Koh
Win the battle against weak, soft nails with a specialist and powerful KOH nail hardener!
To provide a suitable solution for weak, soft and cracking nails, KOH has developed a powerful, high-intensity hardening treatment that maintains the natural elasticity of the nail and optimally stimulates nail growth.

Instructions:
Apply one layer on the first day, followed by a second layer on the next day.
On the third day, remove both layers with KOH Purifying Polish Remover® and immediately apply a new layer.
Perform these actions in a course of 16 days.
If the nails are weakened again after a few months, the treatment can be resumed. The KOH Nail Hardener Cure is TSF resin free, which means the chance of an allergic reaction is small.

Tip:
* Protect your cuticles with KOH Nourishing Cuticle Brush®.
* Apply KOH Nail Hardener Cure to the nails before going to sleep. This allows the active ingredients to work undisturbed during the night.
* KOH Nail Hardener Cure is not suitable for use immediately after removal of artificial nails. In that case, we recommend first treating your nails with KOH Essential Nail Serum for 8 weeks.
