Pregnancy is a time when your body goes through a wide variety of changes – physical, emotional, and hormonal. Since your estrogen level increases, you should generally expect a full head of lustrous hair, but many women experience hair loss instead. Some of the reasons for hair loss during pregnancy are hormonal imbalances, nutrient deficiencies, genetic factors, side effects of medicines, anemia, discontinuation of birth control pills, and hypothyroidism. It is very important to take care of your hair during this phase. There are certain tips that can help you cope with hair fall, so that you can prevent it from becoming excessive, especially after your baby is born.
