Hair loss and low ferritin: what should you know?

Ferritin reflects stored iron, and a low result can prompt questions about dietary intake, heavy menstrual bleeding, blood loss, absorption, or another health issue. Hair shedding related to a physical or nutritional strain is often diffuse and may fit Telogen Effluvium. Low ferritin does not explain every pattern: smooth patches can occur with Alopecia Areata, while a widening part or crown thinning may fit Female Pattern Hair Loss or Male Pattern Hair Loss. The laboratory result should be interpreted with the rest of the blood count, symptoms, and history.

Share the full laboratory report and mention fatigue, breathlessness, dizziness, dietary restrictions, digestive symptoms, menstrual flow, pregnancy, and any bleeding. Ask what is causing the low iron stores before choosing a supplement. Include iron-containing foods alongside a balanced diet, but follow clinician advice about replacement because iron is not suitable for everyone and can interact with medicines. Continue gentle hair care and document shedding with photographs.

Arrange medical review for low ferritin with persistent shedding, marked fatigue, dizziness, breathlessness, palpitations, black stools, or unusual bleeding. Seek urgent care for fainting, chest pain, severe breathlessness, or heavy active bleeding. A dermatology assessment is also useful when loss is patchy, the scalp is inflamed, or shedding does not match a diffuse pattern.

What does my ferritin result mean alongside my blood count? Why might my iron stores be low? Do I need further tests or replacement, and how will it be monitored? Could another hair-loss pattern be present at the same time?
