Delphi Consensus on the Distinct Clinical and Histopathological Features of Lichen Planopilaris and Frontal Fibrosing Alopecia: Insights From the Hair Diseases <scp>EADV</scp> Task Force

While moderate consensus supports FFA as a variant of LPP, uncertainties remain regarding its demographic distribution, the presence of vellus hairs, and blue-gray dots. The study refines diagnostic and management approaches but is limited by the absence of dermatopathologists and basic researchers.
