Telogen effluvium (TE) is one of the most common form of hair loss in women. Many triggers have been identified, as stress, drugs, trauma, endocrine disease, nutritional deficiencies, and febrile states. We report three cases of TE occurred after severe Sars‐Cov‐2 infection and provide our clinical management, according to Sars‐Cov‐2 hygiene measures. Only one case report has been found in the literature associating anagen effluvium during severe Sars‐Cov‐2 infection. Other studies reported the exacerbation of a preexisting TE, correlated to the stress of lockdown. In our cases, patients never had a TE diagnosis before and did not report previous evident hair loss. TE can be associated with post severe Sars‐Cov‐2 infection. From our revision of the literature, this is the first case‐series describing TE in post severe Sars‐Cov‐2 patients. Further studies are needed to evaluate the relationship between TE and Sars‐Cov‐2 infection.
