I can't say enough when I say, "HOLY COW THIS IS AMAZING" I was in cosmetology school when I was given a bottle of this from my nail teacher. Years later life goes on and I had forgotten all about this bottle and was looking for a treatment for my toes when I remembered this bottle. For the life of me I couldn't remember the name but I did remember the shape of the bottle and the wonderful smell of it. So I looked and looked and when I found it on Amazon I about lost my mind with excitement! I've had on my right foot my pinky and middle toe nails were thick, yellow and brittle and couldn't tell you how it happened but they were ugly. Then one day I noticed white spots on my big toe! I've bought several bottles of this and use it religiously, several times a day! It's the only thing that's helping get rid of everything. It does take time but I'll never use any other product!
