You won’t be surprised to learn that following labor, hormone levels can fall dramatically. Although they should land at your regular levels, the relative change can be enormous. And that can lead to hair loss as you body readjusts to non-pregnancy hormone levels. In addition, labor can highlight underlying hormone issues that result in hair loss, including an underactive Thyroid gland. So, if you’re three to six months postpartum and losing more hair than usual, please talk to a doctor to rule out underlying causes.
