Sally Hansen Diamond Strength Instant Nail Hardener, 0.45 Fl Oz, Pack of 2

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.

This stuff is fabulous !! I’ve never had long nails in my entire life and I am 50 years old. My nails have grown exponentially since I started using this product.. I cannot recommend highly enough.

Great stuff. Nails kept splitting and breaking. Now more

Really helped to give a smooth finish. Rated excellent on YUKA app. I have replaced all nail products for better items. I would give 5 stars but I have issues with the bottle. Solid surface means you can't see level of polish to dip. Shape of bottle not stable so has a tendency to tip. Like it enough to transfer to a clear more rounded bottle. A wider brush would also be helpful. My nails have improved so much the ridge splits are almost filed off.

Love this item. Keeps my nails from breaking and looks good!

Muy bueno para las uñas debiles

Not as hard as nails as described. The polish easily washes off during rehular hand washing. I'm disappointed with this purchase.

I stopped using Nail Envy (OPI) when they changed their formula and gave this a try. It’s a good base… doesn’t chip or lift so 5 stars!
