Hair dye in pregnancy

I’ve not box dyed it but I had highlights done this week and it was fine, my hairdresser just advised me to have another patch test beforehand as apparently you can develop allergies in pregnancy! X

I did! I waited until 2nd trimester. I went to a professional. It went well.

I continued to use box dye whilst pregnant, I was just a bit more careful than usual about keeping the room well-ventilated and I went slightly longer between colourings to minimise exposure https://www.nhs.uk/start-for-life/pregnancy/using-hair-dye-in-pregnancy-is-it-safe/#:~:text=Most%20research%20shows%20that%20it's,low%20amounts%20of%20these%20chemicals.

Get a patch test just in case. I've just had my hair dyed the other day at a hairdressers

Yes it’s safe

Yes I’ve dyed and coloured my hair red during the end of my second trimester
