dye hair?

Yes you can! There is no evidence that this affects breastfeeding! Only that baby might not like the smell :) https://sg.theasianparent.com/dye-hair-while-breastfeeding/?utm_source=search&utm_medium=app

Best to ask your doctor, they have high education for a reason. I dyed my hair during pregnancy and after pregnancy, my doctor let me. so it depends on your doc..

You can, but not recommended. Maybe search for an organic dye?

Not encourage to do so even with organic product hair dye.
