7 Common Causes of Nail Fungus (and How to Avoid Them)

Your guide to healthier, fungus-free nails – the natural way.

Nail fungus might not be the most glamorous topic, but it's a surprisingly common condition that can affect anyone — especially if you're always on the go or love a good salon manicure. Yellowing, thickening, brittleness — the signs of nail fungus are more than just cosmetic. If left untreated, they can worsen over time and become painful.

So, what causes nail fungus in the first place? And more importantly — how can you avoid it?

Let’s break down the 7 most common culprits behind nail fungal infections and how you can keep your nails clear, strong, and healthy.

Public Showers & Locker Rooms

Why it's a problem: Warm, damp environments are a playground for fungal organisms. Shared spaces like gym showers and poolside locker rooms are hotspots for picking up fungal infections.

How to avoid it: Always wear flip-flops or shower shoes in public areas. Avoid walking barefoot and dry your feet thoroughly before putting socks or shoes back on.

Wearing Tight or Non-Breathable Shoes

Why it's a problem: Lack of airflow around your feet causes sweat to build up, creating the perfect environment for fungi to thrive — especially in closed shoes worn all day.

How to avoid it: Opt for breathable shoes made from natural materials, change your socks daily, and give your feet time to “breathe” when possible.

Skipping Proper Nail Hygiene

Why it's a problem: Dirty nail tools, infrequent trimming, or neglecting the nail bed can increase your risk of infection — especially if you already have a small cut or hangnail.

How to avoid it: Keep your nails trimmed and clean. Always sanitize nail tools and avoid sharing clippers or files with others.

Nail Salons With Poor Sanitation

Why it's a problem: Reused tools, unclean foot baths, and improper sterilization can all lead to fungal transmission during pedicures or manicures.

How to avoid it: Choose reputable salons that use medical-grade sanitizers or bring your own tools to every appointment.

Injury or Trauma to the Nail

Why it's a problem: Even small cracks or trauma to the nail can create an entry point for fungi. Damaged nails are also more prone to peeling and discoloration.

How to avoid it: Be gentle with your nails. Avoid using them as tools, and protect them from hard impact. If you get a nail injury, keep the area clean and dry.

Wearing Nail Polish for Too Long

Why it's a problem: Constantly covered nails can trap moisture and prevent your nail from “breathing,” leading to fungus or discoloration under the polish.

How to avoid it: Take breaks between manicures to let your nails recover. Stick to breathable or non-toxic polish whenever possible.

Underlying Health Conditions

Why it's a problem: Conditions like diabetes, poor circulation, or a weakened immune system can make you more susceptible to infections, including nail fungus.

How to avoid it: Keep chronic health conditions managed with the help of a healthcare provider. Regularly inspect your nails for any changes in color or texture.
