Rock Hard Nail Hardener, One Color, 0.5 fl oz

This stuff works really well at hardening your nails and keeping them shiny. However, you need to keep up on re polishing them in order to keep them strong. If you wait and it all starts to chip off you will have a lot of breakage and need to start over again. If you are good about polishing regularly you will have nice strong nails. I just forget and seem to like this roller coaster I’m on. ;) You might also get frustrated with the brush, it doesn’t go all the way to the bottom of the jar. I saved my first jar. Once this second one gets down some I will transfer the remaining of the first into the second one.

The best nail strengthener.

I have horribly thin nails, due to nothing more than bad genes. They are so thin that my hair cuts through them in the shower! A friend suggested that I use this, and I'm glad I listened! I use this in conjunction with Rejuvacote for a week, then start over every 8 days, my nails are stronger, no more cracks/ tears at my pressure point in actually happy with my material nails now. Granted colored nail polish still chips of within hours but small price to pay. Keep in mind this is not an overnight miracle, it will take 3-6 months before you see results as long as you are consistent.

Excellent product! Lasts a few days. Doesn’t peel off too quickly. Have used Sally Hansen for decades, this is about as good.

Still doesn’t seem like it does anything to make nails stronger.

This is the one product I've found that provides daily protection against nails breaking and chipping. I have been using it for years. It provides a lovely sheen when used alone. The only caution is not to get it on too heavy, as that will cause it to yellow and chip.

Did not get make my nails strong or hard. I actually broke 2 nails by morning. Not a product I recommend.

Stays on my nails longer than any others! Most of the time I only use a clear topcoat on my natural nails. I am always” into something “, so colors are not practical for me. This really stays on, longer than any I have tried.
