Hair loss linked to iron deficiency

Hair loss and iron deficiency are often connected, with iron deficiency being a common cause, particularly in women, according to Dr. Dima Haidar, a dermatologist known under the pseudonym docteur_skin on social media.

Iron's role in hair growth

Iron is a crucial element for the growth of hair follicles, but in women, iron reserves are often very low. This can impact the health of hair follicles and lead to hair loss.

Diagnosing iron deficiency

When there is a suspicion of iron deficiency, a biological assessment through a simple blood test is recommended. Measuring ferritin levels allows for the assessment of iron reserves, as ferritin is the molecule that stores iron.

Low ferritin and its effects

If ferritin levels are below the minimum required, it can indicate low iron reserves, which may be used for more critical functions such as red blood cell production, leaving less for hair follicles.

Dietary sources of iron

To maintain healthy hair follicles, it is important to have sufficient iron reserves, which can be achieved through a varied diet. Foods rich in iron include black pudding, poultry liver, certain shellfish, beef, sardines or mackerel, seeds, tofu, dried beans, lentils or chickpeas, eggs, spinach and other green vegetables.

Absorption of plant-based iron

However, the iron in plant-based foods is often less well absorbed by the body. For vegetarians, it is recommended to combine plant-based iron sources with vitamin C to enhance absorption.

Managing iron intake

It is also advised not to take iron supplements without consulting a doctor, who can recommend an appropriate treatment.
