Iron deficiency can potentially cause hair loss, although there is conflicting evidence about the relationship between the two. Iron is an essential component in an enzyme called ribonucleotide reductase that helps cell growth, and hair follicle cells can be particularly sensitive to decreasing levels of iron. However, research has determined that there is not enough evidence to say for sure that iron deficiency anemia can cause hair loss in men or women. Nevertheless, doctors do know that iron deficiency can play a role because many people experiencing hair loss have lower iron stores than those who are not losing their hair. Iron deficiency hair loss seems to be related to hair loss that does not scar the hair follicles, which is promising for regrowth because it means that the follicles are not severely damaged and may be able to grow hair again.
If you think your hair loss is related to an iron deficiency, it is best to consult a doctor to measure your iron levels. Your doctor will most likely order a ferritin level blood test, which measures the levels of a protein called ferritin that helps store iron. If you have a low level of ferritin, your doctor will likely recommend iron supplements to tackle both this and any effects it has had on your body, including hair loss. However, it is important to note that potentially excess iron can trigger hair loss, whether it’s due to a genetic condition such as haemochromatosis (where the body stores too much iron) or taking too many iron supplements. Therefore, it is essential to consult a doctor before taking any supplements.
