Can scalp psoriasis cause hair loss?

Psoriasis affects the skin of the scalp, not usually the hair shaft itself. Thick scale can catch on hair, while scratching can loosen hairs or injure the surface. Active inflammation and soreness may increase shedding. Hair often grows back when the scalp settles, but a bald patch, scarring, or persistent thinning needs a closer look.

Hair loss has many possible explanations. Pattern hair loss, alopecia areata, scalp ringworm, traction, and telogen effluvium can present differently. A clinician may inspect the scalp, ask about timing and hairstyles, and check whether the loss is diffuse or in distinct patches.

Treat the scalp condition as directed and avoid picking plaques. Loosen scale gently after it has been softened; do not scrape or pull attached hairs. Choose loose hairstyles and pause harsh chemical or heat treatments while the scalp is tender. Take note of when shedding began and whether it follows a flare. For background reading, see [Hair Loss](/symptoms/hair-loss/) and [Alopecia Areata](/conditions/alopecia-areata/).

Book an assessment for sudden clumps of shedding, a smooth bald patch, scalp pain, pus, broken hairs, or areas that look shiny or scarred. Prompt review is useful when loss continues after the skin improves, since another cause may be present and may need different treatment.

Ask whether the pattern fits psoriasis-related shedding, how to remove scale without pulling hair, whether another scalp condition should be checked, and how progress will be monitored.
