Sally Hansen Diamond Strength Nail Hardener

The Sally Hansen Diamond Strength Hardener is a nail polish that hardens brittle nails and allows perfect looking nail make-up. The nail hardener is suitable for all nail types. The formula is enriched by titanium and micro-diamond particles and lastingly hardens the nails. Brittle nail layers are reliably sealed. At the same time, the product seals the nails and allows healthy nail growth.

As easy to apply as nail polish

The product is applied to natural nails. To do so, add a thin coat of the nail hardener to the nail and allow to dry. The Sally Hansen Diamond Strength Hardener also make a perfect base coat for nail make-up. When used regularly, the nails appear stronger and longer after only five days. Further breaking, chipping and cracking of the nails is prevented.
