I've had a nail fungus on my left thumb nail since 2010 and before as a result from working in a local school cafeteria. I had my hands in water all the time. I tried everything. My doctor even told me I would need an oral medication to get rid of the fungus, and my liver would have to be monitored because of the effects of the drug. Then, I was looking online for something, anything to help because I noticed one day out of the blue, it had spread to 4 toenails. The same toenails on both feet. I was getting desperate because it is the summer and I always wear nail polish on my toenails because I only wear sandals in the summer months. I didn't think it was very wise to wear nail polish on my toenails because I was afraid the polish would make the fungus worse. I found ORLY and ordered it. After the first week or 2 I started noticing a difference in the appearances of all my nails with the fungus! It was working!! I thought I would have to live with this fungus the rest of my life. I am so amazed at this product and would highly recommend it to anyone! Thank you ORLY for your product and for helping me to finally get this fungus out of my nails!! I'm so excited to be able to wear polish on my nails again soon. I was so impressed with the results that I bought a second bottle just to make sure the fungus is completely gone. I've only been using it maybe a month but I am seeing a tremendous change in my nails!!
