Iron Deficiency and Nonscarring Alopecia in Women: Systematic Review and Meta-Analysis PMC

A person with severe anemia may also have pallor in the creases of the palms of the hands. However, tiredness that occurs with pallor, shortness of breath, and other symptoms may be a sign of anemia. Iron plays a crucial role in your body across the board, getting oxygen to where your body needs it and as a result, giving your muscles and organs what they need to get active [1]. “Taking iron with vitamin C, as is found in citrus fruits (like lemons and limes) or some combination of supplements, increases the stomach’s absorption of iron,” says Dr. Piliang. Get more iron in your diet by adding supplements or changing your eating habits. Those who are vegetarian or vegan may want to focus on including foods that are good sources of iron.

Biotin supplementation has been successful in the treatment of brittle nails [137]. 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. Iron deficiency is the medical term for when you have too little iron in your blood. Iron is an essential trace element, and we absorb it naturally from foods we eat or supplements such as iron tablets. Iron deficiency can be due to poor diet, but is more commonly linked to internal bleeding or, in women, heavy periods or pregnancy.

The telltale signs of  these conditions are chronic inflammation of the scalp and the scarring of hair follicles, which can result in irreversible hair loss, Agbai notes. Baldness is often hereditary, and is activated by a shift in your hormones. By contrast, scarring alopecia, another autoimmune disease that causes hair loss, is often accompanied by itchiness, tenderness and scaling of the scalp. Scarring alopecia is the most devastating type of hair loss, Mirmirani says, because it permanently destroys the hair follicles. When experiencing hair loss, ask your healthcare provider to screen you for low iron levels and supplement if needed.

Red blood cells are important for the transfer of oxygen throughout your body. Without enough red blood cells, your organs and major systems don’t work as effectively. In time, however, you may notice that the insides of your eyes are paler than usual, and you may feel tired and short of breath. People who are pregnant or have heavy menstrual periods have the highest risk and should talk with a doctor about being tested for iron deficiency anemia. Iron deficiency lowers the level of hemoglobin in your blood, which may reduce the amount of oxygen available to cells that cause hair growth. Shortness of breath is a symptom of iron deficiency, since low hemoglobin levels stop your body from effectively transporting oxygen to your muscles and tissues.

Researchers have called for more double-blind placebo studies to examine the role of vitamin and mineral intake on hair loss. Data correlating TE and AGA with zinc level are not homogenous, and screening for zinc is not recommended. However, comprehensive studies are lacking, which preclude any recommendation for screening of selenium or riboflavin. The presence of biotin can in fact interfere with tests that use biotin–streptavidin technology.

Staying Healthy

If you believe your hair loss is related to an iron deficiency, it’s important to consult with a healthcare provider before taking matters into your own hands. It may seem tempting to self-diagnose and take an iron supplement, but they do have side effects, and your good health intentions may end up leading to more severe health problems. Doktor tells us that once an iron deficiency is diagnosed, you'll want to pin down the cause. That's to ensure that once the problem is treated, it won't happen again.

After age 6 months, start feeding your baby iron-fortified cereals or pureed meats at least twice a day to boost iron intake. After one year, be sure children don't drink more than 20 ounces (591 milliliters) of milk a day. Too much milk often takes the place of other foods, including those that are rich in iron. If you or your child develops signs and symptoms that suggest iron deficiency anemia, see your doctor. So see your doctor for a diagnosis rather than taking iron supplements on your own.

Follow-Up Testing

Encouraging hair regrowth is a matter of getting those iron stores replenished. However, the research does suggest that iron deficiency hair loss seems to be related to hair loss that does not scar the hair follicles. This is promising for regrowth because it means that the follicles are not severely damaged and may be able to grow hair again. Female pattern hair loss usually refers to thinning hair in the middle portion of the scalp.

However, there is currently limited information on the effects of zinc supplementation on hair growth in those without documented deficiency. One report described a single patient with alopecia, without clear deficiency, who experienced improvement following oral zinc therapy [40]. Iron deficiency can be diagnosed with blood tests, endoscopy, or a bone marrow biopsy. Treatment involves correcting the underlying cause and replacing lost iron.

Women may notice that their part is becoming wider or that their scalp is more visible. Most adults shouldn’t consume more than 10,000 international units (IUs) of vitamin A daily. If you’re supplementing with vitamin A and notice hair loss, talk with a healthcare provider. Genetic causes of biotin deficiency can be either neonatal or infantile.
