Fazit
Research does not support selenium supplementation for hair loss — in fact, excessive selenium intake has been associated with hair loss, so supplementation without a confirmed deficiency is not recommended.
- Mixed results across 35 studies — no clear benefit for hair loss
- Both selenium deficiency and excess may contribute to hair problems
- Case reports have linked selenium supplements to hair loss and nail damage
- Only supplement if a healthcare provider has confirmed a deficiency
