If you're the type of girl who can never decide on a hair color then don't worry. You can keep up your hair dying regimen throughout your entire pregnancy, contrary to what many believe. There have been numerous studies on hair coloring and pregnancy and at this point there has been no evidence that coloring your hair causes birth defects. The Organization of Teratology Information Services (OTIS), which provides information on potential reproductive risks, says that animal studies are reassuring and that there are no reports of hair dye causing changes in human pregnancies, despite the fact that many women have colored their hair during pregnancy. OTIS also points out that very little of the chemicals in hair dye is actually absorbed into your system. That said, if you're still concerned, consider waiting to color your hair until the second trimester, when your developing baby is less vulnerable. Or you know, just don't do it at all.
