Description
Sally Hansen Hard as Nails Nail Hardener transforms weak, brittle nails into strong, resilient nails that resist breaking and peeling. This clinically-proven formula contains nylon fibers and protein-building ingredients that penetrate deep into the nail plate to reinforce structure from within. The clear, protective coating can be worn alone for a natural look or as a strengthening base coat under polish. Regular use shows visible improvement in nail strength and flexibility within one week. The 0.45 oz bottle provides long-lasting value with Sally Hansen’s trusted wide brush for easy application. This hardener is particularly beneficial for those with naturally soft nails, frequent nail breakers, or nails damaged by acrylics or gel manicures. The gentle yet effective formula is suitable for daily use and won’t cause nails to become overly rigid or prone to snapping. Dermatologist-tested and recommended by nail professionals worldwide for achieving healthy, beautiful nails naturally.
Suggested Use
Apply to clean, dry nails as a base coat or alone for natural strengthening. Use daily for the first week, then 2-3 times weekly for maintenance. Allow each coat to dry completely before applying polish. For severely damaged nails, use twice daily until improvement is visible, then reduce frequency.
