My nails have never truly been tough...breaking easily and very brittle. Since using Sally Hensen Nail Hardener though, I have been quite surprised at how quickly my nails have thickened and are much stronger now. I am a big fan!

healthy-looking nails and Stops Nails From Breaking

It's a great bargain! The nailpolish bottle itself isn't nice looking but the content is amazing! My nails chip and break really fast and I used to bite my nails which made them more brittle and weak and this nail treatment works!!! It's cheap!! I use it as a basecoat then i can easily put nailcolor on top. So it protects my nails all the time!! I put it on also without any nailpolish on top..it's great! I recommend it to everybody with weak nails!
