Transform nails to be long, strong, and resilient. Two coats of this strengthening treatment featuring innovative, multi-polymer technology create a shield-like barrier that immediately fortifies the nail plate and helps harden over time. Resilience is improved in as little as one week—with a noticeable increase in hardness—and with the infusion of our proprietary Florium Complex, nails get the perfect dose of the hydration and nutrients needed to support healthy nail growth.

  • Free of phthalates, parabens, silicones, and gluten
  • Vegan and cruelty-free

For best results use as a treatment: Apply 2 coats to bare nails every other day for the first 2 weeks. Get Strong Nail Hardener should be removed before applying a fresh coat of treatment. During week 3 and 4 apply 2 coats to bare nails every 4-5 days. Repeat process as needed. 

As a base coat: Apply one coat to clean nails and follow with your favorite lakur shade.

    This is the bomb! Just buy it!

    I never write reviews, but this nail hardener is really amazing. NOTHING has helped strengthen my nails before this. I tried every single product on the market. Spent hundreds of dollars trying to heal my nails after gel manicures. They were paper thin and would not grow. Within 2 weeks of using this product, along with the illuminating polish and base coat, top coat... I have nails again. They are strong and healthy. Regrowing healthy nails was something i almost gave up on until these products.

    8f you're on the fence... Just buy it! You will not regret it!

    Noticeably stronger.

    After using the treatment for 1.5 weeks, I can attest that they are stronger and appear healthier. The polish layers peel before reaching a full two weeks (as label instructions advise). Despite this, I like the polish and plan to purchase it again in the future.

    It’s working

    I’ve had fake nails for many years and decided to quit getting them. I started using your products, including the cuticle remover. In a short few weeks I can see an improvements and will keep using with the hopes of having healthy and beautiful nails.
