Most nail colours focus only on the surface, leaving fragile nails to fend for themselves. Sally Hansen Diamond Strength Nail Colour is designed to do both: deliver long-wearing, high-shine colour while helping to reinforce weak, brittle nails against everyday knocks and chips.

This formula is powered by a diamond-strength complex that includes micro-diamond particles and hardening polymers. Together, they create a durable, flexible shield over the nail, helping to support thin, peeling or splitting nails while resisting chipping and surface damage from daily activities.

The texture applies as a smooth, fluid lacquer that self-levels for an even finish. Once dry, it sets to a glossy, high-shine surface that resists dulling and visible wear for up to 10 days when used as directed. Nails feel protected rather than rigid or overly thick.

The brush is shaped to hug the nail for controlled, streak-minimising application in very few strokes. The formula is designed for buildable coverage, so you can apply one coat for a lighter look or add a second for a more opaque, impact-resistant finish.

Diamond-strength complex forms a hard yet flexible shield that helps protect against chipping and breakage.Self-levelling suspension system reduces streaks and pooling for a smoother, more even surface.Gloss-lock polymers maintain shine and colour clarity throughout wear, even with frequent hand washing.Fast-drying film technology helps shorten waiting time between coats while maintaining adhesion.

For best results on very fragile nails, pair with a compatible Sally Hansen strengthening base coat and finish with a Sally Hansen top coat to further extend wear. Use alongside a nourishing cuticle oil in the same range to support overall nail condition between manicures.

Sally Hansen Diamond Strength Nail Colour delivers long-lasting shine, salon-level wear and reinforcing care in every coat.

-

• Step 1. Start with clean, dry nails, removing any old polish and wiping away oil or lotion.
• Step 2. File and shape nails, then gently push back cuticles for a neat nail plate.
• Step 3. Apply a thin layer of strengthening base coat if desired and let it dry completely.
• Step 4. Apply a thin first coat of Diamond Strength Nail Colour using three strokes: one down the centre, then each side.
• Step 5. Allow the first coat to dry, then apply a second thin coat for fuller coverage and enhanced chip resistance.
• Step 6. Seal with a compatible top coat, running the brush over the free edge to help minimise tip wear.

Pro Tips

• Roll the bottle between your palms instead of shaking to reduce air bubbles in the lacquer.
• Cap the free edge of each nail with colour and top coat to help defend against early chipping.
• Allow a few minutes of drying time between coats to improve adhesion and wear.
• Apply cuticle oil daily around the nail to maintain flexibility and reduce the risk of splitting.
