What should you know about ringworm treatment for human hair?

Scalp ringworm can cause itchy scaling, broken hairs, patches of hair loss, tenderness or swollen areas. It can resemble other scalp conditions, so a clinician may examine the scalp and take hair or skin material for testing.

A topical cream may help nearby skin but generally cannot treat fungus inside hair shafts. Oral antifungal medicine reaches the infection more effectively and is often combined with a medicated shampoo to reduce shedding of fungal material. Do not share combs, hats, pillows or towels.

Take the prescribed medicine for the full course and report side effects rather than stopping it independently. Use any medicated shampoo exactly as instructed; it helps reduce spread but is not a substitute for the prescribed oral medicine. Wash bedding, towels and hats, clean combs or replace them, and avoid sharing hair accessories.

Arrange assessment for close household contacts and pets if they develop scalp scaling, broken hairs, hair loss or an itchy rash. Gentle handling is preferable, and scratching can damage the scalp and introduce bacterial infection.

Seek prompt medical review for painful swelling, pus, fever, rapidly spreading hair loss, tender neck glands, or an area that becomes soft and boggy. Early treatment helps reduce inflammation and the risk of lasting scarring hair loss. Seek advice sooner for a child, pregnancy, liver disease, or medicines that may interact with antifungals.

Ask whether testing is needed, which oral antifungal fits your health history, how to use medicated shampoo, whether family members or pets need assessment, and when it is reasonable to return to shared activities.
