Hair loss often is a result of different causes like heredity, anaemia, nutritional deficiencies, stress and medical problems like thyroid disorder, diabetes mellitus and polycystic ovarian syndrome (in females). The selection of hair loss treatment should be therefore based on diagnosing the root cause of it, extent of hair fall, and condition of the hair and scalp.
Also, hair loss not only affects our appearance, but also 'hurts' our pride and affects our psyche. Hair loss is strongly linked with depression and can be an early sign of a heart disease.
