RE: Can I get highlights? (nm)
Hi! I'm 10 weeks pregnant and I just had my hair colored. Not just highlighted, but fully-colored. I checked with my doctor, and she said that the ACOG (American College of Obstetricians and Gynecologists) has declared it acceptable and she also feels its fine. I also did some searching on the web, and did find the ACOG site (sorry, don't remember the address) and they did indeed say that it was fine and posed no known health risks.
That being said, I'd still check with your doctor to see what he/she says. I'm just telling you what my doc said!
Good luck!
