Is it safe to dye my hair when I'm pregnant?

We don't know much about the safety of hair dyes during pregnancy. It's likely that when you apply hair dye, only a small amount is absorbed into your system. So very little chemicals, if any, would be able to get to your baby. In the few animal and human studies that have been done, no changes were seen in the developing baby. Talk with your doctor if you have questions or concerns.
