Nail Hardener

The Nail Hardener is a transparent nail polish that protects nails from daily attack, thanks to its harder and less brittle film than a classic nail polish. It strengthens nails and encourages growth whilst giving a bright touch. This treatment is suitable for all nail types and particularly soft, fragile nails or nails that bend.

Active Ingredients:

  • Iron and Diamond Powder
  • Vitamine E


  • Ensure nails are completely clean and avoid oily products.
  • Shake the bottle well.
  • Apply a first coat of Nail Hardener to the nails: start by applying a strip down to the center of the nail, then to the left and right sides of the nail.
  • Wait at least 2 minutes before applying chosen Nail Color.
