Fungal Nails: Common Misconceptions & What You Need to Know

Fungal nail infections (onychomycosis) are more common than you might think, yet they’re often misunderstood. Many people assume they’re just a cosmetic issue or that only poor hygiene causes them, but there’s much more to know. Let’s break down the facts vs. myths about fungal nails and how you can treat them effectively.

What Is a Fungal Nail Infection?

A fungal nail infection happens when fungus invades the nail bed, causing the nail to become:

✔ Thickened and brittle

✔ Discoloured (yellow, brown, or white patches)

✔ Crumbly or distorted in shape

✔ Lifted or detached from the nail bed

Fungal infections are stubborn and can take months to treat—but with the right approach, they can be managed and improved.

Common Misconceptions About Fungal Nails

❌ Myth #1: Only People with Poor Hygiene Get Fungal Nails

✅ Truth: Fungal infections have little to do with hygiene. They spread through warm, damp environments like shoes, public pools, and nail salons. Even the cleanest feet can develop a fungal infection if exposed to the right conditions.

❌ #2: Fungal Nails Will Go Away on Their Own

✅ Truth: Unfortunately, fungal nails won’t heal without treatment. In fact, they tend to worsen over time, spreading to other nails or even the skin (leading to athlete’s foot). Early treatment is key!

❌ Myth #3: Over-the-Counter Creams Work Instantly

✅ Truth: While antifungal creams and polishes can help, they take time and often work best when combined with professional treatment. Since the infection is inside the nail, topical treatments alone may not penetrate deep enough to fully clear it.

❌ Myth #4: If Your Nail Looks Healthy Again, the Fungus Is Gone

✅ Truth: Even if your nail starts looking better, the fungus may still be present under the surface. It’s important to continue treatment until a completely healthy nail has grown out.

❌ Myth #5: Only Older Adults Get Fungal Nails

✅ Truth: While aging increases the risk, fungal nail infections can affect anyone—especially those who wear sweaty shoes, go to public pools/gyms, or have conditions like diabetes or weakened immune systems.

How to Treat & Prevent Fungal Nail Infections

✔ Keep Feet Dry & Clean – Wash and dry your feet daily, especially between the toes.

✔ Choose Breathable Shoes & Socks – Avoid sweaty environments where fungus thrives.

✔ Disinfect Nail Tools & Shoes – Fungal spores can live in nail clippers, files, and footwear.

✔ Seek Professional Care – If your fungal nails aren’t improving, a foot care nurse can offer effective treatment options.
