Instantly penetrating and quickly hardening the nail, Mavala Scientifique K+ Nail Hardener transforms soft, weak or splitting nails into strong, healthy tips. Infused with Pro Keratin, its strengthening formula hardens the nail plate so that the nail can restore its normal growth.

The tip of the nail is fragile and breaks easily, which means it’s the part of the nail that needs to be strengthened to leave you with incredibly tough, healthy nails.

On clean nails, apply from the centre of the nail to the tip only.  Use once a week until nails have reached the desired strength.

Please note: Never apply under nail, on cuticles, or skin to avoid hardening of the epidermis. If any product runs on to the skin, wipe it off with a damp cotton pad.
