Dry itchy spot on scalp: what to know

Loose white or yellowish flakes across the scalp can fit Dandruff or Seborrheic Dermatitis. A thicker, clearly bordered plaque with scale may suggest Scalp Psoriasis. Small tender bumps around hairs can occur with Folliculitis. Head Lice can cause persistent itch and visible nits attached firmly to hairs near the scalp; scratching may create sores. A localised patch can also follow a new dye, styling product, hat, or adhesive. A photo and scalp examination are often more useful than guessing from itch alone.

Pause newly introduced hair products and rinse the scalp thoroughly with lukewarm water. Avoid picking scale or scratching lesions, and wash brushes, hats, and pillowcases regularly. If the pattern resembles ordinary flaking, a Medicated Shampoo Treatment may help when used exactly as directed, but stop if it causes burning or worsening redness. If you see nits or live insects, seek advice about Head Lice Treatment rather than relying on repeated shampooing or home remedies.

Arrange a dermatology assessment if the spot lasts, enlarges, bleeds, becomes painful, or causes hair loss. Seek prompt care for pus, spreading redness, fever, severe swelling, or a rapidly developing rash. Get advice soon if children or close contacts are itchy, or if you are unsure whether particles are flakes or nits. Treatment depends on the cause, and steroid or antifungal products are not interchangeable.

Does this look like Dandruff, Seborrheic Dermatitis, Scalp Psoriasis, Folliculitis, or Head Lice? Should I use a Medicated Shampoo Treatment? How can I tell whether a product or hair treatment is irritating the area?
