I definitely could see a difference in when I didn't use this hardener vs when I started using it a few weeks again.

This stuff literally makes my nails hard as rocks! Lasts for up to a week and a half if your not using your hands and working hard. I highly recommend this polish if your looking to toughen up your nails.

This is always my saving grace when I have times of weak nails. Sometimes I even use it as a base and a top coat when coloring my nails. I have used this for years and will continue to do so. For sure a great buy

I've used this before and I like it. It does help with brittle nails. The price is also decent

This did not work as well as I had hoped it would. My nails were were weak after having gel on for so long. It did help some but not much! :(

And I have to strengthen up my nails because they're a bit riddle this does the trick and make

I love Sally Hansen nail products. I've tried many of them. I think this is an absolute necessity for anyone who does their own nails. My nails tend to peel and split and this keeps them healthy and intact. Budget friendly and so easy to apply. I always have this in my nail box.

Takes a little longer to see results but if you use it long enough there are results.

This treatment is the holy grail of nail strengtheners! It really protects the nail preventing it from peeling or breaking so they can grow long and strong. The price can't be beat either.

I liked it because it delivered hard nails. They also grew pretty fast. Ive used it several times and the price isn't bad either.it does chip which I hate. Im not sure if that's because I should spend more money on hardeners to get better quality or if al hardners do that. Haven't bought it in years but I did like it
