Can zinc deficiency cause hair loss?
Zinc deficiency can contribute to hair loss, as zinc plays a role in protein synthesis, cell division, and the normal function of hair follicles. Some studies have found lower zinc levels in individuals with certain types of hair loss, and correcting a deficiency may support hair regrowth in some cases. However, evidence is inconsistent and differences are often small, so the clinical significance remains uncertain.
Key points:
- Zinc supports normal hair growth through its role in cell division and follicle function.
- Low zinc levels have been associated with increased hair shedding in some individuals.
- Evidence linking zinc deficiency directly to hair loss is inconsistent.
- Excess zinc intake may also contribute to hair shedding.
