Pregnant and hair dye

Hannah • Pregnant with #2 - baby GIRL- EDD 8th October 2017. Already have little boy who is 2 1/2yrs
Ladies I need your advice. My roots are getting so bad but I've read that you shouldn't due your hair in the first trimester. I'm 8weeks3days and I'm going to have to start coming to work with a bag on my head. I'm trying to keep my pregnancy from work till 13 weeks but with my bad skin, sickly face and now bad hair- I'm worried they might click on. Help? X
