Ringworm on the scalp or nails – when to get help
Why scalp and nail ringworm needs a different level of care from a small skin patch, and when a South African clinic should assess it.
Scalp and nail infection needs professional assessment
Ringworm is a fungal infection of the superficial skin, hair or nails. A small skin patch may be managed differently from infection on the scalp or nails. NICD advises medical review when large areas, the scalp or nails are involved because prescription treatment or testing may be needed.
Look for the site, not only the shape
- Scalp involvement can cause scaling, broken hairs, tender areas or hair loss.
- Nail involvement can make a nail thickened, discoloured or crumbly.
- Skin ringworm may be itchy, scaly or ring-shaped, but other rashes can look similar.
- A rash that keeps spreading or fails to improve needs a diagnosis check.
Avoid sharing towels, hair tools, hats or bedding while a contagious fungal infection is possible, and wash items as advised by the healthcare team.
Get the treatment matched to the site
- Tell the clinician whether the scalp, nails, feet, groin or other areas are involved.
- Mention diabetes, HIV, immune treatment and previous antifungal use.
- Use treatment for the full course and site as prescribed.
- Return if it spreads, recurs or does not improve as expected.
A widespread or resistant rash needs care
Common questions
- Can ringworm affect the scalp or nails?

- When should I see a doctor for ringworm?
- Seek review for scalp or nail infection, a large or spreading area, a weakened immune system, severe inflammation or little improvement with appropriate treatment.
