What Are Nail Diseases?

Nail diseases refer to a range of conditions that affect the fingernails or toenails, including changes in colour, thickness, shape, or texture.

They can be caused by:

While many nail conditions are not serious, some may require medical treatment — especially if they are persistent, painful, or spreading.

At Dermo Direct, Australian clinicians can assess nail concerns online and recommend appropriate next steps.

Common Nail Conditions

1. Fungal Nail Infection (Onychomycosis)

One of the most common nail conditions in Australia.

Symptoms:

  • Thickened nails
  • Yellow, white or brown discolouration
  • Brittle or crumbly edges
  • Nail lifting from the nail bed

Treatment:

  • Topical antifungals (mild cases)
  • Oral antifungal medication (moderate–severe cases, prescribed)

2. Ingrown Toenail

Occurs when the edge of the nail grows into the surrounding skin.

Symptoms:

  • Pain and tenderness
  • Redness and swelling
  • Possible infection (pus)

Treatment:

  • Proper nail trimming
  • Warm soaks
  • Medical procedures for severe or recurrent cases

3. Nail Psoriasis

A manifestation of psoriasis affecting the nails.

Symptoms:

  • Pitting (small dents in the nail)
  • Discolouration (“oil drop” appearance)
  • Thickening or crumbling
  • Nail lifting

Treatment:

  • Topical treatments
  • Systemic medications in more severe cases

4. Nail Trauma

Damage to the nail due to injury or repeated pressure.

Symptoms:

  • Bruising under the nail
  • Nail lifting or splitting
  • Pain or sensitivity

Treatment:

  • Often self-resolving
  • Medical care if severe or painful

5. Paronychia (Nail Fold Infection)

Infection of the skin around the nail.

Symptoms:

  • Redness and swelling
  • Pain around the nail
  • Pus (in bacterial infections)

Treatment:

  • Antiseptics or antibiotics (if bacterial)
  • Antifungal treatment (if chronic fungal cause)

What Do Healthy Nails Look Like?

Healthy nails are typically:

  • Smooth and even
  • Consistent in colour
  • Free from pits, grooves, or thickening

Changes in your nails can sometimes reflect underlying health issues, so it’s important not to ignore persistent abnormalities.

Causes of Nail Diseases

Common causes include:

  • Fungal infections (very common in toenails)
  • Repeated trauma (e.g. tight shoes, sports)
  • Skin conditions (psoriasis, dermatitis)
  • Frequent exposure to water or chemicals
  • Poor nail hygiene or damage from manicures

Risk Factors

You may be more prone to nail conditions if you:

  • Have diabetes or circulation issues
  • Are older (nails grow more slowly)
  • Frequently use nail salons or artificial nails
  • Wear tight or occlusive footwear
  • Have a weakened immune system

How Are Nail Conditions Diagnosed?

Diagnosis may involve:

  • Visual assessment
  • Review of symptoms and history
  • Nail clippings or scrapings (for suspected fungal infection)

With Dermo Direct, you can upload clear nail photos for clinician review — helping determine whether your condition is likely fungal, inflammatory, or trauma-related.
