Hair loss in women can be caused by a variety of factors, including genetics, hormonal changes, medical conditions, and external factors. The most significant cause of hair loss in women is female-pattern hair loss (FPHL), which affects about one-third of susceptible women, which equals out to some 30 million women in the United States. During menopause, changing levels of hormones can cause hair to thin, and hair follicles may shrink, leading to slower hair growth and easier hair loss. Other medical conditions that can cause hair loss in women include thyroid disorders, anemia, and polycystic ovary syndrome (PCOS) . External factors such as excessive hairstyling or hairstyles that pull the hair tight, such as pigtails or cornrows, can cause a type of hair loss called traction alopecia. Stressful events, such as childbirth, illness, or surgery, can also cause hair loss.

It is important to note that hair shedding is part of a natural balance, and humans shed between 50 and 100 single hairs per day. When the balance is interrupted, hair loss happens. If you are experiencing hair loss, it is recommended to see a healthcare provider to determine the underlying cause and develop a treatment plan.
