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.

    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.

    Love it!

    My nails have always been fairly brittle. I've never had long, healthy nails before. Thank you!

    No Noticeable Difference

    I’ve been using this as directed for the past two weeks, reapplying this nail polish every two days. My nails are still thin and still breaking. These are my before and after photos.

    We appreciate your feedback, Elizabeth. Thank you for sharing your experience using Get Strong Nail Hardener for 2 weeks! You indeed are doing well.

    To get the most benefits from this wonderful product, you will initially go through a 4-week nail regimen.

    For best results use as a treatment:

    • Apply 2 coats to bare nails every other day for the first 2 weeks - meaning you will have to remove and re-apply the polish every 3 days for 2 weeks.
    • IMPORTANT: Get Strong Nail Hardener should be removed before applying a fresh coat of treatment.
    • During weeks 3 and 4 apply 2 coats to bare nails every 4-5 days (Remove and re-apply).
    • Repeat the process as needed.

    Please keep us posted on the progress on the 4th week!
