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.

    Works great!

    My nails had started being dry and breaking easily so I ordered this after reading reviews. I’m just finishing my 3rd week and my nails have successfully grown out like they used to. Easy to apply with wider brush applicator and drys quickly.

    It's very helpful .

    My nails are very weak. so I pick it to make nail hardner. I tried it a few time before I use lakur I put it at first to protect my nails. It worked very well.

    One more review singing the praises

    I wore acrylics for decades (yes, I AM that old), then wore gels for a few months. Finally wanted to just have bare nails and quit applying those nasty chemicals that were clearly destroying my nails. I’ve now been using this product and all Londontown products for over a year. I will say that this is my go-to base coat. I frequently use this base then follow it with the gel-like base. My nails are now rock hard. They had become thin, fragile, and horribly discolored. It has taken a while to let the discoloring grow out, but I can’t say enough good about this base coat and all the LT products. I confess, I did step away from the Lakur colors for a while and yep, the discoloring started to come back. So I’m sticking to what works. I’m a junkie for metallic colors, so LondonTown, if you’re listening, please make me a metallic true red. Think metallic Ferrari!
