Quimica Alemana Nail Hardener 0.47 Fl Oz Pack of 2

This is the best nail hardener I have ever purchased. I always had an issue with my nails peeling, bending and breaking. I never had pretty nails. Since using this product my nails grow long and are very hard. I now have to clip/file them because they get so long. Excellent product - well worth the money. Order it you won't be sorry.

I love this nail polish that hardens your nails. My grandmother used to use it and it’s so fantastic. My nails are growing longer and stronger. This is a great quality nail polish hardener with formaldehyde. Thank you.

This is without a doubt the best nail polish on the market to harden nails and promote growth. I have been using it for a few years now. I have tried many other polishes but I don't want to have to use 5 different products when I do my nails. I have never experienced burning or discoloration of my nails. Of course nail polish is made of chemicals so there is always potential for individual reaction. This is true of anything. I have soft nails that bend. I use it as a base coat, 2 layers of color then as top coat. The next day my nails are harder than before. Sometimes I refresh with an additional coat in a week. My polish stays on longer, is glossier and chips less. I also use it alone. 2 coats then once a week I put an additional coat on. I do remove it every 3 weeks or so to let my nails breath overnight. I definitely notice a difference when I don't use it. If I have my nails done professionally, I take it with me to use but often the manicurist has it. Mine noticed the difference in just 2 weeks. She actually had to file my nails because they are getting a bit long. There is formaldehyde in it which is why it works so well but formaldehyde is nasty stuff no doubt about it. It is in many, many nail polish brands. Cost in the store is $9.99 or more/bottle but definitely cheaper on amazon especially with free s/h. I buy 2 bottles at a time. On the side, you can use less expensive color polish because once you apply the top coat, the color pops. Ok one last thing, as with other polishes, it does get gloppy towards the end of the bottle ~ 3/4 of the way down. I have read keeping it in the fridge makes it last longer. I have not done that...Hope this helps.

It works

I put this on my nails and within minutes my nail beds were on fire,the pain was so excruciating. My heart began to beat so fast and loud, I was dizzy and then the beeping in my ear was so loud. I was going to pass out! I was sweating perfusely and it hadn't dawned on me it was the polish. I thought I over filed them so I sprayed them with the blue spray they gave me after my pregnancy. It helped the smallest bit but I was still sweating and dizzy. I got some ice from the freezer put it on my neck and tried to just keep from passing out but it didn't help much. For 3 minutes I am scrambling to catch my breath and save myself from passing out. So I jumped in the shower fully clothed and ran cold water on my head and my neck. When the beeping stopped I got out the showers and realized the burning was coming back so I got acetone and cotton and took this poison off my nails! I finally started to feel normal a few minutes later, after fighting for my life for ten minutes. This shouldn't be allowed to be sold. I'm getting a refund but I don't think anyone else should have to suffer. Read all these reviews because I didn't and I could've died had I passed out and hit my head. I'm home alone. The makers need to be held accountable!

Este producto es increíble. Me habían comentado lo bueno que era, pero nunca ni tuve la necesidad, ni creía lo que decían. En fin, mis uñas comenzaron a volverse frágiles y por ende sin crecimiento y tomé vitaminas, ayude mejorando la alimentación, pero más sucedió hasta que una amiga me regaló hace tres meses mi primera Química Alemana y resultó milagroso para mis uñas. Se ven hermosas y largas por primera vez en 5 años. Úsalo confiadamente.

Burns at firsts but I trusted the process and healed my nails made the strong

I have ordered this product probably 6 times already. I already knew the product from before. It works in an excellent way. Just make sure to only use it once a week tops. But the last time, the liquid was a yellow color that is not normal

Por más de 6 años me puse uñas de acrílico constantemente, por lo que mis uñas estaban MALTRATADÍSIMAS. De verdad, eran como papelito, se me doblaban y rompían por todo. Nunca las pude crecer porque se rompían al instante. Intenté muchos esmaltes para recuperar mis uñas, ponerles cebolla, ajo, etc. Todos los remedios posibles, y mis uñas seguían igual. Pues me recomendaron este esmalte, que según era buenísimo para recuperar las uñas. Yo estaba escéptica, pero como quería cualquier solución posible, lo compré. Llevo usando este esmalte como 6-7 semanas, y estoy ENCANTADA. Jamás había podido crecer mis uñas lo suficiente como para que, si me las pinto, parezca que son uñas postizas. Lo que tienes que hacer es seguir las instrucciones que dice, aplicarlo cada semana y tener paciencia, porque hay que dejar que crezca toda la uña. La primera foto es de cuando lo empecé a usar, me gusta que parece que te pusieras esmalte transparente, deja las uñas brillantes. Las demás fotos son de cuando ya había funcionado el tratamiento. Ahora mis uñas, están súper largas y duras, en serio no me lo creo!!!! y sólo no están más largas porque me las rebajo con lima. Amo que cuando me pinto mis uñas parece manicura jajajjaa, súper recomendando!!!!

Never had such beautiful nails. It keeps my nails very hard. Only thing I don't like is that some nails are very sensitive for a few days after appling the polish. Strange

É ótimo. Caro, mas ótimo.

Demorou demais para chegar e não achei tão bom como costumo comprar

Compré este producto porque tengo las uñas extremadamente frágiles y porosas; ningún endurecedor me ha servido, por lo que decidí adquirir este producto que tardó en llegar. Sólo me lo he aplicado una vez y a diferencia de otros no se ha caído, sigue brillante y ha protegido mis uñas, por lo que espero que me ayude a fortalecerlas con más tiempo de uso.
