Iron is critical for producing hemoglobin, a protein that helps red blood cells deliver oxygen throughout your body. When you don’t have enough iron, your body can’t produce the hemoglobin in your blood. Hemoglobin carries oxygen for the growth and repair of cells in your body, including the cells that stimulate hair growth.
This may result in excess hair shedding or bald patches in advanced iron deficiency.
If you think you are experiencing hair loss because of iron Deficiency, contact your doctor for a ferratin level blood test.
