QUIMICA ALEMANA Nail Hardener (protective barrier prevents chipping, peeling and splitting) - Size 0.47 Fl.oz (Pack of 2)

I recently tried the Quimica Alemana Nail Hardener 7-pack, and I’m really impressed! The formula strengthens nails quickly, reducing breakage and peeling. After just a few uses, my nails feel noticeably harder and healthier. The 7-pack is a great value, especially if you like to keep a backup or share with friends. Easy to apply and dries nicely without leaving a sticky residue. Highly recommend for anyone looking to maintain strong, beautiful nails!

If you have trouble growing your nails this is the answer!!! If you use it as a base coat and then apply it once or twice during the week you will be amazed at the growth and strength of your nails!!!

This is the best nail hardener I have used.... my brittle nails are hard, strong & shiny... Chipping and peeling do not happen anymore....

I have been using this product on and off for a couple of years now. It really helps strengthen my nails and the more I use it I can feel a notice a big difference. Even after the first coat I can feel thaty nail is harder than before. It does sting a bit, but not enough where it is painful. At times, I would put two coats or just one and add a color nail polish on top. When growing my nails I try to be consistent and remove old polish and reapply a new coat every two weeks. But I used to bite my nails as a kid, and the fact that I can still grow them is a miracle and this product definitely helps give that extra strengthening.

Bought this on recommendation from a friend. The product seems to work, but caused medical nail issues for me. The nail hardener burns sometimes hours after applying, despite carefully applying and avoiding cuticles and skin. This only happened intermittently. When I removed it a week ago, some of my nails were red, then developed purple and red marks which worsened and became very painful. Sleeping at night was difficult because fingertips were throbbing. Saw my dermatologist who said I had blood and bruising underneath the nails which is a reaction and to never use this product again. She said this is very painful and pointed out white area on one nail where nail is separating from nail bed from the damage. This can lead to several types of infections and I was prescribed a topical antibiotic and told to avoid having my hands in water. The hardener contains several problematic ingredients (look them up!) Formaldehyde, for one, is carcinogenic! Please, do your homework before ordering or using such products. FYI, I haven’t used gel, acrylic, etc. in years, so not a contributing factor.

Tentative 5 star because I’ve only used this for a little over a week. My nails were very thin and lady at nail salon recommended this product. This actually hurt for the first 2-3 days. Felt like my fingers were burning. I can tell my nails are getting stronger now and it doesn’t hurt at all anymore. Doesn’t sound like high praise, but it is.

If you get the beige color do NOT use it will yellow your nails and make them peal. This white one is the BEST it hardens the nails and stops the pealing!!!!! Amazon needs to know this info!!!!!!!!!! I got some bad from Amazons EK Luxury Concept,Inc. that I have been trying to let them know is horrible and so damaged my nails and my daughters!

A Great investment for nails!! I read that guitar players use this for strong nails. TRUE! My nails are totally stronger & grow more. It actually amazes me. Ignore the cost..this is VALUE.

Splitting & chipping was a problem. After trying several products I came upon Quimica Nail Hardner. Never looking back. Gives everything needed to make your nails strong. Quickly came back to long, healthy, strong nails

Definitely works to strengthen nails so they can grow.

It is an excellent product as it helps strengthen nails and they grow very quickly.

Nail Hardener works wonders! My nails are stronger and healthier. Love it

This burned and damaged my nail beds horribly back in late March of this year. I nearly lost two nails on my left hand and my nails still look rough months later. The second picture was taken right before applying the product, and the first picture shows nearly four months of healing. I couldn't bear to take photos of what they looked like April through June, preferring to wear solid colours to cover them instead. You can still see the orange/brown areas where this product burned my nails, and the obvious difference in the bed length where the tissue was burned away. It took weeks for the pain to fade, and they're still sensitive during filing and shaping. I know I've still got months until they fully heal. An awful, embarrassing, and painful experience. I wish I'd never purchased this stuff.
