Is it safe to dye your hair while you're pregnant?

Some of Jenelle Evans' fans don't think so, and they had no problem getting into a heated debate about it after the Teen Mom 2 star—currently preggers with baby #3—posted a pic of her newly-highlighted locks on Instagram, along with a caption thanking her stylist for hooking her up with some "easy low lights and a baby trim!"

The back-and-forth in the comments section started right away.

"I thought you couldn't dye your hair during pregnancy," wrote one follower.

"Ya you can," responded another. "Actually I highlighted my hair during my pregnancy and my daughter is just fine. There's no studies that link to harming baby."

Hmmm. Is that true? I remember being nervous to color my own hair back when I was pregnant, instead suffering through nine months with salt-and-pepper roots. Are you telling me it was all for naught? There seems to be a lot of confusion surrounding the topic. Maybe that's why a bunch of hairstylists then showed up to throw their own two cents into the commenter mix.

"To clear it up I'm a stylist and you should refrain from color in your first trimester," wrote one. "After that it is recommended to use the organics color line but not necessary as long as it's professional hair color."

"I'm a hairstylist as well," added another. "And chemicals don't seep into your scalp, it's completely fine to color your hair while pregnant!"

These guys make a pretty good case. Still, Jenelle's haters remained skeptical.

"A hairstylist giving out medical advice like she's been through med school," mocked one. "Give me a break."

So what's the deal? Can we go ahead and get our hair did while we're expecting or not?

Sorry haters...but studies have, in fact, shown that coloring your hair while pregnant is A-Ok, since so little dye is absorbed into your scalp. If you want to be extra safe, though, you should probably consider switching to temporary color, which is less toxic than permanent.
