Dry and Damaged Hair and Skin
Iron deficiency anemia may cause dry and cracked skin and hair. This is due to the fact when your body is deficient in iron, it guides its insufficient oxygen to more critical functions, such as the metabolism of the organs. When hair and skin are running short of oxygen and nutrients, it can become dull and weak. Hair loss can also occur in more severe cases of iron deficiency.
Experts say that it is quite normal for some hair (up to 100 hairs a day) to fall out during daily brushing or washing, but if you are losing much more than normal or clumps of hair, it may be an early indication for iron deficiency anemia.
