Nail fungus can cause thick, yellow, or brittle nails, especially in warm, moist environments like closed shoes or public pools. A simple home remedy — **white vinegar** — may help.

**“Fungus loves moisture,”** so always start with clean, dry hands or feet. Apply **pure white vinegar with a cotton swab** to the affected nails twice daily, focusing on edges and thick areas. Use fresh swabs each time and disinfect tools to avoid spreading the fungus.

Stay consistent for **at least 4–6 weeks**. “Consistency is key to success with natural remedies.” If the skin is irritated, dilute vinegar 1:1 with water.

Avoid nail polish, keep nails trimmed, and let them breathe. Change socks daily, wear breathable shoes, and **protect your feet in public spaces** like locker rooms or pools by wearing flip-flops.

A strong immune system also helps. Eat a balanced diet rich in vitamins and antioxidants.

**If there’s no improvement or the infection worsens**, consult a doctor. White vinegar works best for mild to moderate cases — severe infections may need medical treatment.

With care and patience, **you can fight nail fungus naturally at home.**
