Whilst many of Kourtney's 139 million followers loved the look, even comparing her to Ariel from The Little Mermaid, others were concerned she was too young for the transformation.

"Why ruin your kid's hair?" asked one, whilst a second added: "So pretty, but I hope it's the temporary spray. She has a beautiful hair already."

Another follower of the star, who happens to be a hairdresser was quick to defend the 42-year-old's decision.

"Trust me, her hair is not ruined! I'm sure it's temporary color, even if it's not she has the money to pay for professional products to keep the keratin and moisture in her hair. No worries, I'm sure it will survive," they wrote.

Prior to getting her new look, Penelope spent quality time with her dad Scott Disick.

Just last week, the proud dad-of-three, who also shares sons Mason, 11, and Reign, 6, with the eldest of the Kardashians, posted a picture showing his daughter helping out in the kitchen.

"I wear my sunglasses at night So I can, so I can. CHOP ONIONS," he captioned a photo of Penelope wearing sunglasses whilst posing next to a red onion.
