Fillers are frequently used in aesthetic medicine and, although usually safe, complications can occur. Vascular occlusion leading to tissue necrosis is a rare but severe complication. Alopecia after hyaluronic acid injection has been recently reported, being a vascular compromise the most probable physiopathological mechanism. The trichoscopic findings in this entity have not been described yet. A case report of a 30-year-old female who developed this complication following a hyaluronic acid injection as well as the description of the trichoscopic findings are presented in this report.
