What should you know about itching scalp during pregnancy?

Pregnancy can make skin feel drier or more reactive, but an itchy scalp still has several possible explanations. A new shampoo, hair dye, fragrance, or styling product can trigger contact dermatitis. Atopic dermatitis or psoriasis may flare or become more noticeable, with redness and scale. A skin yeast infection or scabies is possible when there is marked irritation, crusting, or itching in other areas. Widespread itching without much of a rash deserves discussion with the maternity team, because pregnancy-related causes outside the scalp can also need assessment. Describe the timing, visible changes, and any new products.

Stop newly introduced hair products and avoid dyeing or chemical treatments until you have advice. Wash with lukewarm water and a mild, fragrance-free shampoo, then pat rather than rub the scalp. Keep nails short and avoid scratching or picking flakes. Do not start medicated shampoos, steroid products, antihistamines, essential oils, or oral medicines without checking with your obstetric clinician, midwife, pharmacist, or dermatologist. Bring the product name and ingredient list to the discussion so the safest option can be selected.

Contact your maternity or medical team for intense or widespread itching, itching that disrupts sleep, a new rash, yellowing of the skin or eyes, dark urine, pale stools, painful swelling, pus, fever, or rapidly spreading redness. Seek dermatology review for persistent scale, sores, crusts, or hair loss. Prompt assessment helps separate a scalp problem from pregnancy-related conditions that need different care.

Is this likely to be product irritation, eczema, psoriasis, infection, or a pregnancy-related cause? Which shampoo or medicine is suitable at this stage of pregnancy? Do I need examination or tests if the itch is widespread?
