Telogen Effluvium and COVID-19

The document presents a case of post-COVID-19 telogen effluvium, a condition of hair loss, in a 39-year-old hypertensive and obese patient who had a history of moderate COVID-19 four months prior. The hair loss was attributed to the previous episode of COVID-19 after other possible causes were ruled out. The authors suggest that the persistent fever, cytokine storm, and the entire immunological cascade of COVID-19 can lead to apoptosis of the keratinocytes of the hair follicles, initiating the catagen phase early followed by the telogen phase with consequent hair loss. The authors recommend careful observation and clinical follow-up of patients with late symptoms possibly secondary to COVID-19, as the late consequences of the disease are not yet fully known.
