Itchy Scalp at the Back of the Head: What to Know

Look at whether the back of the scalp is dry and flaky, greasy and scaly, bumpy, or marked by scratches. Dandruff and Seborrheic Dermatitis commonly produce visible scale. Scalp Psoriasis may extend beyond the hairline and form firm plaques. Folliculitis produces inflamed spots around individual hairs, sometimes with pus. Head Lice can cause itch and nits attached close to the hair roots. A new dye, oil, gel, helmet, or collar can cause contact irritation where it touches.

Stop any newly introduced scalp product and rinse thoroughly. Wash gently, avoid very hot water, and do not pick at crusts or bumps. Use a mirror or ask someone to inspect the back of the head under bright light. If nits or insects are present, avoid sharing hair tools and follow professional advice about Head Lice Treatment. Medicated Shampoo Treatment may help only when its active ingredient suits the scalp problem.

Book a dermatology review if the itch lasts, recurs, or is accompanied by painful swelling, drainage, thick scale, open sores, or thinning hair. Get urgent help for rapidly spreading redness, fever with a tender scalp, facial swelling, or breathing difficulty.

What does the pattern on the back of my scalp suggest? Is testing or a close examination needed? Which shampoo or leave-on product is suitable, and how can I prevent the area from becoming irritated again?
