"Although fairly limited, most research indicates the chemicals found in both semi-permanent and permanent dyes are not highly toxic and are safe to use during pregnancy. In addition, only small amounts of hair dye may be absorbed by the skin, leaving little that would be able to reach the fetus. As such, this small amount is not considered harmful to the fetus." From *****************. org. It also states you could wait till your second trimester.
I waited till the second trimester to dye hair because it could harm your baby before. But I would ask the doc to confirm and rest of mind. Hope I helped you :)
There is no medical research to support that u can't do any of these things. They are all fine. Ask ur doc or do sum research on web md.
Even certain skin products can be harmful. Everything u do to yourself you do to the baby. In my culture we are not supposed to cut our hair when we are pregnant. I am first nations and we hold a lot of power and energy in our hair.
You can cut nd wash your hair but perm nd dye can be dangerous to the baby because of the chemicals in the products if you want to perm or dye your hair it's better to wait till second trimester nd get clearance from your doctor. Good luck
