What Causes Hair Loss?

Published on January 12, 2018

Healthy hair gives off an overall impression of youthfulness and good health. Unfortunately, pollution, dust, unhealthy food habits, genetics, low iron levels, thyroid issues, stress, and hormonal imbalance have made hair loss a common problem.

Alopecia Areata

The word Alopecia means hair loss. It is an autoimmune disease that causes the immune system to mistakenly attack hair follicles. Because these biological structures contain hair roots, this causes hair loss. The damage may not be permanent, however, depending on whether the individual hair grows back and if the condition lasts for many years.

Genetics is sited to be the cause for Alopecia Areata. A permanent cure isn’t available, but the condition can be treated for a time. The treatment involves injections of corticosteroids into the scalp.


Heredity is a common cause for hair loss. In the initial stages, the hair often weakens, and this advances to complete hair loss on parts of the scalp. The pattern differs for men and women. Hair loss is widespread but well hidden in women. In men, hair loss begins at the temples and continues in an M-shaped pattern.

Vitamin Deficiencies

Vitamin A, vitamin C, zinc, magnesium, and iron are the nutrients required for healthy hair. These vitamins have to be consumed externally, since they aren’t produced in our body. If they are not consumed in the right amount, it affects the growth of hair.

Thyroid Issues

If the thyroid gland produces excess or deficient thyroid hormone, it affects the hair growth cycle.


In this fast-paced world, we are frequent victims to stress. Physical stress like trauma, surgery, or an accident can cause hair loss. Stress affects the growth cycle of hair and can cause excess hair to shed. Meditating and participating in relaxing activities are known to be good stress busters.


Ringworm is a fungus that affects the scalp, causing hair to fall out in round patches. Ringworm infections disappear on their own, and some cases can be eradicated with the help of home remedies. If the infection is extreme, treatment may be necessary.


Trichotillomania is a hair-pulling disorder. Individuals are cited to have irresistible urges to pull hair from the scalp. This leads to patchy and bald heads. The severity of the disorder can vary from mild to manageable and uncontrollable. Cures are available to treat this disorder.


Anemia, or iron deficiency, causes hair loss and is common among women. It reduces the capacity of blood to absorb oxygen, which in turn reduces the oxygen content in the body. In order to continue to support the vital functions of the body, oxygen supply to keep the hair intact is reduced.


Blood-pressure medications, anti-depressants, methotrexate, lithium, and anti-inflammatory drugs are examples of medicines that can cause hair loss.
