Kourtney's five-year-old daughter Penelope was photographed sporting a new pinkish-purple hued hair style while leaving an LA art class with her mum and older brother, Mason.
The mum-of-three didn't share whether the colour was permanent dye or if it was temporary colouring, but the Daily Mail reported that it appeared to be a temporary hair chalk.
No matter what the hair colouring was, mum's of the internet were NOT having it, and couldn't help but leave their unhappy commentary.
One wrote, 'Hopefully it's the wash out type kid dye.'
While another simply added, 'Don't dye your kids hair.'
'I really hope that is fake hair dye on that little girl,' someone commented.
This is not the first time that Kourtney's parenting decisions have caused controversy.
This year alone she was slammed on social media for posting a photo of her kids sitting on the hood of her car, as well as a picture of Penelope wearing a clip-on lip ring.
What do you think? How old should a kid be before they dye their hair?
