The term “trichoscopy” was first used in literature in 2008 and it refers to dermoscopy or videodermoscopy of hair and scalp. Trichoscopy is used for differential diagnosis of hair and scalp diseases, monitoring treatment efficacy in individual patients and evaluation of therapeutic or cosmetic products in clinical trials and animal experiments. Any handheld dermoscope or videodermoscope may be used to perform trichoscopy. Trichoscopy of lichen planopilaris depends on the stage of disease. In the active, inflammatory phase of the disease, the predominant trichoscopy feature is perifollicular scaling.
