Hair dye ?

Hailie • 🎀20 years old, pregnant with my baby girl. February 18th 2016! ❤️
Ive already died my hair once already and its just black hair dye... But my black is all gone and my hair looks gross... I want to dye my hair again, but i dont because i know the chemicals and my baby comes first...
I also got my nails done as well but i made sure that the products that they used were safe and i wore a face mask because i didnt want to breath in the acrylic nail stuff... 
What is everyones opinion on hair dying ?
I would never bleach my hair while pregnant though.
