Fazit
Despite frequent associations between low vitamin D and telogen effluvium, research does not clearly support vitamin D supplementation as an effective approach for this type of hair shedding.
- Lower vitamin D levels are common in telogen effluvium patients but may not be the cause
- No well-designed RCTs demonstrate that supplementation resolves telogen effluvium
- Post-COVID hair loss studies show inconsistent findings regarding vitamin D
- Correcting a deficiency is reasonable, but vitamin D alone is unlikely to resolve hair shedding
