Quimica Alemana Nail Hardener/Esmalte Endurecedor para Unas .47 OZ

The best product for your nails ever.... It really works.

I’m so happy that I discovered this product! I have tried a thousand different products like this and nothing even comes close to working as well as this does! Someone commented that they only use this on the upper half of their nails, the tip, and not the bottom half towards the cuticle because it does have formaldehyde as one of the ingredients, so I have been following that advice. Not exactly happy about that ingredient but I haven’t had any bad side effects so it’s really not that big of a deal. I wouldn’t advise using if you have any broken skin around your fingernails, it tends to burn quite a bit, but honestly that’s the same as 99% of nail products. I haven’t experienced any burning otherwise. I wouldn’t consider these negatives because the strength it gives my nails is amazing and extremely worth it to me. It acts as sort of a temporary shield. My nails were extremely damaged and thin from using fake nails and this product saved them! I don’t really understand the negative reviews, I’m going to chalk it up to user error. xD. For people who are experienced and familiar with these types of nail products, or if you’re new but can carefully follow instructions, I *highly* recommend! I will definitely be purchasing again!

I wish I can say this is the cure to weak nails, but I know everyone is different. I have used this brand before and yes it does sting a bit, but I tend to push through it. When it's dry I leave it on till I need to reapply and ai do notice that my nails get stronger and grow without many cracks. I hope it helps others and it's a good fit for their nails. But doesn't hurt to give it a try.

I bought this to help my nails heal and get stronger after years of gel manicures. My thumb and index finger nails are naturally thicker and less affected by gel manicures. My other nails, however, tend to get paper thin after using gel and are generally my weaker/thinner nails overall regardless of using gel or not.After reading the instructions and reviews I proceeded with caution. I first tested it out on my thicker nails and had no issues at all. It went on smoothly, dried quickly, with no pain or burning sensation that I had read about in other reviews, and my nails felt stronger after the first use.Feeling confident, two days later, I decided to try it on my weaker/thinner nails. It seemed fine at first, but as the polish began to dry more and more I started feeling the burning and throbbing that I had read from other reviewers. After 20 minutes the burning sensation got worse and I grabbed my bottle of acetone and removed it. The burning feeling stopped within a few minutes after removal but my nail beds felt sore and bruised and still throbbed the next day. My thumbs and index fingers, still felt fine. The instructions warn about use if you have thin or damaged nails. TRUST the instructions and trust the process. I won’t be using it on my damaged thin nails again until they have more healing time from my years of gel manicures but I’m still giving the product 4 stars because if you’re using it following the directions for thin nails it works very well. My thumbs and index fingers are very happy but their immediate neighbors (middle finger, ring finger, and pinky finger) have all decided that middle finger is speaking for all three of them. Read the instructions and play by the rules and you’ll be fine.

After getting several manicures last year, my nails were over-filed and became extremely thin and sensitive. They were so weak that even simple tasks would cause discomfort, and they just wouldn’t grow. I decided to try this nail strengthener, and I’m so glad I did!Since I started using it, my nails have become much stronger, and they’re finally growing again. The sensitivity is gone, and they feel healthy and resilient. I highly recommend this product to anyone dealing with damaged or weakened nails. It truly made a difference for me!

Quimica Alemana Nail Hardener is a game-changer for weak nails! After using it consistently, I've noticed a significant improvement in strength and durability. The application is smooth, and it dries quickly. It also helps prevent breakage and peeling. Highly recommend for anyone looking to strengthen their nails!

I am an ex-nail biter. My nails have always grown in very thin and peel off in layers. I’ve never been able to resist messing with them because it’s so uncomfortable for your nails to peel and bend at the tips! Could never even wear nail polish because it would just peel off with my nails. Pictures are my nails before Química Alemana, after two months of weekly use with no product on them, and then a close up of my nails with just a layer of Química Alemana. Not only does this stuff work and is easy to use, but it’s very shiny and looks even better than a regular clear coat if you just want a simple manicure. Although you CAN wear nail polish over it. Here is how I use it:Once weekly, I apply a thin layer on the tips of my nails, about 1/3 into the middle of my nail bed. After that dries, I apply a second layer over the entire nail. You can use it more frequently if you want, but I’ve found once weekly works just fine for me.Do be careful not to over-file your nails before use and DO NOT put it on too soon after removing acrylics, press-on nails, or anything similar because that can cause burning. If you have any injuries around your nails (cuts, etc) that can burn too.I’ve been using this for years and it really is a good product. I tell everyone about it because I get a lot of compliments on my nails now, something nail-biting 5-year-old me never would have thought would happen! I’ve always been insecure about how my nails look and this has increased my confidence and femininity so much. And I can’t believe it’s so affordable!

I’ve put it on twice so not sure what to expect.. but I will say this it’s so strong smelling it burns your eyes , made mine water so bad ! I’ll keep using to see what happens but yikes the smell
