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. The KOH NAIL HARDENER CURE also comes in a luxurious case, which means you can take the bottle with you anywhere easily in a bag or suitcase. The case closes perfectly which makes it useful for use when traveling for carrying loose change, vitamin pills or jewelery.

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 course. 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.
