Renunail Nail Strengthener (30ml) is a superior nail treatment used to strengthen and protect natural nails. Formulated with Calcium, it rescues and repairs weak, damaged nails, eliminating peeling and flaking.

Replacing hydration lost through the use of harsh detergents, Renunail Strengthener produces stronger, healthier nails with just 28 days use.

Directions of use:

  • Apply 2 coats of Nail Strengthener on day 1, avoiding the cuticles.
  • Over the next 5 days, apply a further coat each day.
  • On day 7 remove all layers and repeat the entire process for 3 more weeks.
  • Wait 1-2 weeks before further use to allow nails to rest.
  • For optimum results, apply ReNuNail Nourishing Oil to nails and cuticles throughout the process to maintain hydration.
