Conclusión

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
