Yes, if you do it yourself just make sure that the window is open and if you're going to a hairdresser you could mention that you're expecting just so they know xx

my hairdresser told me it was fine :) she said your hormones can change the colour but if your feeling good and not too hormonal the colour should take really well :) x

Make sure you do a hair test first as your hormones can effect the colour but other than that you should be fine xx

You can yes, just get the ammonia free one! Xx

They can, but the risks are minimal. I'd say you can colour your hair, just wear gloves and open a window :)
