can already tell a big difference!

I have only been using this a week and can already tell a big difference! I use it morning and after I shower at night, make sure to dry your nails really good and resist the temptation to wear polish!

I would recommend.

I had two toe nails that needed help. This stuff has done a great job so far. I noticed a change starting to happen pretty quickly. It appears to be getting the color back to normal. It doesn’t smell. Doesn’t stain. It’s easy to use. And it seems to work well. I would recommend.
