Quimica Alemana Nail Hardener 0.47 fl oz

I really liked this product, after a few months of use my nails feel much stronger and healthier. The nail polish gives it a shiny appearance, so I really like it.

If you have thin nails. This is your answer. Will see results in a few days

Me ha fortalecido mucho las uñas, después de haber tenido por mucho tiempo uñas acrílicas, con este producto las he recuperado.

I have thin nails that tend to break...so I bought this product that is designed to help. First, this stuff is very strong; it absolutely reeks, so do not use it in a small or enclosed space. The first application of this went fine. I just applied for the second time a couple hours ago and my fingers started to burn. Really burn...like they were on fire. You could see the skin of my fingers through the nails turning more and more red. It took me about 10 minutes to wonder if it could be the polish, bc when have you ever used a polish that made your finger tips burn like that...so I take the product off and wash my hands a couple times. It took about 10 more minutes but the pain and redness finally started to subside. I emailed the company, because they put a paper in the package and ask that you contact them first. I asked if this is something that has happened before and he response I got was crazy. Basically, yes, we know that this happens. The product is really too strong for thin and brittle nails. You should use OPI instead. (I cut out some fluff, but thats the sum of it) So, this product is not actually for brittle nails, bc apparently it will kill your nails and nail beds. Beware.

This stuff is amazing! I used to have such brittle nails that would peel and get caught on fabric. I was so frustrated until I tried this. I use this as a base coat. It goes on clear and dries quickly. I noticed a difference in just 2 weeks. My nails are strong and beautiful!

I have recommended this to several people. My nails went from brittle to strong. I took off 1 star because of the formaldehyde, odor and my newest bottle has a brush with uneven bristles.

Excelente producto, hace crecer tus uñas y las hace más resistentes, te aconsejo que solo te coloques una capa, alejada de la cutícula y nunca lo apliques despues de una manicura, si tienes un corte te arderá mucho, pruébalo en una uña y si no sientes ardor, úsalo en el resto.

I have used this for years, it keeps my nails long and strong. I have to cut them down and they typically do not break. Starting out use a strip down the middle of the nail only b/c is can ache in the beginning
