Thinning hair in women can be caused by a variety of factors, including genetics, aging, hormonal changes, medical conditions, and external factors. Here are some of the most common causes of thinning hair in women:
-
Genetics: Female pattern hair loss, or androgenetic alopecia, is the most common cause of hair loss in women and affects about 30 million American women. It has a strong genetic component and can be inherited from either parent.
-
Aging: As women age, hormone changes can cause hair follicles to shrink, resulting in shorter and finer strands of hair. Eventually, new hair no longer grows in those areas, leading to the appearance of sparse or thinning hair.
-
Hormonal changes: Hormonal changes due to pregnancy, childbirth, menopause, and thyroid problems can cause permanent or temporary hair loss. During menopause, estrogen and progesterone levels fall, meaning that the effects of male hormones are increased, which can lead to hair thinning.
-
Medical conditions: Medical conditions such as polycystic ovary syndrome (PCOS), anemia, and thyroid disorders can cause hair loss in women.
-
External factors: Overuse of damaging hair products, or tools such as dryers and other devices that heat the hair, can cause hair loss. Frequently wearing hairstyles that pull the hair too tight can also lead to hair thinning.
If you are experiencing hair loss or thinning, it is important to see a dermatologist to determine the underlying cause and develop an appropriate treatment plan.
