Very good to strengthen nails
Great product.I have used this before and it makes your nails much stronger.I used to bite my nails for years and now I don't anymore.But this product makes my ugly nails look better and cooler. Any Sally Hansen nail product is a sure winner! Your nails also look shiny after you apply this so they look classier too.

Sturdy, Strengthening Nail Hardener That Works
I’ve been using Sally Hansen Diamond Strength Nail Hardener (0.45 fl oz) for a few weeks, and it’s quickly become a staple in my nail kit. The clear coat goes on smoothly and dries to a glossy finish—my nails look polished and healthy even before applying color. After every use, my nails have felt noticeably stronger and more resilient. What really stands out is how it helps prevent splitting and peeling. I work with my hands often, and since starting this treatment, my nails rarely show wear or damage. A small bottle lasts a long time, and it’s easy to add between manicures or wear alone. For anyone battling weak, brittle nails, this hardener delivers noticeable strength without being stiff or thick.
