Kesimpulan

Research does not clearly support vitamin B12 supplementation for telogen effluvium — while low B12 is sometimes found in hair loss patients, there is no strong evidence that supplementation helps recovery.

Mixed results across 13 observational studies
Some post-COVID hair loss studies measured B12 levels without finding consistent patterns
No RCTs testing B12 supplementation for telogen effluvium
Only worth supplementing if a blood test confirms a B12 deficiency
