Quimica Nail Hardner, Pack of 3

This stuff is a miracle in a bottle. My nails are hard and growing like weeds.

I've been using this product for over 10 years! It makes my nails super strong! At first it may hurt a bit s o beware if you have super thin and damaged nails due to gel, maybe use just an oil until your nails get a bit stronger. Use it once a week until your nails are strong enough and then you can mantain with a once a month application.

Excelente. En un mes verás los resultados

Great stuff

Best product that I have ever used on my nails. Yes. It smells chemical and probably isn't the most "clean" product in the world, but it works well. I never had a single problem with burning or pain from using it. If you have problems with using stronger products or you have sensitive skin, then this product is not for you. There is no need to buy something and write awful reviews about it when you know that you have issues with stronger chemicals to begin with. If you have very thin nails, don't use this product. If you have cracks in your nails or broken skin around your nails, don't use this product. All that being said, it is amazing. Trick is to always have it on your nails. They will grow because they are fortified by the product. I use it alone and under nail polish. It dries quickly, but don't apply too much at a time because it will clump up. Honestly, i am blown away at how well it works. I have never had long nails in my life. I have actually had to file them down. I am just floored. I will never go with it again. My nails are as strong now as when I wore an acrylic over them. Don't be scared by harsh reviews from others. Follow the directions and simply go slow if it bothers you. I will repeat again if you know you have sensitivities to certain products don't waste your money. Go with a more gentle product. Thanks, i just wantedcto give everyone a heads up after reading so many reviews. I am just a straight forward person!!

Excelente , endurece las uñas

I used this product and it burned my fingernails I had to remove it immediately. Five out of 10 of my fingers turned black and will probably fall off. It cannot be returned for refund and it’s not cheap. I’m very disappointed that no one warned me this could happen.

Multiple purchases of this stuff works great
