Can low ferritin levels cause alopecia areata?

Low ferritin levels, which indicate depleted iron stores in the body, can contribute to hair loss, but they are not a direct cause of alopecia areata. Alopecia areata is an autoimmune condition characterized by sudden hair loss due to the immune system attacking hair follicles. While some individuals with alopecia areata may also have low ferritin, addressing iron deficiency alone may not resolve the autoimmune aspect of the condition. It's essential to consult a healthcare professional for a comprehensive evaluation and treatment plan.
