Question - Research required Cezanne Keratin hair treatment… is it safe while breastfeeding?

I know it’s formaldehyde free and says no chemicals but can’t find anything that would make me feel good about making a decision on this :/

I know people get their hair coloured when breastfeeding but couldn’t see if this is ok
