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.

    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.

    Split nail repairing

    So far so good using the Strong Nail Hardner. I put on top of my split nail and it is holding the split area together and down. Its not catching on things as usual, so far. Im happy with it. As far as making my nail stronger, only time will tell for sure. Ive only had this about a week. I will further review when more time has passed.
