Scalp Psoriasis Treatment Guide: What Really Works
What Is Scalp Psoriasis?
Scalp psoriasis is a chronic autoimmune condition causing red, flaky plaques covered by silvery-white scales on the scalp. It affects around 2–3% of the global population and is distinct from dandruff, though the two can coexist. The condition results from an overactive immune response that accelerates skin cell turnover, producing thick plaques that can extend beyond the hairline.
Recognising Scalp Psoriasis
- Well-defined red or pink plaques with dry, silvery scale
- Significant itching, burning or soreness
- Temporary hair loss in affected areas due to scratching
- Plaques may extend to forehead, neck and ears
Treatment Options
1. Medicated Shampoos
Anti-dandruff shampoos with ketoconazole, coal tar or salicylic acid help control the scalp microbiome and remove scale. Kezil SL Anti-Dandruff Shampoo (ketoconazole 2% + salicylic acid) is suitable as an adjunct for mild scalp psoriasis.
2. Topical Corticosteroids
First-line prescription treatment. Applied to plaques to reduce inflammation. Always use under dermatologist supervision to avoid side effects from long-term use.
3. Vitamin D Analogue Creams
Calcipotriol slows skin cell overproduction and reduces plaques. Often combined with a corticosteroid for enhanced efficacy.
4. Salicylic Acid Treatments
Keratolytic agents help soften and lift the thick scale, improving penetration of other topicals.
Lifestyle Management
- Avoid scratching — scratching worsens plaques and can trigger new lesions (Koebner phenomenon)
- Manage stress — a known trigger for psoriasis flares
- Maintain scalp hygiene without over-washing
- Use soft brushing to gently remove loose scale
- Protect scalp from sunburn while allowing moderate sun exposure (UV therapy can help)
When to See a Dermatologist
Seek professional care if plaques cover more than 20% of the scalp, are severely itchy or painful, do not respond to OTC treatments after 4–6 weeks, or are accompanied by nail changes or joint pain (which may indicate psoriatic arthritis).
