Steel Nails Hardener with Keratin, Calcium and Garlic

I've been using Steel Nails (blue cap formula) for just over three months, and I’m pleased to share that my nails feel noticeably harder and less prone to peeling. This formula has become a staple in my nail care routine, but as with many intensive treatments, it’s not without nuance.It’s worth noting that some users report a burning sensation upon application. While I haven’t personally experienced this, I understand how discomfort can be disheartening. For those with sensitive nail beds or thin or damaged nails—especially after gel or acrylic removal—a gentler alternative such as the green cap formula or Essie Treat Love & Color might be a better fit.As for performance, I’ve found that two thin coats provide the best results. When I experimented with thicker coats or applied three layers, the polish was more prone to peeling. Several reviews mention peeling, and I suspect this might be due to overapplication. As with most strengthening treatments, less is often more.I've also used Steel Nails successfully as both a base and top coat, with no issues. It layers nicely under sheer or cream polishes and adds a subtle, protective gloss.A gentle reminder: while this product strengthens nails, it isn’t a license to misuse them. One reviewer was disappointed it didn’t allow her to scrape off stickers—but no nail polish can make your nails into tools. Even strengthened nails require care and respect to thrive.In short, this is a solid, results-driven formula for those seeking to fortify soft or weak nails. With thoughtful application and realistic expectations, it can be a valuable part of a nurturing nail care routine.

Finally something that helps my brittle nails. Quick results - awesome product

This stuff is AWESOME! I have unusually crazy thin nails - and they curl upwards as they grow. Lol, they are SO BAD they when I have gotten tired of them ripping all the time and get fake ones, the salon ladies have a field day with me, giggling that they can flex and bend my nails like paper.I can't not believe how strong my nails are with this stuff! They don't curl up and back, like they would normally, and they are no longer flexible and bendy. I AM SOLD!

Wow…I have purchased so many different nail hardeners, I can’t begin to count the bottles. Steel Nails really works! My manicure/polish has lasted for a week and my nails have remained strong, unbroken and unchipped.

Not sure if it really works but it’s a good base coat

Has helped my splitting nails. Awesome product at a great price

It doesn't do much, my nails are super weak

Best ever like steel nails three coats do a stellar job.
