i've googled this curly q all over and got conflicting answers. all i can say is what a hairdresser classmate of mine is doing - not doing her hair as she is pg with her miracle bub - she's happy to just put up with regrowth. as am i, despite my greys! i'm just thinking less chemical load on the system has got to be good

in the end, you gotta do what you personally think is best.
