I ordered this product based on a article published on the Internet that jojoba oil remedies "age related" nail cracking and flaking problems. When I started using this product a month ago, my nails top layer kept breaking off or cracking such that they would not grow beyond edge of my finger's nail bed. It was very frustrating because my nail edges were rough and would snag on my clothing and make it hard to do tasks that require fine finger movements like peeling the back off an adhesive label. Because of this problem, I needed to carry an emory board with me to keep smoothing the ragged edges.It has solved my nail problems. I intend to continue using this product on a daily basis.
