Spotlight on | The Cure Nail Hardener
Despite our best nailcare efforts, there are times in the season or year when nails begin to look and feel weak, brittle and flaky. Indeed, a whole host of factors can take their toll on your tips – some we can control, others less so: the drying heat of summer, harsh winter weather, overexposure to water from regular swimming, dietary change and the aftermath of acrylic or gel nails.

For such nail health nightmares, you need repair, resilience and protection… you need a cure. And we have just the thing.

“Look to Nailberry’s aptly titled The Cure Nail Hardener. It more than lives up to its name.”

The Telegraph Online


We formulated The Cure Nail Hardener with these precise requirements in mind, researching, testing and selecting some of the most effective natural actives and combining them in a patented formula to deliver outstanding nailcare performance and protection. What’s more, in line with our ethos across all our range, this strengthening nail treatment is breathable, moisture permeable, vegan and cruelty-free – as well free from Phthalates, alcohol, parabens and Formaldehyde (to name a few).

“I came across The Cure after Googling repair remedies for damaged nails after consistent Shellac manicures. After just a few treatments, my nails felt stronger and less likely to split and crack. Now, a few weeks later, my nails are totally restored to a really healthy length. Wonderful wonder-product!”
Skye, Nailberry customer


The actives behind the action

The Cure brings together a unique blend of natural active ingredients to help repair, restore and harden weak, brittle nails. We use protein- and mineral-rich Black Algae for its renowned reparative qualities, antioxidant Acai Berry Extract for its protective benefits and a complex of Vitamins A, B5, C, E and F to help boost hydration and resilience.

“The Cure Nail Hardener - awarded Best for splitting nails.”

Candis Magazine


Proven performance

To be sure we’d got the formula right, we tested The Cure for three weeks with consumers experiencing brittle and broken nails. Here’s what we found:

  • Over 90% of testers agreed nail condition had improved
  • Over 90% of testers agreed nail brittleness and breakage had decreased
  • Over 70% of testers agreed their nails now split less
  • 100% of testers agreed nail shine had improved


“I have weak nails that persist in flaking and splitting. A combination of this nail strengthener and Acai Nail Elixir seem to be helping a lot. Well done Nailberry!” Jacqueline, Nailberry customer

As an intensely reparative nail treat, we recommend applying two coats of The Cure to clean, bare nails twice a week. You can also use The Cure as a breathable base coat under our L’Oxygéné nail polish – simply sweep on one thin coat and allow to dry before following with your chosen colour.

How is The Cure different to Acai Nail Elixir?

For those of you perhaps debating which nail treatment is right for your needs, our experts recommend you focus on your main nailcare concerns. For nails that feel particularly weak and brittle, The Cure’s specialist formulation actively helps strengthen. Dry, damaged nails that struggle to grow will instead benefit most from the multiple qualities of Acai Nail Elixir to help regenerate while boosting growth.
