Love having your toenails painted? You’re not alone. Nail polish adds a pop of color and hides imperfections. But have you ever wondered if it could cause toenail fungus? It’s a question worth asking, especially if you’ve noticed your nails looking yellow, brittle, or thick. Let’s learn about how nail polish causes fungus and separate fact from fiction.

Can Nail Polish Cause Toenail Fungus?
Yes, nail polish causes fungus. Nail polish creates a sealed layer over your nails. This seal creates the perfect environment for fungi to grow. Fungus thrives in warm, dark, and moist places, exactly what your nails become when covered in polish for too long. Here are the main risks:
- Once moisture gets trapped under the polish, it stays there.
- Dark nail polish blocks out light and creates an ideal environment for fungus to thrive.
- Some polishes contain harsh chemicals that weaken the nail’s protective barrier. Weaker nails are more vulnerable to infections.
- Using nail polish from salons or sharing it with friends can spread fungal infections.
So, while nail polish doesn’t directly cause fungus, it creates conditions that help fungus flourish. Read to learn more about toenail fungus treatment in Arizona.
What Should You Do if You Have Nail Fungus from Nail Polish?
Many people don’t realize that although nail polish causes fungus by trapping moisture under the nail, nail fungus is common and treatable. Here’s what you can do to tackle it:
- Your doctor might give you pills or a special cream to treat the fungus. Over-the-counter stuff can help.
- Fungi love moisture. Keep your nails clean and dry. After washing, dry your feet (or hands) well, especially between your toes!
- Trim your infected nails carefully. Cut them straight across, and file them down so the infection goes away faster.
- Disinfect any tools you use on your nails. That way, you don’t spread the fungus to your healthy nails.
- If your toenails are infected, wear shoes that let your feet breathe. Avoid tight shoes for keeping moisture.
- It’s tempting to cover it up with polish, but it can make things worse. Let your nails breathe while they heal.
- Some people swear by things like tea tree oil, but these aren’t always enough. It’s best to talk to your doctor before trying them.
- Even if your nail looks healed, keep an eye on it. Nail fungus can come back if you’re not careful.
Should You Go to the Nail Salon at All?
If your toenails aren’t healthy, applying nail polish causes fungus to spread more easily. Still, nail salons aren’t off-limits, but you need to be cautious. Here’s how to stay safe:
- Many fungal infections spread through shared tools. Bring your own clippers, files, and polish to minimize the risk.
- Look for salons that follow strict hygiene practices. Tools should be sterilized between clients.
- If you already have a fungal infection, avoid nail salons until it clears up. You don’t want to spread it to others.
Does Gel Nail Polish Cause Fungus?
Yes, gel polish can also increase your risk of toenail fungus. Gel polish stays on longer than regular polish, which means your nails remain covered for weeks. This coverage makes your nails more vulnerable to fungal growth. Old or expired nail polish causes fungus by carrying bacteria and fungal spores that worsen infections.
Removing gel polish can also damage your nails. The removal process often involves soaking in acetone and scraping, which can weaken the nail and create tiny cracks where fungi can enter.
If you love gel polish, make sure you:
- Take breaks between applications to let your nails breathe.
- Choose salons that follow strict hygiene practices.
- Avoid gel polish if you notice any signs of fungus.
How Long Can Fungus Live in Nail Polish?
Leaving nail polish on for too long creates a dark, moist environment, which is why nail polish causes fungus to grow. The survival duration of fungi varies:
- Fungal spores can persist for up to 1–2 years in unopened nail polish bottles under ideal conditions.
- Once exposed to air, fungi may survive for several months, though growth rates can decrease due to oxygen exposure.
- Fungi thrive in humid and warm conditions. Storing nail polish in such environments can promote fungal survival and growth.

Does Dark Nail Polish Cause Fungus?
Dark nail polish doesn’t directly cause fungus, but it can make things worse. Dark-colored nail polish causes fungus to thrive because it blocks light, which makes it the perfect breeding ground.
Fungi love dark, damp environments, so your nails become an ideal place for them to grow when covered in dark polish for too long. If you prefer darker shades, give your nails a break between applications. Let them breathe for a few days before reapplying polish.
Can Old Nail Polish Cause Fungus?
Yes, old nail polish can harbor fungal spores. Using old polish, especially if it’s been shared or used on infected nails, can spread the fungus to your healthy nails. Ignoring nail health and frequently applying nail polish causes fungus, especially if the polish isn’t removed regularly. Here’s a quick rule: If you can’t remember when you bought that bottle of polish, toss it. It’s better to be safe than sorry.
