Itchy scalp but not dandruff: what else can cause it?

Look for clues beyond loose flakes. Burning after a new dye, oil, gel, or shampoo can suggest contact irritation. Red plaques with a silvery scale can occur with Scalp Psoriasis, while tender spots or small pustules around hairs may fit Folliculitis. Greasy scale can occur with Seborrheic Dermatitis, and scratching can create small sores that keep the itch going. Head Lice can cause persistent itching, especially around the ears and the nape; checking hair shafts in bright light is more useful than judging itch alone.

Pause recently introduced hair products and rinse the scalp thoroughly with lukewarm water. Use a gentle, fragrance-free cleanser, avoid picking, and wash combs, brushes, hats, and pillowcases if lice are a concern. Do not layer several medicated products at once; a clinician or pharmacist can help choose Medicated Shampoo Treatment based on the scalp findings. Take a clear photograph of any rash and note when the itching began, what touches the scalp, and whether anyone close to you is itchy.

Arrange a dermatology review if itching persists, interrupts sleep, causes hair loss, or does not improve after stopping a suspected irritant. Seek prompt care for spreading redness, warmth, pus, marked swelling, fever, or painful open areas. A clinician can distinguish a scalp symptom from the condition causing it and check for infection or lice when needed.

Could this be contact dermatitis, Folliculitis, Scalp Psoriasis, or Seborrheic Dermatitis? Should I use a medicated cleanser, and how often? What signs would mean I need an examination or treatment for Head Lice?
