I love this product! After getting pregnant with my son my nails go so brittle and thin. I seen Sally Hansen had just came out with this nail hardner so i decided to givr it a try. It is do easy to use its just like painting your nails. I could see a difference in my nails the very next day. I couldn' believe it, it was a miracle. I would recommend this to anyone who is constantly chipping their nails or have a hard time growing them out do to thin nails.

I don’t remember too much about this product. I do remember thinking what is the difference between this and clear nail polish? It did not do too much for me. No tricks to apply, just straight forward brush it on let it dry. It would probably work better for someone who has nicer nails to begin with. My nails have ridges and curl under if I let them grow out too long and this product doesn’t fix anything.

Ummmm what do I say... this nail polish did less for me than what I expected. I expected this to be the cure to my nails being weak and I guess that’s where I went wrong when I bought this that was the thought in mind. This nail polish is almost like a regular clear nail polish hardener you would buy anywhere top coat type of thing but it does have a little more firmness to it. I didn’t use it long enough to know if it helps your nails get stronger but it seemed like one of those things you would have to use all the time for the full effect

I do love this and I try to use it as often as possible. I love the shine it gives my nails and I do notice they thicken up just a tad. But this might be biased bc my nails are always extremely thin and break off way too easily. So I can't really blame it on this product for not doing its job. When I use it it's great. So I recommend.

This is my go to clear coat nail polish for when I don’t want to worry about chipped colors. It keeps my nails strong and prevents them from peeling off if they get too long. Even if they grow out, it’s not noticeable so it’s very low maintenance.

Definitely does the trick and doesn’t chip as much as some others I’ve used. I wouldn’t call it a nail strengthener really, it’s more like a hard coated shell around your nail that protects it. My nails are pretty week in general so they still break but if I keep up with putting this on it works pretty well.

I really notice a difference in my finger and toe nails after using this product. My nails have always been thin and brittle. With this polish my nails look and feel stronger. I have not broken a single nail since using this product, I would highly recommend to someone trying to grow their nails out.

You can’t go wrong with Sally Hansen products.. ESPECIALLY their nail strengthening products. I’m not really a polish girl so I use clear polish & this strengthening gel, and let me tell you.. if u have weak nails.. look no further. THIS is the product for u!! Give it a try & thank me later!!

I have horribly thin nails. In fact, the reason I do not have long nails is because they either split or break off. This seemed to offer some assistance but not quite the wonder-polish I was looking for. I will continue to try other products until I find the one that really works well.

I was unsure of this product before actually using! But, it did not fail me! Wanting to grow out my natural nails has always been a problem as they are very thin and crack easily! After following recommended usage, I was left with long, thick, salon ready nails! Saves me a ton on gel or acrylics!
