I am a cosmetolgist. And I do color all the time andall my children are fine. The only thing to consider is because of your hormones being different the results could be altered. Proffesional hair color will not harm you or your unborn baby :)
I've always heard it's fine after 12 weeks.
AMMONIA FREE! only Ammonia Free (: and bleaching you CAN do, but i just say nahhh
Thanks!(: but ha, ummm my hair.
your hair or the baby's hair?? you said 18months...just checking
You can color just don't make a habit of it and make sure you are in a ventilated area or outside
Colour fine not bleech as chemicals in it
