Conclusion: I sit at a keyboard all day typing and I'm an intermittent nail biter - which means my nails aren't always in the best shape. I am very pleased with Nutra Nails Naturals Nail Strengthener because it has helped a bit. Honestly, my nails are still a bit rough, but I love the clean looking sheen of my nails after using the strengthener - it is like an automatic buff. It also works really well as a base coat under nail polish. I would definitely buy this again.
