Query: Don't know about this stuff

I have been using this product for about 3-4 weeks. My nails are thin and peel but also brittle and often snap off when bumped. I have 2 nails that have a split line in them. As soon as they grow out past the end of my finger, the split portion rips back down to nail line. So far I have not noticed any change. Almost all of my nails look like I keep them cut down to the quick. I am hoping that as they grow out this time they will be stronger and that I will eventually grow out the 2 nails with the split in them and resolve that problem. This is an ongoing problem and I am hoping that with time this product will work. At least it is reasonably priced so I can afford to wait and see if things improve.
