Post-COVID Telogen Effluvium

Recently, the number of patients with acute telogen effluvium (ATE), among other forms of hair loss, has increased in comparison with previous years. The COVID-19 pandemic, taking place during this period, may be the cause of this phenomenon. The exact mechanisms by which this virus causes hair loss are not entirely understood; still, the most likely cause is an excessive release of proinflammatory cytokines during SARS-CoV-2 infection. This process can trigger the development of telogen effluvium (TE) by damaging hair matrix cells. Additionally, the psychosocial condition of patients recovering from COVID-19 will have deteriorated, contributing to hair loss. Based on data collected until now, post-COVID TE is expected to improve without any treatment. Although there is no specific treatment for post-COVID TE, eliminating psychophysical stress, managing systemic complications, and explaining the course of the condition to the patient will potentially improve and speed up the hair recovery process.
