Actually, hair loss is mainly caused by frequent urination, urgency, and incomplete bladder emptying, which are usually caused by urinary system infections. This situation is more common in female patients due to the characteristics of the female urethral structure and changes in estrogen levels within the body, which make these symptoms more likely to appear.

Additionally, it could also be caused by urinary tract obstruction, which is generally more common in male patients. However, whether male or female, the appearance of symptoms such as frequent urination, urgency, and incomplete bladder emptying can lead to feelings of irritability, depression, and gloominess, hence the occurrence of hair loss. It is recommended to seek examination and treatment at a formal hospital in such cases.
