Hair Psoriasis: What to Know

Psoriasis presents with inflamed areas and scale that may extend beyond the hairline. A person with scalp psoriasis may notice itch, dryness, redness, peeling, or thick adherent scale. Scratching and picking can break the skin and loosen hairs temporarily through physical trauma. Hair care products may sting when the skin barrier is cracked.

Dandruff, eczema, contact irritation, and infection can look similar, so appearance alone cannot confirm the cause. Symptoms can vary across the scalp and may change over time. See [Psoriasis](/conditions/psoriasis/) for information about the wider condition.

Follow the treatment schedule provided by your clinician and allow prescribed products to contact the scalp as directed. Wash gently with lukewarm water, massage with finger pads, and avoid lifting plaques with nails or comb teeth. Condition the hair lengths to reduce tangling, then pat dry. During active inflammation, limit bleaching, straightening, tight styles, and high heat.

Choose products that do not leave the scalp burning or increasingly itchy. If the scalp is [Dry Skin](/symptoms/dry-skin/) or [Peeling Skin](/symptoms/skin-peeling/), moisturising and scale care may be part of the plan, but thick plaques may need medical treatment rather than extra shampoo.

Arrange review when plaques persist, cross the hairline, bleed after scratching, or disturb sleep. Seek prompt advice for pus, spreading warmth, marked swelling, fever, severe pain, or sudden patchy hair loss. These signs can indicate infection or another diagnosis requiring examination.

Ask how to separate shampoo days from medicated treatment days, how to soften scale safely, and which styling services to postpone. Ask whether your symptoms fit psoriasis or another scalp condition and what change should trigger an earlier review.
