Can zinc deficiency cause hair loss?

Zinc deficiency may indeed trigger hair loss. Hair shedding could be attributable to zinc deficiency, although other underlying causes are also possible. Zinc deficiency compromises hair health, resulting in dull, brittle, and easily shed hair. It may also cause hair to become dry, yellowish, thin, and sparse—signs suggestive of malnutrition.

Hair loss may stem from deficiencies in trace elements—including calcium, iron, and zinc. A trace-element blood test at a hospital can help identify such deficiencies. If zinc deficiency is confirmed, zinc supplementation may promote hair regrowth. Additionally, maintaining a balanced, nutrient-rich diet is crucial. Besides hair loss, zinc deficiency may also present as white spots on the nails, decreased appetite, anorexia, pica (craving non-food substances), dermatitis, night blindness, and weakened immunity.

Hair loss may also result from other conditions, such as seborrheic dermatitis or excessive androgen secretion. Medical treatment—including pharmacotherapy—and dietary modifications can help manage hair loss. In severe cases, hair transplantation surgery may be considered.

Daily scalp hygiene and care are essential. Ensure adequate nutritional intake, emphasizing foods rich in protein, vitamins, and dietary fiber—such as beef, eggs, and celery.
