This is the best formula to use if your nails keep breaking because it has built-in conditioners in it. I've been using formula 3 for a few months and I'm really impressed at how healthy my nails are. I'm going to buy some for my mom now because she currently has the same problem I used to have. This is a great product and I recommend it to anyone who's nails constantly break.

I went for a month without this product and my nails were definitely in need of another treatment. This product strengthens nails and can be used under regular nail polish. The protein helps to bond nail layers together and prevents peeling or splitting of nails.
