Steel Nails Hardener with Keratin, Calcium and Garlic

Really works. I get my nails done occasionally and they weaken my nails so bad. I applied this nail polish like directed. Saw a difference and felt the difference instantly. Worth it if you have weak and brittle nails.

I’ve used countless nail hardeners/strengtheners and this is the first one that truly works. As someone who works with my hands, it’s so hard to keep my natural nails long but I was so sick of the toxic relationship with gel manicures. With this, my natural nails are strong and growing!

This product out performs any nail hardener out there. It lasts quite long and the only reason I need to re apply is when my nails grow. Worth the purchase

My nails always split or lost layers and were so weak before this. I just use it as a base coat before color and it helps so much, ive never been able to grow my nails this long in my life

I bought this back in May of 2026, and it is currently September of the same year. When I tell you my nails have hardened significantly!!!! I mean WOW, I bought this because it was recommended to me, and my nails were so so weak from continuous Gel X Nails, when my new hardened nail started growing out, you could quite literally feel the difference in thickness, for a while I was losing the length because it was my old brittle nail. But as soon as my strengthened nail was at the tip, i have never chipped my nail since. I work at a Pandora, which requires strong nails to open up the clasps of bracelets almost everyday. My nails are stronger than some of the other girls hard gel or acrylic nails. I cannot rave enough of this product, I’ve sent it to all my friends. I will also add, in tandem with using this regularly twice a week, I also take a collagen supplement every morning. I think the combo has significantly sped up my nail strengthening.

This polish really works. The first time in my life I've had 10 nails. I couldn't give it 5 stars because halfway through the bottles, the polish becomes gummy and hard to use. I'm on the third bottle and the polish that has coagulated is almost a whole bottle. I tried to submerge in hot water, but that didn't work very well.

Ok wow… this is no joke . i’ve always been a very huge nailbiter and picker. Over the last year I have gotten a lot better at that. this stuff makes your nails very strong and actually hard. I’ve whacked my hands on things and my nails have not cracked at all like how they used to in the past, without this product. My mom and I have been using it for over six months and we absolutely love it. I’ll come back in another four months with my review again.

Love, love, love, love, love this!!!! My nails are thin and constantly breaking. I went to the dermatologist and had asked her if there is anything she can recommend for my nails and she said to buff them and apply a good hardener. This is the BEST hardener I have ever used. For over a week I had the same two layers on and there wasn't any peeling of the polish at all. I don't have a dishwasher and I clean my hardwood floors by hand so my nails are constantly getting soaked and this is the only product that has stood up to the test, all others would maybe last two days if I was lucky. I did just remove last week's polish to start fresh but I'm sure it would have at least held up another week if I let them go.
