ROS may be important mediators of cellular injury during COVID-19 sepsis (Silvagno et al., 2020), either following macromolecular damage or by hindering extracellular and intracellular regulatory processes
Since SARS-CoV-2 activates mitochondrial ROS-mediated feedback loops that produce long-term changes in the redox status and endothelial function of the host, leading to cardiovascular disease and lung injury (Chang et al., 2021), and endothelial cells are key players in inflammatory pathologies, such as acute respiratory distress syndrome, thrombosis, and atherosclerosis
The inhibition of glutathione peroxidase 4 (GPX4) or the depletion of glutathione (GSH) leads to ferroptosis by excessive lipid peroxidation and elevated intracellular lipid ROS
The good news: this type of hair loss is usually temporary once the triggering factor resolves
