This condition is still being researched, but the hormone influences in hereditary hair loss in females are suspected to be different from those in males. Some of the less common causes of hair loss, which are reversible with treatment, include thyroid disease, iron deficiency, high fever, surgery or general anaesthesia, “crash diets”, childbirth and certain medications. There are also certain dermatologic scalp disorders that can result in temporary or permanent hair loss, such as Lupus, Lichen Planopilaris, and Alopecia Areata.
