Hair loss, also known as alopecia or baldness, refers to the loss of hair from the scalp or the entire body. It occurs due to disruption in the hair growth cycle. It can be hereditary or may occur due to medical illness, hormonal changes or drugs. It can affect men, women and even children. A normal individual sheds 50 to 100 hairs per day, but it is not noticeable as new hair growth occurs simultaneously.
Hair loss that occurs with ageing is usually hereditary and is the most common reason for baldness. In women, hair is considered to be an essential part of their identity, while in men, healthy hair is considered to be a sign of youth and vigor. Hair loss affects the appearance of an individual and hence causes psychological distress and inferiority complex. It can adversely affect the quality of life of an individual.
