Blake Lively is known for her shiny, thick blonde hair. But this week, the actress showed up at the American Made Summit with a few inches of brown roots. Is the two-tone look a fashion statement?

Probably not. Lively and her husband Ryan Reynolds are expecting their first child next year. “Blake Lively is probably very cautious about chemicals that go on her body,” says Dana Ionato, a sought-after colorist at Sally Hershberger Downtown. While she stresses that the decision to dye (or not) is up to the client, she adds that there is no real evidence that hair dye can harm a fetus – a notion that Mayo Clinic also back. “Doctors always recommend being extra cautious in the first trimester,” she says. “But after that, you’ll be fine.”

Still, Ionato has a few recommendations for pregnant women who decide to color their hair. First, she says highlights are the best choice for someone who has visible hair regrowth, like Lively.”“As long as she’s not filming and can take a break from coloring, highlights are all she needs,” says Ionato. “They are considered an ‘off-scalp’ application that never reaches the scalp and penetrates it or enters the bloodstream.”

Ionato also recommends using an ammonia-free formula if you’re pregnant, but that’s not the only ingredient to look out for. “There are many permanent colors that are ammonia-free or ‘organic,'” she says. “But be careful and look out for these ingredients: p-phenylenediamine, dihydroxybenzene and aminophenol. They replace ammonia, but they’re still harsh chemicals.” Read home dye labels carefully or ask your colorist what he or she recommends.

Finally, Ionato says that pregnant women who want to take a break from coloring should not stress. “I mean, it’s only nine months and it Isyour child, so I always respect the client’s wishes,” she says.I’m sure Blake hates her roots, but for most women, the baby comes first.”
