applicators. It is expensive (French import) although has a good reputation. You only need to put it on weekly. Every pharmacy I know, has never heard of it, but I get it from my dermatologist or from Dr Cherdpong the foot specialist. Loprox I find to be useless. It also turns the nail yellow. I have heard about vinegar, although the derm doctor says it is no good as a cure.
