There are many reasons for adolescent hair loss, such as excessive pressure, bad living habits, genetic factors, etc., and it is not excluded that it is caused by disease.

1. Excessive stress: During adolescence, due to academic or life pressure, it often leads to emotional instability and hair loss.

2, bad habits: teenagers' bad habits can also lead to hair loss, such as staying up late, eating spicy food, often dyeing hair and so on. Because the adolescent hormones in this period are in an unstable state, it is easy to lead to endocrine disorder and increase of androgen, leading to excessive secretion of hair oil, which leads to the formation of hair loss. There is also insufficient intake of trace elements in the body, which can also lead to hair loss.

3, genetic factors: heredity is also closely related to hair loss, and the general male patients' hair loss is familial.

4, disease factors: some diseases can also lead to hair loss, such as seborrheic alopecia, pernicious anemia, thyroid dysfunction and so on. It is suggested that patients can go to a regular hospital to clarify the cause and treat them.
