Psoriasis of the Scalp

The 2001 article reviewed the diagnosis and management of scalp psoriasis, a condition affecting about 2% of the Western population. It highlighted the use of coal tar shampoos and salicylic acid as effective treatments, despite the lack of double-blind studies for coal tar. Topical corticosteroids were the most commonly used treatment, with effects seen within 3-4 weeks, but their long-term safety and efficacy were not well-documented. Vitamin D3 analogues like calcipotriol showed substantial antipsoriatic effects and were often combined with corticosteroids to enhance results and reduce irritation. Systemic treatments such as methotrexate, cyclosporine, and acitretin were reserved for severe cases but carried risks like hematopoietic suppression, liver and kidney impairment, and potential hair loss with acitretin. The article emphasized the need for long-term management strategies to improve outcomes and minimize adverse effects.
