Sonuç
Biotin may help support hair regrowth when hair loss is related to a nutritional deficiency, but the evidence is moderate and works best when an actual biotin deficiency is confirmed.
- 6 out of 10 studies show positive effects of biotin on nutritional deficiency-related hair loss
- Most supportive evidence comes from cases where biotin deficiency was confirmed through blood tests
- The total participant pool is small (134 people), so results should be interpreted with caution
- Biotin is generally well-tolerated, but may interfere with certain lab test results
