After you reach second trimester, you can dye your hair. Just no bleaching! Also, make sure its ammonia free.

Doing mine right now. lol. I just made sure to do it after 12 weeks.

Yes I have been getting highlights since about 16 weeks, like people said make sure it's well ventilated

I've dyed mine about twice already. I had all the windows opened and had the vents and fans going while I did it

Yes just make sure its a well ventilated area and have a professional do it

yes

I used ammonia free dye, and dyed my hair 4 times while I was pregnant, healthy pregnancy, delivery and baby(:

yes but I would not use bleach

yep! just make sure there is plenty of ventilation.
