Philip Kingsley flaky, itchy scalp: what to know

Fine white or yellowish flakes with itch often occur when scalp oil, skin-cell shedding, and inflammation interact. Dandruff and seborrheic dermatitis can affect the scalp without causing hair loss. Thick, sharply defined plaques may fit scalp psoriasis, while tender bumps around hairs can point towards folliculitis. Sudden intense itch, visible nits, or itching among household contacts raises the possibility of head lice. A new shampoo, styling product, dye, or fragranced treatment can also irritate the skin.

Pause recently introduced scalp products and wash gently with lukewarm water. Avoid scratching, picking scales, or sharing combs and hats. A pharmacist or clinician can help select a medicated shampoo when dandruff or seborrheic dermatitis is suspected; use it as directed and allow contact time before rinsing. Lice need a different assessment and treatment approach. If the scalp is very inflamed, painful, or not settling after consistent care, arrange a dermatology review.

Seek prompt medical advice for spreading redness, pus, marked tenderness, fever, swollen glands, broken skin that will not heal, or patchy hair loss. Arrange an appointment for persistent scaling, recurrent flares, or symptoms affecting sleep. A clinician can examine the scalp and distinguish a symptom from conditions such as dandruff, folliculitis, head lice, scalp psoriasis, or seborrheic dermatitis.

Could this be dandruff, seborrheic dermatitis, psoriasis, folliculitis, lice, or product irritation? Which shampoo or treatment suits my scalp, and how long should I try it? What changes would mean I need a follow-up examination?
