Hair, hair, hair!!!!

Ive read loads about hair dye and it being completely fine during pregnancy so have booked in a salon for my 21st birthday for a hair cut and colour(100% needed, to feel pretty😂👍) but the hairdresser said we need to bleach it first...shes aware im pregnant and said its fine to use bleach. Online doesnt say much on bleach just hair dye in general.

Anyone bleached there hair while pregnant ill be 30+ weeks. How did it turn out or would you not do it just to be safe?

Thank yous👍💗💙
