Low iron and hair loss: what to know

Iron deficiency may push more follicles into a resting phase, followed by noticeable shedding across the scalp. Heavy menstrual bleeding, restricted diets, pregnancy, digestive disease, or ongoing blood loss can lower iron stores. Hair shedding can also reflect Telogen Effluvium, while inherited thinning, Alopecia Areata, scalp infection, and traction are separate possibilities.

A clinician may ask about diet, periods, recent illness, medicines, and family pattern, examine the scalp, and arrange blood tests for iron status and related causes. Take iron only when recommended; unnecessary supplements can cause side effects and delay finding the reason for low iron. Treating the cause can help the hair cycle recover, but visible regrowth takes time. Gentle handling and avoiding tight hairstyles can limit breakage.

Book a review for ongoing shedding, widening parting, scalp pain, scale, itching, or bald patches. Seek prompt care for fatigue with breathlessness, fainting, chest discomfort, or suspected significant bleeding. Sudden patchy loss, broken hairs with inflammation, or loss of eyebrows may need specific treatment rather than iron alone.

Ask which tests are needed, what may be causing low iron, how long treatment should continue, and whether your pattern also fits Female Pattern Hair Loss, Male Pattern Hair Loss, or another diagnosis.
