The most common age group was between 21 and 30 years (51.9%). Out of 991 participants who were included in the current analysis, 670 (67.6%) reported post-vaccination hair fall. The probable causes of post-vaccination hair fall were vaccine-related in 185 (27.6%) participants, other causes in 326 (48.7%) participants, and unclear in 326 (48.7%) participants. Post-vaccination hair fall was significantly higher among females compared with males (68.5% versus 57.9%,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.036), those who did not suffer compared with those who suffered from hair fall before vaccination (72.1% versus 63.4%,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.003), and those who did not report compared with those who reported preexisting conditions that might be related to hair fall (74.5% versus 57.3%,\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      &lt; 0.001).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>We are reporting a high prevalence of post-vaccination hair fall, which affected approximately two-thirds of participants who received COVID-19 vaccines.
