I know to be safest we should just avoid all chemicals — which I have thus far at 27 weeks. Been doing my nails at home with nontoxic polish and haven’t gone to the salon for any upkeep. But we’re getting married next month and I really wanted to update my hair for it, I’m just wondering if anyone has strong information on whether a hydrogen peroxide “base bump” is risky to baby? It does go on the scalp which I know is not ideal but it’s only for a few minutes. Not as long as highlights take.
