Scalp itching at night

Warm bedding, sweating, and reduced distraction can make an existing itch feel stronger at night. Dryness or eczema may cause tight, cracked, or rough skin; a new shampoo, dye, or pillow product can trigger contact dermatitis. Check for rash elsewhere, itching in household contacts, burrows, or small bumps. Scabies often affects several body sites and close contacts may itch too.

Keep the bedroom comfortably cool, use breathable bedding, and avoid fragranced products on the scalp. Keep nails short to limit skin damage. Wash new pillowcases and pause recently added hair products. Avoid sharing bedding, towels, or clothing if an infestation is possible.

Arrange a review when itching repeatedly interrupts sleep, spreads beyond the scalp, or comes with rash, scale, hair loss, or sores. Seek urgent help for facial swelling, trouble breathing, widespread blistering, or signs of infection such as fever and increasing redness.

Could this be eczema, contact dermatitis, psoriasis, or an infestation? Should household contacts be checked? What can I use safely at night without worsening the scalp?
