hair loss first trimester

You may have heard that hair becomes thick and lustrous during pregnancy. This may be true for some women, thanks to high levels of the hormone estrogen, which slows hair shedding. Other moms-to-be, however, experience thinning hair or hair loss either during pregnancy or in the months immediately following birth. While concerning, hair loss is normal and can be caused by things like hormones, stress on the body, or medical conditions that accompany pregnancy.
