Causes The most important cause for hair loss is inadequate nutrition. Even a partial lack of almost any nutrient may cause hair to fall. Persons lacking vitamin B6 lose their hair and those deficient in folic acid become completely bald. But hair grows normally after adequate intake of these vitamins. Another important cause is stress, worry, anxiety, trauma and sudden shock.
Stress leads to severe tension in the skin of the scalp.
This adversely affects the supply of essential nutrition required for the healthy growth of hair. General debility caused by severe or prolonged illness like typhoid, syphilis, chronic cold, influenza and anemia also give rise to hair loss, by making the hair weak. Diabetes and thyroid disorders are a major threat. Bacterial, viral or fungal infections can cause spot fall out of hair. It can however be treated with medicated shampoos and lotions.
