Lichen planopilaris is an inflammatory, primary cicatricial alopecia that presents with different hair loss patterns. Similar to lichen planus, the etiology of lichen planopilaris is unknown but is presumably related to the cause of lichen planus. Lichen planopilaris results in patchy, progressive, permanent hair loss, mainly affecting the scalp while also extending to other hair-bearing regions such as the eyebrows and pubic area. Understanding the nature of autoimmune diseases and the role of inflammatory processes is crucial in guiding treatment decisions.
The epidemiology of lichen planopilaris, a dermatological condition, is also unclear. Recent evidence-based approaches advocate for the use of corticosteroids, topical tacrolimus, antimalarial drugs, and emerging treatments such as JAK inhibitors. In addition, patient education, interdisciplinary collaboration, and long-term management strategies are critical for improving functionality, considering the significant impact on lifestyle and appearance.
