Iron may support recovery from telogen effluvium, particularly when low ferritin levels are confirmed, but the evidence is mixed and routine supplementation without testing is not well-supported.

56 studies provide substantial evidence, though results are mixed across the research
Lower ferritin levels are commonly found in patients with telogen effluvium
One study found iron supplementation improved satisfaction even in patients without overtly low ferritin
Blood testing for ferritin and iron levels is recommended before starting supplementation
