Re: question..
Getting highlights is safe, as the dye doesn't touch the scalp.I've gotten them in both pregnancies, asked my O.B's beforehand , and researched quite a bit. Dyeing is not good at all , as it dyes your hair and touches the scalp, which could go into the bloodstream, but thats not the case with highlights.
Anyway, you could ask your doctor in your next visit, just to be safe.
