What should you know about greasy flakes on scalp?

Scalp oil can combine with shed skin cells, making flakes look yellowish or cling to the roots. Dandruff may stay limited to the scalp, while seborrheic dermatitis can also affect the hairline, eyebrows, ears, or facial creases and may cause redness. Product residue can resemble scale, but it often improves after gentle cleansing. Itching, soreness, crusting, or areas that do not wash away provide useful clues for a clinical examination.

Wash the scalp consistently with lukewarm water and a mild shampoo. Do not scrape the flakes or use harsh home remedies. A medicated shampoo can target dandruff and should be used according to its instructions, including any recommended contact time. Rinse well and avoid applying heavy styling products directly to the scalp. If the scalp remains inflamed, a clinician can decide whether a topical antifungal treatment or another option is appropriate.

Book an assessment if the flakes continue, recur quickly, or are accompanied by marked itch or redness. Prompt review is appropriate for pain, pus, spreading warmth, thick crusts, fever, or patchy hair loss. Do not keep changing treatments without advice when the scalp is raw or bleeding.

Do the flakes look like dandruff or seborrheic dermatitis? Which shampoo is suitable for my scalp? How long should I try it, and what changes would require an appointment?
