How effective is medicated shampoo treatment for scalp ringworm?

Scalp ringworm, also called tinea capitis, affects the scalp and hair shafts. Shampoo washes away surface fungal material and may make transmission to close contacts less likely. The infection can remain inside or around hair roots, so a clinician commonly considers an oral antifungal when scalp ringworm is diagnosed. Improvement in scaling may occur before affected hairs look normal again.

Use the prescribed shampoo exactly as directed, allowing it to remain on the scalp for the stated contact time. Avoid sharing combs, hats, towels, pillows, or hair equipment, and wash items that touch the scalp. Household members may need assessment if they have itching, scaling, or broken hairs. Do not stop oral medicine early because the scalp looks clearer.

Arrange a medical assessment for patchy hair loss, tender swelling, pus, crusting, or a spreading scaly area. Prompt care matters when the scalp is painful, the person is unwell, or a child has rapidly worsening hair loss, because inflammation can damage follicles.

Ask whether shampoo is an add-on or whether an oral antifungal is needed, how long each product should be used, and whether family members or pets should be checked.
