The short answer
What is dandruff, and when should I get help for it?
Dandruff is common scalp flaking that may itch and can appear as white or yellowish flakes. It is often associated with seborrheic dermatitis, which can also cause redness, irritation, or greasy scale on oily areas such as the scalp, eyebrows, ears, or face. Mild dandruff often improves with regular washing, but persistent or severe symptoms deserve medical assessment. Dandruff can recur even after it improves, so ongoing scalp care may be needed.
When might more than messages be needed?
A remote history and video may suggest dandruff, but they cannot always distinguish it from psoriasis, eczema, scalp ringworm, or another condition, especially when the scalp is hard to see. Arrange in-person evaluation when symptoms persist despite self-care, are severe, spread beyond the scalp, or involve marked redness, pain, crusting, drainage, or pus. Testing is sometimes needed.
