super nail European Secrets Rock Hard Hardener & Basecoat

It’s definitely working and I’ve only used it 2 times.

It truly strengthens and nails grow fast, much harder. I love this stuff!!! Worth buying.

I have used this product for sometime now, and I like it, it has a good full brush, better than most, its a good top coat and nail strengthener also. It seems to take a while to receive it for some reason, but its worth the wait, I guess, cause I always do.

I don’t know what is in this product but after one coat or two my nails are rock hard. It doesn’t strengthen your nails, who has time for that process? No this hardens as it dries allowing my thin weak nails to feel very hard. I’m a repeat buyer and I’ll stick up on this product!

I have been using this product for YEARS! I've told others about it. Here's what I do...I add vitamin E oil to my nails and let it soak in (usually overnight). DO NOT WASH OFF. Then I apply two thin coats of rock hard. After about 10-15 minutes, I add a coat of polish and a second coat 5 min later. Then I top it all with two coats of Out the Door top coat. Never chips!

Not sure why this was watery. I purchase this from the sally's in a different strengths and it works well hardening my nails. I will never purchase again. I am very disappointed. Amazon makes you give a star that isn't deserved on this purchase.

Does not get hard as you would want. Feels like a plain ol top coat

I've had thin crappy nails forever, they were so thin that my hair would cut through them in the shower, I got acrylic nails to avoid that but got tired of the cost. Nothing i have tried worked, so if go back to acrylics. Then I found Rock Hard....i can't believe the change, they are still thin but long and don't bend like they used to. I put on 2 coats of Rock Hard and one coat of rejovenate (sp?) As directed, then use Hard as Hoof to moisturize my cuticles. Took about 4 months to see the change! SOOOO WORTH THE MONEY!
