Work better than other products and seen results

Works welll and quick results

very good product

This really works for me. I've been using it for years. I don't paint my nails, so I put this on first. The only thing is that after you get about a little bit more than halfway that in your nails, it creates a little bit a tiny bit of bubbles. It says almost that it's getting dried out. But I would highly recommend because it works

I use this one for more than 30 years, I am so happy, because came on time.

When using this product under regular nail polish, I don't need a new manicure for weeks. It keeps my nails growing long and not prone to breakage. It's great and worth the price,

I have been using Quimica Alemana Nail Hardener for about 2 years now and it's the only polish that works for me. It hardens my nails successfully where no other brand I've tried has worked. I highly recommend this product!

Only used for 1 week. Fingernails still continue to split %26 flake off sort of in layers, %26 make jagged edges. Have to try product longer to see better results.

‼️BEWARE‼️ ⚠️👎🙅‍♀️🚫❌️if I could give this product zero stars I would. This nail Hardener BURNED all of my nails and the bits of skin it got on. I had to remove it immediately with nail polish remover and soak my fingers in water. The pain lasted for hours. I guess it's different for everyone but I had a bad reaction to the chemicals and I never experienced this before from any other product. I wish I looked at the reviews beforehand because I saw others like mine. I would not recommend‼️☹️😡
