Itchy Scalp at Night: What to Know

At bedtime there are fewer distractions, so an existing itch may feel stronger. Heat from bedding, sweat, dry room air, or a recently used shampoo can add irritation. Dandruff and Seborrheic Dermatitis may cause flaking or greasy scale, while Scalp Psoriasis can produce thicker scale. Folliculitis tends to cause sore or itchy bumps. Head Lice may cause persistent scalp itching and visible nits or insects.

Keep the room and bedding comfortably cool, wash with a mild fragrance-free cleanser, and pat rather than scrub the scalp. Keep nails short and use a cool compress instead of vigorous scratching. Inspect the hair close to the scalp in good light. If lice are found, avoid sharing pillows, hats, or combs and ask a pharmacist about Head Lice Treatment. Do not layer multiple medicated products without advice; Medicated Shampoo Treatment should match the suspected cause.

Seek an appointment if night itching continues, affects sleep, or comes with bleeding from scratching, oozing, painful bumps, thick plaques, or hair loss. Urgent help is appropriate for swelling of the face or trouble breathing after a product.

Does the pattern fit Dandruff, Seborrheic Dermatitis, Scalp Psoriasis, Folliculitis, or Head Lice? Could a product or dry skin be contributing? What should I stop, and how should a treatment be applied?
