Fungal nail infections (onychomycosis) are one of the most common nail concerns we treat at Leading Edge Podiatry. They can be stubborn, unsightly, and frustrating for patients—especially if left untreated.

Below, our expert podiatrists answer the top 10 frequently asked questions we receive in our Blackwood clinic to help you understand this condition and the most effective treatments available.

1. What is a fungal nail infection?

A fungal nail infection occurs when microscopic fungi—most commonly dermatophytes—invade the nail bed, plate, or surrounding skin. Over time, this infection can cause the toenail to become discoloured, thickened, brittle, and uncomfortable or painful in enclosed footwear.

2. How do you get fungal nails?

Fungal nail infections are frequently contracted in warm, damp communal environments such as public swimming pools, gym locker rooms, and shared showers. Key risk factors include:

• Trauma or micro-damage to the nail plate
• Wearing tight, non-breathable footwear
• Spreading from an existing fungal skin infection such as tinea (athlete’s foot)
• Compromised immune system or reduced circulation

3. What do fungal nails look like?

Common signs and symptoms of toenail fungus include:

• Yellow, white, or brownish discolouration
• Thickened, distorted, or unusually brittle nails
• A crumbly or powdery texture underneath the nail plate
• Nails that lift or separate from the underlying nail bed (onycholysis)
• A distinct, unpleasant odour in advanced infections

4. Are fungal nails contagious?

Yes. Fungal nail infections can spread from person to person via shared surfaces (floors, showers) or contaminated items such as towels and nail clippers. Without prompt treatment, the fungus can also easily spread to neighbouring toenails or other areas of the skin.

5. Can I treat fungal nails at home?

While very mild superficial infections may occasionally respond to over-the-counter paints, most established fungal infections penetrate deep into the nail bed where topical remedies cannot easily reach. Home remedies rarely resolve the problem and often delay effective professional care.

6. What professional treatments are available?

At Leading Edge Podiatry, we offer a comprehensive range of evidence-based treatments tailored to the severity of your infection:

• Medical-Grade Topical Antifungal Lacquers: High-potency formulations designed to penetrate the nail barrier.
• Prescription Oral Antifungals: Our Senior Podiatrist, Jason Kuang, is an endorsed prescriber qualified to prescribe oral medications when clinically appropriate.
• Clinical Debridement: Professional thinning, trimming, and clearing of infected nail tissue to reduce discomfort and enhance treatment absorption.
• KeryFlex Nail Restoration: A safe, cosmetic resin application that instantly restores the natural appearance of damaged nails during recovery.
• Preventative Footwear & Hygiene Guidance: Targeted strategies to prevent recurrence and protect family members.

7. How long does it take to get rid of a fungal nail infection?

Because toenails grow slowly (approximately 1 to 2 millimetres per month), full clearance requires patience. It typically takes 6 to 12 months for a healthy, clear toenail to completely grow out. Consistency with your prescribed treatment plan is essential for long-term success.

8. Can fungal nails come back?

Yes, reinfection is common if the root environmental factors are not addressed. Ongoing management of athlete’s foot, wearing moisture-wicking socks, rotating breathable shoes, and attending regular podiatry check-ups greatly reduce the risk of reinfection.

9. Can I still get pedicures if I have a fungal nail?

We strongly recommend avoiding commercial nail salons while treating an active fungal nail infection. Salon equipment and footbaths can spread fungal spores to other clients, and applying standard nail polish can trap moisture and accelerate fungal growth.

10. When should I see a podiatrist?

You should book an assessment as soon as you notice discolouration, thickening, crumbling, or persistent foot itchiness. Early diagnosis and intervention prevent the infection from spreading across your toes and make treatment significantly faster and more effective.
