Low iron, also known as iron deficiency anemia, is common, according to the MayoClinic.com. The most common symptoms are fatigue, weakness and pale skin. However, the MayoClinic.com notes that the condition can also cause hair loss. Women of childbearing age are most commonly affected due to iron loss during menstruation and pregnancy. Small children and those with iron-poor diets are also at risk. Although the deficiency can cause hair loss, you can prevent further loss and encourage new growth.

1. Consult your physician. Make absolutely certain that you have an iron deficiency and that your hair loss is not due to other factors. Your doctor may prescribe an iron supplement or other treatments to improve your iron counts.

2. Eat foods rich in iron. Leafy greens, whole grains and dried fruit are all rich in iron. Red meat, beans and eggs are also good sources of iron.

3. Get your vitamin C. Vitamin C contributes to hair growth and, according to a study published in the International Journal for Vitamin and Nutrition Research, helps the body absorb iron better.

4. Ask your doctor about birth control. Some forms of birth control prevent women from having periods every month and may reduce the amount of iron loss.

5. Stimulate your scalp. Mix 10 drops of peppermint essential oil and seven drops of rosemary essential oil into a 16-oz squeeze bottle of grapeseed oil. Squeeze a quarter-sized portion into your hand and massage the oil into your scalp once a day.

6. Get plenty of rest. Your body--including your hair follicles--repairs itself while you sleep. Get at least eight hours rest each night.
