Telogen Effluvium Post COVID-19 Infection: A Narrative Review

This narrative review discusses the occurrence of telogen effluvium, a type of hair loss, following COVID-19 infection, typically appearing three to six months after the illness. The condition may be related to the inflammatory response and altered anticoagulation mechanisms caused by the virus. Diagnosis involves ruling out other causes of hair loss and may use tests like trichogram and phototrichogram. Treatment includes addressing the viral infection and its psychological effects, with stress reduction being important. Nutritional support and topical treatments such as Minoxidil are recommended, although patients should be aware of potential initial hair shedding. Intradermal Minoxidil may offer benefits due to better absorption. Regular hair washing is also advised to help recovery. The review calls for more research to better understand the link between viral infections and hair loss and to develop new treatments.
