You can after the first trimester but please avoid hair dye that has ammonia. Not many left out there that have it but there are some so be careful when picking. It will say right on the box if it has it or not.
I just dye my hair red without any problem they say to stay away with bleaching hair but any dye you can use is not bad
@babylon1, yes you can as long as is a well ventilated area and you don't leave it on for longer that it's supposed to be on.
My midwife said after the first trimester and to not touch the roots too much
After first trimester is best and you can use any hair bye btw u just have to be where air is circulating. Outside is best
I did highlights few weeks ago. It was so embarrassing experience. I got so hot in there, so I felt I gone pass out and then I throw up all over their bathroom floor, because the smell made me so sick. If you can deal, with the smell you're fine.
