3. Unhealthy Skin & Hair
Many health concerns will manifest signs in the skin and hair long before other symptoms appear. If your hair has become dry and brittle it may be a sign of too little iron in the blood. People who usually have glowing, healthy skin who suddenly start to suffer from dryness or flaking skin may also be suffering from an iron deficiency. Your blood carries much-needed oxygen to all of the cells in the body.
When there is an iron deficiency, the body will prioritize vital organs and systems in order to keep you alive. The hair, skin, and nails are often the first parts of the body to exhibit signs of iron loss. Hair that is not fed a steady supply of oxygen will eventually lose moisture and weaken. The skin will become dry and chapped as the cells begin to die from iron deficiency. In some serious cases of iron deficiency, hair may even fall out.
