Itchy scalp in pregnancy: first-trimester guidance

Pregnancy can change skin sensitivity, but scalp itch is not a diagnosis by itself. Flakes or greasy scale can occur with dandruff or seborrheic dermatitis; thick, well-defined scale may fit scalp psoriasis. Tiny bumps, tenderness, or pus around hairs can suggest folliculitis. Nits attached to hairs or itching among household contacts raises the possibility of head lice.

A new shampoo, fragrance, hair dye, oil, gel, or protective style can irritate the scalp. Scratching can break the skin and make inflammation or infection worse.

Pause newly introduced fragranced products and rinse the scalp thoroughly with lukewarm water. Wash gently with fingertips rather than scraping or picking, keep nails short, and avoid tight styles while the skin is sore. Do not start a medicated shampoo, lice product, steroid, or antifungal without checking its active ingredient and suitability in pregnancy.

If lice are possible, avoid sharing combs, brushes, hats, or pillows and arrange assessment rather than treating blindly. A clinician can distinguish lice from scale and choose pregnancy-appropriate care, including a suitable shampoo when needed.

Arrange medical advice promptly for spreading redness, warmth, swelling, crusting, pus, marked pain, fever, swollen neck glands, or sudden patchy hair loss. Seek urgent help for facial swelling, breathing difficulty, or a rapidly spreading rash. If the itch continues despite removing an irritant, book a review with your maternity clinician or dermatologist.

Ask which diagnosis best fits the scale or bumps, whether a specific shampoo is appropriate in the first trimester, how often to use it, and what to do if symptoms spread. Bring the product labels of shampoos, oils, dyes, or treatments used recently.
