Fungal Scalp Infections
Scalp ringworm is a fungal infection that can cause scale, broken hairs, and patches of hair loss.
Despite the name, ringworm is not a worm. It can spread between people and sometimes from animals. Children are commonly affected, but adults can develop it too, and appearances vary.
Quick answer
Scalp ringworm is a fungal infection that can cause scale, broken hairs, and patches of hair loss. It usually needs prescription oral treatment; shampoo alone does not reliably eradicate infection in the hair shaft.
Symptoms can resemble other conditions
A scaly patch with broken hairs, black-dot hairs, or localised thinning can raise concern. Some infections produce a tender, swollen, boggy area called a kerion. A clinician may examine hairs or take a sample to confirm the cause.
Do not treat every flaky scalp as ringworm, but do not assume patchy scaling is ordinary dandruff either.
Get appropriate treatment
Because the fungus can involve the hair shaft, a prescribed oral antifungal is often required. The drug and duration depend on the clinical situation. A medicated shampoo may be added to reduce spread, but is not a substitute for the prescribed course.
Avoid using a steroid product on an undiagnosed patch unless advised. It can change the appearance and delay proper treatment.
Reduce spread and protect the scalp
Do not share combs, brushes, hats, or pillow items while infection is being assessed or treated. Follow the clinician’s instructions about cleaning items and whether close contacts or pets need evaluation.
Seek prompt care for painful swelling, pus, fever, or rapidly worsening patches because severe inflammation can threaten follicles. Do not squeeze a boggy lesion or try to drain it at home. Early evaluation is more useful than testing multiple over-the-counter oils.
Frequently asked questions
Can an anti-dandruff shampoo cure scalp ringworm by itself?
Usually not. Scalp infection commonly requires an oral prescription medicine. Shampoo may be an additional measure to reduce spread when a clinician recommends it.
