QUESTIONS BEFORE YOU BUY
A few useful details before you begin. If you are pregnant, nursing, or diabetic, please check with your doctor before starting any antifungal regimen.
Customers describe yellowing starting to fade around weeks 3–4, with new clear growth at the base often noticed by weeks 6–8. Nails grow slowly, so consistency matters. Individual results vary; a full toenail can take longer to grow out.
One kit is designed for approximately 30 days when used twice daily on up to five affected nails. Follow the package instructions and choose the supply that fits your routine.
Apply NailScience first and let it fully absorb and dry before applying polish. A polish-free day each week can help you track progress. Always follow the product label.
Every kit is backed by our 90-day guarantee. Please review our current returns and refunds policy for eligibility and instructions, or contact support@trynailscience.com.

Follow the product label and consult a qualified healthcare professional if you have questions. If you are pregnant, nursing, diabetic, or have a medical condition, check with your doctor before starting. Stop use if irritation occurs.
