What are everyone's thoughts on coloring hair during pregnancy? Some say it's safe others say not to do it. I haven't done mine in months because I just don't want to put the baby at risk.
There are a lot of chemicals used in hair dye, but no well-designed studies have found any direct link to birth defects or childhood cancers. You don't want to be exposed constantly, dyeing your hair once or twice is unlikely to be a major problem. To be on the safe side, wait till the second or third trimester, when most of baby's major organs have finished developing, or opt for highlights over single-process color. Since highlights aren't applied directly to the scalp, the chemicals are significantly less likely to enter your bloodstream.
