What should you know about dandruff infection on scalp treatment?

Dandruff commonly causes itch and white or yellow scale without pus or marked tenderness. Seborrheic dermatitis can add redness and greasy scale. A fungal scalp infection or bacterial infection may produce broken hairs, tender bumps, thick crusts, drainage, swollen areas, or patchy hair loss. These findings need examination because the treatments differ.

Do not assume that every itchy or flaky scalp needs an antifungal medicine. A clinician may inspect the scalp, hair, and skin and decide whether testing is needed before selecting treatment.

For uncomplicated dandruff, a clinician may recommend medicated shampoo therapy, used according to its directions and applied to the scalp rather than just the hair. Persistent inflammation may need another topical treatment. Suspected fungal infection may require a prescribed antifungal plan, while bacterial infection may need different care.

Do not share combs, brushes, hats, towels, or pillow coverings while an infection is being considered. Wash reusable hair items and avoid scratching. Do not use leftover antibiotics, steroid creams, or someone else’s medicine.

Arrange a prompt scalp assessment for pus, painful bumps, thick crusting, broken hairs, patchy hair loss, swollen glands, or a rash that is spreading. Seek urgent care for fever, rapidly increasing swelling, severe pain, or feeling unwell. Children and people with reduced immune function should be assessed early when infection is suspected.

Ask whether the findings fit dandruff, seborrheic dermatitis, fungal infection, or bacterial infection; whether testing is needed; and how long to use the recommended treatment. Mention contact with affected household members, shared hair items, and any previous medicines.
