  • Because Our Lives Are Not Nail-Friendly

    Unfortunately, nails face a steady stream of injustices that push them to the brink. Nails are often squeezed into tight shoes and stripped away at with harsh nail polishes. These effects weaken nails, making them more susceptible to chips, cracks and even infections.

I had a very hard time dealing with the smell of this oil. I know it has all kinds of healthy stuff in it, but it smelled too "funky" for me.

I purchased this with the hopes that it will work for my great toenails. I do keep my nails short because they are so thin & I really do see a slight improvement but it's only been a month with using this product. Fingers crossed my nails will improve
