What should you know about patchy flaky scalp?

Fine white or greasy flakes with itch can occur with Dandruff or Seborrheic Dermatitis, often around the scalp and other oilier areas. Thick, sharply defined scale that extends beyond the hairline can fit Scalp Psoriasis. A round scaly patch with broken hairs, tenderness or hair loss may suggest Scalp Ringworm, which needs medical treatment rather than cosmetic care. New shampoo, hair dye, oils or tight hairstyles can also irritate the scalp. The appearance alone cannot confirm the cause, especially when several problems overlap.

Wash regularly with a gentle shampoo and avoid scratching, picking scale or applying strong home mixtures. If a pharmacist or clinician recommends Medicated Shampoo Treatment, follow the label or treatment plan and allow the product to contact the scalp for the instructed time. Pause a newly introduced dye or fragranced product if burning began after use. Do not share combs, brushes, hats or towels when infection is possible, and clean items that touch the scalp. Keep a note of itch, soreness, hair shedding and whether flakes return after washing.

Arrange a review if flaking persists despite appropriate shampoo use, spreads, forms thick plaques, or is accompanied by redness, pain, pus or marked itch. Seek prompt assessment for round patches with broken hairs, swollen glands, or new areas of hair loss because Scalp Ringworm can spread and may need prescription treatment. Seek urgent help for rapidly spreading redness, facial swelling, fever or severe pain.

Does this look more like Dandruff, Seborrheic Dermatitis, Scalp Psoriasis, infection or contact irritation? Do I need a scalp sample? Which shampoo should I use, how often, and for how long? What should I do if hair shedding or soreness appears?
