Scalp Psoriasis: Symptoms, Hair Loss, and Treatment

Scalp psoriasis is an immune-mediated disease that causes well-defined areas of inflammation and scale. It can look like severe dandruff, but treatment may require prescription medication. Scratching and forceful scale removal can break hair and increase temporary shedding.

Psoriasis does not usually destroy follicles, so hair often regrows when inflammation and scratching are controlled. Scarring or persistent loss needs evaluation for another condition.

What scalp psoriasis looks like

• Thick or thin plaques with silvery-white scale
• Red, purple, or darker inflamed areas depending on skin tone
• Itching, burning, tightness, or soreness
• Scale extending beyond the hairline
• Similar plaques on elbows, knees, behind the ears, or elsewhere

On darker skin, psoriasis may look violet, gray, or dark brown rather than bright red. A dermatologist can distinguish it from seborrheic dermatitis, eczema, fungal infection, and contact allergy.

Why it happens

Psoriasis involves immune activity that speeds skin-cell turnover and produces inflammation. Genetics contribute to risk. Flares may be associated with stress, infection, skin injury, cold weather, smoking, alcohol, or certain medications, but triggers vary.

Can scalp psoriasis cause hair loss?

Inflammation, scratching, forceful scale removal, and tight hairstyles can cause temporary shedding and breakage. Psoriasis itself is generally nonscarring. Hair should regrow when the scalp improves unless another hair-loss condition is present.

Review medical conditions that cause hair loss if thinning continues after the plaques are controlled.

Over-the-counter treatment

Products containing salicylic acid can soften and remove scale. Coal tar may reduce scaling and itching for some people. Follow the label because excess use can irritate or dry the hair. Salicylic acid helps scale but does not treat every part of the immune process.

Anti-dandruff shampoos may help when seborrheic dermatitis overlaps with psoriasis, a situation sometimes called sebopsoriasis.

Prescription options

Dermatologists may prescribe topical corticosteroid solutions, foams, shampoos, oils, or sprays. Vitamin D analogues, tazarotene, or combinations may be used. Widespread or resistant psoriasis may need phototherapy, oral medicine, or biologic treatment.

The choice depends on severity, other affected areas, joint symptoms, pregnancy, health conditions, and previous response.

How to wash and style gently

1. Apply treatment directly to the scalp in sections.
2. Use only the contact time and frequency prescribed or labeled.
3. Loosen scale gently after it softens rather than picking it dry.
4. Condition the hair lengths to reduce tangling.
5. Use low to medium heat and keep dryers moving.
6. Avoid tight styles during active flares.

Scalp exfoliation can aggravate active plaques when it becomes scrubbing. Read the benefits and risks of scalp exfoliation before adding a brush or acid.

What not to put on a flare

Essential oils, undiluted vinegar, baking soda, and fragranced home remedies can irritate skin and trigger contact dermatitis. Heavy oil may loosen scale but can make medicated shampoo harder to distribute. Ask how to combine moisturizers with prescribed treatment.

When to seek care

See a dermatologist for severe pain, pus, fever, rapid hair loss, thick widespread plaques, or symptoms that do not respond to over-the-counter care. Joint pain, morning stiffness, or swollen fingers can signal psoriatic arthritis and should be discussed promptly.

Living with scalp psoriasis

Keep a simple record of products, treatment, stress, illness, and weather rather than changing many factors at once. Use fragrance-free hair products when sensitivity is present and wash hats and pillowcases regularly.

Tell your hairstylist about active plaques before color, bleach, relaxer, or adhesive use. Chemical services on inflamed or scratched skin can cause more irritation. Postpone the appointment when the scalp is sore, bleeding, or infected, and follow the dermatologist's plan first.
