Nail Infection Treatment: Diagnosis of Fungal Nail Infections & Other Nail Disorders
A clear guide to fungal nail infections and other common nail disorders, and the treatments that clear infection and restore healthy nail growth.
Treatment usually begins with
Nail Assessment
Fungal Testing
Antifungal Therapy
Nail Care Guidance
Treatment uses topical or oral antifungal medication depending on the extent of infection, alongside guidance on nail care to prevent recurrence.
You may need this evaluated if...
A dermatology evaluation is recommended when you notice:
- Thickened, discoloured or brittle nails
- A nail infection not improving with over-the-counter treatment
- Nail changes affecting multiple nails
- Pain or discomfort from an affected nail
Fungal nail infections and other nail disorders respond well to appropriately targeted treatment, though nail infections often need patience since nails grow slowly.
What is Fungal Nail Infections & Nail Disorders?
Fungal nail infections cause nails to become thickened, discoloured and brittle, and other nail disorders can have a range of causes, with accurate diagnosis important since treatment differs by cause.
Nails Grow Slowly
Because nails grow slowly, fungal nail treatment often needs to continue for several months to see full results.
Confirming Fungal Infection Matters
Not all nail changes are due to fungus, so testing helps confirm the cause before starting antifungal treatment.
Oral Treatment for More Extensive Cases
Topical treatment works for early, limited infection, while oral antifungal medication is often needed for more extensive nail involvement.
Prevention Reduces Recurrence
Nail and footwear hygiene significantly reduce the chance of the infection returning.
Common Symptoms
- Thickened nails
- Yellow, white or brown discoloration
- Brittle or crumbling nail edges
- Nail separating from the nail bed in some cases
What Increases Your Risk
A combination of genetic, environmental and lifestyle factors can increase the likelihood of this skin condition.
How It Is Diagnosed
A dermatological examination, often supported by targeted tests, confirms the diagnosis and guides treatment.
Clinical Nail Examination
A dermatologist assesses the pattern of nail changes.
Fungal Microscopy & Culture
Confirms the presence and type of fungal infection from a nail sample.
Assessment for Other Nail Conditions
Distinguishes fungal infection from other causes of nail changes, such as psoriasis.
Circulation Assessment (Select Cases)
Considered when reduced blood flow may be a contributing factor.
Treatment Approaches
Medical & Topical Management
- Topical antifungal nail lacquer for limited infection
- Oral antifungal medication for more extensive infection
- Nail care and footwear hygiene guidance
- Treatment of any other identified nail condition
Procedural & Dermato-Surgical Care
Nail removal is considered in select, severe or persistently resistant cases to allow more effective topical treatment underneath.
Treatment is tailored to your specific skin type, severity and how you respond, not a one-size-fits-all regimen.
Know When to Act
Recognising these signs early and seeking timely dermatology care helps prevent scarring and long-term skin damage.
Book an Assessment
Schedule a consultation for a routine evaluation or ongoing concern.
