What causes hair loss after bariatric surgery?

After bariatric surgery, hair loss (called telogen effluvium) may be caused by:
  • trauma from the surgery itself and rapid weight loss
  • change in hormone levels
  • nutritional deficiencies
A lack of iron, zinc and protein in the diet are the main contributors to hair loss. Vitamin A, inositol, folate, B6 and essential fatty acids also are associated with hair health.

Up to half of people who have had bariatric surgery experience hair loss, typically three to six months after the procedure.
