These days, most mommies-to-be try to avoid getting chemical hair treatments while they’re expecting – especially haircolor. The idea is that the ingredients in the formulations can harm the unborn baby. But it’s a misconception! Many safety studies have been done on the effects and absorption of hair dye, and none suggest that coloring while preggers is dangerous or unsafe. But if you’re concerned, definitely have a chat with your doc before booking your next highlights appointment – or try natural colors, like vegetable dyes and henna.
