is it safe to dye your hair in pregnancy? πŸ€”

Hi ladies,
My Obgyn suggested to not dye my hair as she isn't sure which chemicals are the bad ones in pregnancy etc.
I was in my Heath shop today and the chick said this one would be safe. What do you girls think?? πŸ€”
This is my rainbow baby so if there is even a chance it may be unsafe I'd rather roll around with feral hair till November 😊 🌈
