TikTok has taught us so many things when it comes to beauty hacks – from curling our hair with a dressing gown tie to the quickest ways to nail winged liner.
Every week another nifty trick pops up on the platform, often saving us time and money – and helping us understand the beauty world a little more.
The latest one is all about the humble hairbrush.
And it could provide some much-needed answers, like why hair can get greasy even after washing?
TikTok creator @everything_tidy decided to investigate how much dirt hairbrushes have on them.
In her clip, she explains that she heard from a woman on TikTok that hair can get greasy or oily quickly not only because of hair follicles, but due to the dirtiness of a hairbrush.
She says: ‘So I’m gonna put that to the test. I’ve put all my brushes in the sink and we’re gonna leave them for a bit. I’ve used hot water and shampoo because she [the online woman] didn’t state what she used – I figured because it’s hair.’
