You can dye your hair. They have the ammonia free dyes too. The reason they say to wait to dye your hair is because of the hormones in your body could make the hair dye do weird things to your hair. For me, I didn't know I was pregnant, I got my hair dyed and when I washed it for the first time ALL of the dye washed out, due to my hormones, the dye didn't stick. Some women have reported that the dye caused a color that they were not looking to get and for some there's no abnormal effect. But, it would be worth at least using the ammonia-free hair dyes, even after the first trimester.
