This girl I have been friends with since high school seriously commented on my status I posted about dying my hair saying its not safe at all to dye your hair while pregnant. I stated that my dr okayed it and told me as long as I use ammonia free and stay in an open room it is perfectly safe. She also stated theres no actaul evidence stating it travels to the fetus through the blood. It just assumed that it does because it can be absorbed into the skin. If it wasnt safe do you really think I would of dyed my hair at all while pregnant? I have done it twice since being pregnant and my son has not been effected by it. He is very healthy and thriving. Also not to mention after I commented back she posted a status saying some people are so stupid and that she cant even.
