Abstract
Lichen planopilaris (LPP) is a cell-mediated scarring alopecia that causes inflammation of the scalp and the eventual destruction of hair follicles in affected areas. Current literature on treatment of LPP remains limited with no definitive treatment approach being recognized, although a combination of topical/intralesional steroids and orally administered hydroxychloroquine remains the most utilized option. Low-level light therapy (LLLT) is an expanding technology shown to be effective in a variety of dermatologic conditions. We report here four patients with LPP who show a dramatic response to LLLT, including a reduction of inflammation, disappearance of symptoms, and evident hair regrowth with no side effects. We review the possible role of LLLT in LPP and other lichenoid conditions.
