Hair dyeing

I didn't dye mine during pregnancy because I was quite paranoid, but a few of my mum friends did and their babies turned out perfectly fine, so I think most doctors say it's okay if you do it in the second or third trimester. If you're worried, might be good to just check with your gynae to be safe, especially since pregnancy hormones can sometimes affect how the dye takes anyway. Just make sure the salon has good ventilation lah.
