im not sure it is complete safe but i dont see why its a problem
No. The chemicals in the dye can get in your blood stream and transfer to your baby. There are other chemicals you should avoid such as splenda. Do a google search for things to avoid while pregnant.
Of course you can - so long as you're not planning on drinking the dye !
Pregnant woman can cut their hair but not dye or highlight their hair while pregnant because of harmful chemicals in the dye.
I believe after a few months .. 2-4 or something .. it's safe to dye your hair in general. I'm not positive, seeing as I've never been pregnant. But I know my mother's friend dyed her hair when she was pregnant and her baby's fine. You're just not supposed to dye it in the early stages of the pregnancy.
It is not advisable for pregnant women to dye thier hair due to the chemicals involved.
