Sudden hair loss in females can be caused by a variety of factors, including medical conditions, hormonal changes, and external factors. Some of the most common causes of sudden hair loss in females are:

• Medical conditions: Illnesses such as thyroid disorders, anemia, and ringworm can cause sudden hair loss in females. Polycystic ovary syndrome (PCOS) is another medical condition that can cause hair loss due to an imbalance of hormones.

• Hormonal changes: Hormonal changes due to pregnancy, menopause, or stopping birth control pills can also cause sudden hair loss in females.

• External factors: Overuse of damaging hair treatments, frequently wearing hairstyles that pull the hair too tight, and exposure to toxic substances such as chemotherapy and radiation therapy can cause sudden hair loss in females.

It is important to note that sudden hair loss in females can be distressing and may affect self-esteem and social lives. If you notice sudden or patchy hair loss, or more than usual hair loss when combing or washing your hair, it is recommended to talk to your doctor to determine the underlying cause and appropriate treatment.
