Fazit
Despite selenium's role in thyroid function, research does not support supplementing with selenium to improve thyroid-related hair loss, and excess selenium may actually worsen hair problems.
- Mixed results across 35 studies — no consistent benefit for hair loss
- Selenium is important for thyroid health, but supplementation has not shown hair benefits
- Selenium toxicity is a known cause of hair loss — excess intake is risky
- Consult a healthcare provider before supplementing, especially for thyroid concerns
