Conclusión

Research on biotin for telogen effluvium is mixed — it may help in some cases, especially if biotin levels are low, but it is not a reliable standalone solution for this type of hair shedding.

Results are mixed across 9 studies — some show benefit, others do not
Lower serum biotin levels have been observed in some telogen effluvium patients
Biotin was often studied as part of multi-ingredient supplements, making it hard to isolate its specific effect
Testing biotin levels before supplementing may help identify who is most likely to benefit
