Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Ferritin is a protein that stores and releases iron in the body, and its blood levels serve as a key indicator of total body iron stores. There is significant scientific evidence linking low ferritin levels to hair loss, particularly in the form of telogen effluvium, a condition where more hairs than usual enter the shedding (telogen) phase of the hair growth cycle. Several studies have demonstrated that women with unexplained diffuse hair loss often have lower serum ferritin levels compared to controls. For example, a 2003 study in the Journal of Investigative Dermatology found a correlation between low ferritin and increased hair shedding. Other research has indicated that restoring ferritin to optimal levels (often cited as above 40-70 ng/mL) can help reduce hair loss and promote regrowth, especially in premenopausal women.

While iron deficiency is a well-known cause of anemia, its impact on hair health is specifically attributed to the role of iron in cell proliferation and the hair follicle growth cycle. However, it should be noted that not all cases of hair loss are related to low ferritin or iron deficiency, and excessive iron supplementation can be harmful. Thus, scientific guidelines recommend assessing ferritin levels in individuals with unexplained hair loss and considering iron supplementation only if levels are low. Overall, the use of ferritin as a marker and target for supporting hair health is supported by strong scientific evidence.
