Hair dye?

[Baconbuttie88]

I am currently very early in to my pregnancy at 4 weeks, what are the do's and don't when it comes to hair colouring?

I only tend to get my roots done (my greys covered) dark every 6 weeks and balayage every 4-6 months.

I have read a lot of things recently saying that it is totally fine to get hair coloured. I read this book that goes into detail on the science of why it's OK, the NHS guidance also says it's OK, in fact I've not read much that says it isn't. The danger is really only if you are using very harsh chemicals in a badly ventilated environment.

Having said all that, I waited until past 1st trimester and then got only semi-permanent colour done as its less extreme chemicals.
