It's no secret that Kim Kardashian loves a good hair change or two. From blonde to brunette and even to pink, her hair is always styled to perfection.
But recently, Kardashian revealed what her real hair actually looks like.
The playful video sees the mother and daughter lip-synch to the Christmas classic 'Baby, It's Cold Outside' before wishing their fans a happy Christmas Eve.
The video begins by featuring Kim on a bed sporting her natural hair before it cuts to North, who dramatically does her best interpretation of it being cold outside.
Now, as a fashion icon, Kim often has the world's best stylists with the tricks and tools of their trade to hand to keep her hair looking fabulous.
As we've seen recently, she's been bleaching her natural dark hair, and if this TikTok is anything to go by, it seems that all those chemicals might have taken their toll.
This comes after Kim bleached her hair for the Met Gala, where she wore the dress of arguably the world's most famous blonde, Marilyn Monroe.
She went on to reveal in an episode of The Kardashians that it was no mean feat getting her dark hair the same shade of platinum blonde as Marilyn's.
In fact, it took a whopping 14 hours to achieve the look, which she debuted at the event.
Kim later told Vogue: "I did want a physical change.
"So I thought I would wait and do it for this, so I’m spending a day straight dyeing my hair — 14 hours straight! — to get it done.”
However, it seems like it's just as tough to maintain the colour as well, as Kim mentioned on Live With Kelly and Ryan that it takes 'so much work'.
As reported by Glamour Magazine, Dylan Brittain, the artistic director at Rainbow Room International, said: "This hair colour trend looks incredibly expensive and costly.
"It requires monthly or bi-monthly trips to the salon due to the root regrowth and to keep the colour looking as fresh as possible."
The TikTok came from Kim and North's shared account and the mum of four recently explained that her daughter's access to the social media platform is very much limited.
She told Gwyneth Paltrow on her GOOP podcast that North can only get TikTok 'on my phone' and 'we don't do comments'.
Kim added: "It's not something where she can scroll and look at things."
