Nail Hardener 0.47oz 'Pack of 2' Body Care/Beauty Care/Bodycare/BeautyCare c

This chemical formula is strong. I feel it on my nails as I put it on and hurts a little but I'll deal with it to have stronger nails. Don't know if it's safe but that's the price one pays for long strong nails, right? Anyways, pain dissipates after 10 seconds or so. I have found that if I reapply every couple of days, my nails do actually start to grow after a couple of days. It is the only formula that has worked for me. Nails grow past a quarter inch and they are VERY strong and don't break easy.

This this product does not work like the old product did I wanted the old product the polished did not stay on and it was not a harder

It works

They changed the formula. The color is yellow brown and after a day my beautiful nails starting breaking. I really hope they bring back the original formula.

... but not for me. Perhaps I was not careful enough in applying and got some overspill on my skin past the tip of the nail. In a few moments, there was intense cold on several fingers and then intense heat. I concluded that I was allergic to some chemical in the product, and hastily removed as much of it as I could. Will not re-apply. Too bad - I bought a 2-bottle set.

This hardener was very painful on my nails, very intense pain. All ten fingers were hurting, this stuff is not good people don't buy this product. I bought it from my nail salon and I have to let them know this
