Steel Nails Hardener with Keratin, Calcium and Garlic

This is the best hardener I’ve ever used. My nails are so strong and long. These are my natural nails, not acrylics

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.

This is the best nail hardener that has worked for my soft, thin, brittle nails. Use it twice a week and you will see your nails grow.

This stuff is amazing!! My nails have always been so brittle. After using this for a month or 2 my nails are very healthy and strong.

I like the polish, it works okay. It stays on for several days, but i don't feel like my nails are getting any thicker. They are growing much faster than usual though.

This is an excellent product. My nails are growing and they never grew like this before. I even quit going to the nail salon.

Was recommended by a co worker and I owe her lunch, it works amazing
