Alopecia threshold hypothesis. Illustrated are three hypothetical patients (1, 2, and 3). The height of the bars indicates the predisposition of each patient to developing alopecia. The dashed line indicates the threshold at which alopecia develops. In this model, low body iron (Fe) stores decrease the threshold for developing different types of alopecia. NL, normal.
