The unique ingredients guarantee harder, stronger nails within 16 days. The natural elasticity of the nail is maintained and the nail growth is intensively stimulated.

  • Contains beneficial ingredients that optimally stimulate and restart the hardening process of the nail
  • The natural balance of the nails is restored and the nail growth is stimulated
  • TSF resin free, reducing the risk of an allergic reaction

Important: The KOH NAIL HARDENER CURE is not suitable for use immediately after the removal of artificial nails. For repairing after the use of artificial nails we recommend the KOH ESSENTIAL NAIL SERUM.

TIP: Protect your cuticles with the KOH NOURISHING CUTICLE BRUSH. This rich emulsion contains high-quality ingredients and essential oils which ensures healthy and well-groomed cuticles.

HOW TO USE: Apply one coat the first day and a second layer the next day. On the third day, remove both layers with the KOH PURIFYING POLISH REMOVER and immediately apply another new layer. Repeat this process as part of a 16-day treatement. If the nails become weak again after six months, the treatment can be resumed. We recommend testing the KOH NAIL HARDENER CURE before use on one finger.
