Easy to Use
  • Most users notice clearer new nail growth in 4–8 weeks with consistent daily use. Improvement starts at the nail base as healthy nail grows in. Missing applications can slow progress and allow fungus to return.

  • Apply directly to the nail and surrounding skin using the dropper. Cover the full nail, edges, and under the tip if possible. Use twice daily—morning and night—and let it dry fully before socks or shoes.

  • Undecylenic acid is an FDA-recognized antifungal active. At 25%, it’s maximum OTC strength and helps stop fungus from spreading while supporting healthy new nail growth. Stronger than many drugstore formulas.

  • Better Nail includes tea tree oil + 6 natural oils to help condition nails and surrounding skin. They reduce dryness, support the nail bed, and make daily antifungal treatment gentler during long-term use.

  • When used consistently. Customers report clearer new nail growth, less discoloration, and improved thickness over time. With 25% undecylenic acid + 6 natural oils, results are strongest with daily use
