I have been using this product for the past couple of weeks. My nails were not long and were in their usual thin and weak state. I started using this product alone without any nail polish to get my nails conditioned and to allow them some time for growth. I have reached the point where I can tell the product is working. I haven’t lost a nail since I began using the product. My nails are growing out evenly and are almost all one length. I can also say that my nails are not splitting like they used to.
