Aim: In this study, we aimed to determine the incidence of hair loss in patients who underwent laparoscopic sleeve gastrectomy (LSG), and to observe whether use of Biotin has an impact on hair loss. Methods: This study included 156 female patients who underwent LSG for obesity and completed a 1-year follow-up. All patients with vitamin deficiency were screened in the pre- and postoperative period. Hair loss was defined as the subjective perception of the women of losing a higher amount of hair when compared with normal situation. Results: Hair loss was observed in 72% of the patients after LSG (n = 112). Seventy-nine percent of the patients reported hair loss between the third and fourth-month interval, and continued for an average of 5.5 ± 2.6 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. İn 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 (P = .2). Conclusion: Temporary hair loss after LSG is common. It was found that biotin supplementation used to prevent hair loss does provide low efficacy.
