Sally Hansen Nail Strengthener Repair + Rescue Super Strength Defense (Amethyst) — Strengthens in 1 Week

Sally Hansen Repair + Rescue Super Strength Defense is a nail treatment that instantly fortifies and helps strengthen fragile nails, with clinical and consumer testing showing measurable improvement within one week.*

This skincare-inspired nail treatment from Sally Hansen builds a flexible, protective barrier on the nail surface to help reduce breakage and visibly improve nail appearance. Formulated with Amethyst, the formula is designed to make nails feel harder and stronger while maintaining a natural finish, so you can confidently go bare or use it as a base under polish.

How does this treatment work to strengthen weak nails?

The formula deposits a flexible layer across the nail that absorbs everyday stresses and helps prevent splitting and chipping. Clinical and consumer testing indicate the product delivers measurable strengthening after four applications within a single week, improving overall nail resilience.

• Amethyst-infused formula creates a flexible protective barrier
• Reduces immediate fragility for fewer snags and breaks
• Clinically and consumer tested; measurable strengthening after four uses in one week*

Can I wear it alone or under nail polish?

You can use Super Strength Defense on bare nails for a natural, reinforced look or apply it as a base coat beneath color. Its lightweight finish supports polish adhesion without adding heavy thickness, making it versatile for different routines.

• Use solo for a clean, strengthened natural nail appearance
• Applies smoothly as a base coat under regular nail polish
• Leaves a subtle sheen without looking like a thick overlay

When will I see results and how should I apply it?

Results are noticeable quickly as nails feel firmer after application, with instrumental testing showing strengthening after four uses in one week. For best results, apply to clean, dry nails and follow your usual polish or maintenance routine.

• Apply to clean nails; one thin coat is sufficient
• Use consistently—testing measured benefits after four uses in one week*
• Reapply as needed or use as a base coat before color

Is it safe for damaged or brittle nails?

Repair + Rescue Super Strength Defense is formulated to be kinder than heavy hardeners, offering flexible protection rather than rigid layering. It’s intended to improve the nail’s look and strength without over-brittleness, but if you have a specific nail condition consult a professional.

• Flexible barrier reduces risk of further chipping or splitting
• Skincare-inspired approach focuses on visual and structural improvement
• Clinically and consumer tested for visible enhancements in appearance

Who is this for: Sally Hansen Repair + Rescue Super Strength Defense suits anyone with fragile, easily chipped, or thin nails who wants a lightweight, skincare-style treatment to fortify nails quickly. It’s ideal for users who prefer a natural finish or need a reliable base coat under polish and want measurable improvement with consistent use.

*Instrumental measurements showed strengthening after four uses in one week. Individual results may vary.
