Can Scalp Psoriasis Cause Hair Loss?

Inflamed plaques can make the scalp itchy and tender. Scratching or lifting thick scale may pull out hairs that are already loose, and rubbing can break the hair shaft. These mechanisms differ from scarring hair loss, in which follicles are damaged and need careful assessment. Hair loss is not specific to psoriasis: tight hairstyles, chemical processing, infection, thyroid problems, nutritional issues, and other scalp conditions may also contribute. [Itchy Scalp](/symptoms/itchy-scalp/) and [Flaky Scalp](/symptoms/scalp-flaking/) can help describe accompanying symptoms.

Treat the inflammation as directed and soften scale rather than scraping it off. Use gentle handling, avoid vigorous brushing over plaques, and reduce tight styles, heat, and harsh chemicals while the scalp is sore. A clinician may recommend [Topical Corticosteroids](/treatments/medical-dermatology/topical-corticosteroids/) or [Medicated Shampoo Treatment](/treatments/medical-dermatology/medicated-shampoo-therapy/). Photographing the scalp and noting when shedding began can make changes easier to discuss.

Arrange an assessment for sudden, severe, patchy, or continuing hair loss, bald areas with smooth skin, broken hairs, scalp pain, pus, or bleeding. Seek prompt care for rapidly spreading redness, marked swelling, fever, or feeling unwell. A dermatologist can examine the follicles and decide whether psoriasis is the main contributor or another condition needs investigation.

Ask whether the loss looks like shedding, breakage, or follicle damage; how to loosen scale safely; and which hair practices should pause. Ask when improvement should be reviewed and whether another scalp or general health check is appropriate.
