According to Ayurveda, the hair is derived either as a by-product or produced as a breakdown product of Asthi (bone tissue). Any disturbance in this tissue metabolism, which very much depends on the digestive fire, can affect the health of the hair. To a certain extent, the quality of hair depends on the body constitution.
The reason for hair loss is a subject that no two doctors, seem to agree on and everyone seems to have their own opinion on the subject. The major causes of hairfall are hormonal, nutritional deficiencies and complication to other diseases and medications. Hormone related hair fall may also result from an increased sensitivity of hair follicles to male hormones or due to greater number of male hormone receptors attached to hair follicles. This is the component that is inherited through the genes — termed as Pitta constitution.
According to Ayurveda, excess of Pitta dosha in the body is increased by hot climatic conditions, excessive intake of spicy, salty and sour food, hot and sharp food, tea, coffee, alcohol, meats and excessive smoking. Eating too much fried, oily, greasy, and acidic foods also aggravates Pitta. Pitta balancing herbs (Eg: Shatavari —Asparagus) and vegetables which improves the quality of Asthi dhathu (Eg: bitter vegetables) are effective in treating hair fall.There are a number of other causes for hair fall like acute illness, high stress, and thyroid imbalance, certain drugs, sudden weight loss and high fever.
The first step is to locate the root cause in your diet or lifestyle that may be increasing the Pitta dosha. Once you locate it, try to give up or at least reduce the diet, habit, or activity responsible for increasing Pitta. Internal use of Ayurvedic medicines like Thikthakam kashayam, Thikthakam ghritham as per medical advice are effective to correct the metabolism. Ayurvedic general tonics like Narasimha rasayanam, Chyavana prasam are effective for improving hair growth. In alopecia, due to systemic diseases, treatment of the same is also required.
