This is a great base coat! Makes my nails less fragile and keeps my polish from chipping as quickly. I also use a top coat, the Dries Instantly one.

I'd you have weak nails this here is a game changer I got it for my mom and her nails are finally not breaking like they used too

This is a great top coat. It makes my nails very strong. My nail polish lasted a lot longer than it normally does. I would recommend.

I really liked this clear coat. The only thing is that I'm rough on my nails, so I do wish it lasted longer. But I would still buy this again.

i have used this a few times and it is relatively inexpensive, found in and surprisingly enough seemed to work.

It's ok... helped a little and made nails look a little healthier, but wasn't as strong as the stuff I use to get from Sally's beauty.

I absolutely love Sally Hansen nail polish because it's cheap and it lasts long I would recommend to everyone that has nails this stuff is very good

I use this product every night. It helps my nails to be hard and protects it from breaking. It's one of my favourites. Highly recommend

Sally Hansen nail harder is something we buy often with 4 girls who love doing their nails all the time.love that it makes my nails shine.

Honestly, I didn't notice a difference. I didn't feel my nails were any harder and it was strong smelling
