When should you see a doctor about itchy scalp?

Dandruff and Seborrheic Dermatitis can cause flakes with itch, often around oily scalp areas. Scalp Psoriasis may produce thicker, well-defined scale. Folliculitis can create tender bumps around hairs, while Head Lice may cause persistent itch and visible nits attached to hairs. A new hair product can irritate the scalp, and the correct treatment depends on the pattern rather than itch alone.

Stop any newly introduced fragranced product or dye and rinse the scalp thoroughly if irritation followed its use. Avoid scratching, picking scale, or sharing combs, brushes, hats, and towels. Use lukewarm water and keep nails short. Note flakes, bumps, sores, hair loss, exposure to an itchy person, and how the scalp responds to washing.

Arrange prompt care for spreading redness, warmth, pus, fever, marked swelling, severe pain, or rapidly developing sores. Book an appointment when itch continues despite gentle care, repeatedly disturbs sleep, causes bleeding from scratching, or occurs with patchy hair loss or broken hairs. A clinician can inspect the scalp and check for infection, inflammation, or infestation.

Ask whether the findings fit Dandruff, Seborrheic Dermatitis, Scalp Psoriasis, Folliculitis, or Head Lice. Discuss whether Head Lice Treatment or Medicated Shampoo Treatment is suitable, how to apply it, and when persistent symptoms should be reviewed again.
