I'm 7 months pregnant and so fed up. Starting to get to the uncomfortable stage and feel like I look a mess no matter how much effort I put in. I think a decent cut and colour would sort me right out but I heard ages ago that you shouldn't dye your hair during pregnancy - although I know many that have. Is this outdated advice or should I wait it out 3 months (or longer if it's frowned upon while breastfeeding) to be on the safe side?
