According to Pregnancy Birth and Baby, many new moms see noticeable hair loss a few months after having a baby－dermatologists refer to this condition as excessive hair shedding, which is caused by falling estrogen levels. Hormones, stress or medical conditions may occur during or after pregnancy.
What cause hair loss during pregnancy & childbirth?
During pregnancy, the flood of estrogen levels is rising higher to support baby, and the natural cycle of hair follicle is shedding. As a result, some women may lose fewer hair after the baby comes. It would take up to 2 years for your locks to return to normal.
Hormonal Shifts- As hormones change to accommodate the developing baby, generally in four months postpartum.
Thyroid Problems- Too much or too little thyroid hormone will affect 2 or 3 out of 100 pregnant women, especially hyperthyroidism. The symptom includes hair loss, muscle cramps, constipation and exhaustion.
Iron Deficiency- Low iron is another common cause of hair loss during pregnancy. When your blood supply surges to deliver blood and oxygen to the baby, iron deficiency anemia may occur easier. Low iron levels mean that there’s no enough red blood cells to efficiently carry oxygen through your body, so it’s better to address your iron levels, especially in pregnancy or period time.
