Is it true that iron deficiency in women can cause hair loss that may appear to be AGA? If so, does supplementation actually help?

Also, do you know if oral birth control pills (Ortho-tricycline lo) can cause progressive hair loss while on them. I am not refering to hair loss after discontinuing but progressive loss over time.

Iron deficiency with or without anemia has been reported as a cause of hair loss. Hair loss seen in iron deficient patients is typically more diffuse. In patients who are prone to male pattern baldness, iron deficiency can speed up the hair loss process.

Birth control pills or medications that manipulate the estrogen balance can cause hair loss as well. Although any medication containing estrogen may cause hair loss, the opposite also occurs and in some situations estrogen may be protective. Excessive hair loss (telogen effluvium) could be often seen in withdrawal from estrogen, or in postpartum phase and can last about a year after the baby is born.
