Seventy-nine percent of the patients reported hair loss between the third and fourth-month interval, and continued for an average of 5.5\u2009\u00b1\u20092.6 months. Permanent alopecia was not observed in any of the patients. Patients who experienced hair loss and Biotin deficiency after LSG were prescribed 1000 mcg\/day of Biotin for 3 months. Of these 22 patients; only 5 (23%) patients reported a remarkable decline in hair loss. \u0130n addition, 29 patients were found to take 1000 mcg\/day of Biotin for average 2.5 months after onset of hair loss by their own initiative, despite optimal blood Biotin levels. Eleven (38%) patients reported a remarkable decline in hair loss. The effect of biotin use on hair loss in patients with and without biotin deficiency was compared. There was no significant difference (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      \u2009=\u2009.2).\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion:<\/jats:title>\n                    <jats:p>Temporary hair loss after LSG is common.
