In the clip, Kim, 42, can be seen sitting on her bed in her pyjamas sporting a fresh-faced no make-up look.

But what captured fans’ attentions was her short tresses, which looked very different from usual.

The reality star’s real hair – without extensions, wigs or styling – looked much thinner and drier than normal.

Big difference: Her wet hair looked to be slightly damaged from multiple dye-jobs and a far cry from her natural glossy raven locks.

Kim Kardashian and North goof around on TikTok pulling funny faces

The nine-year-old’s following has rapidly exploded on the platform, but to protect her little girl from the dangers of social media, the reality TV star has put a number of rules in place.

Kim recently sat down with Gwyneth Paltrow on her GOOP podcast and shared that North does not have free reign over the account.

For one, Kim stated that the TikTok app can ‘only be on my phone’ as to prevent North from potentially coming across an inappropriate or harmful post.

‘It’s not something where she can scroll and look at things,’ The Kardashians star explained, adding: ‘We don’t do comments.’
