Hailey Bieber's new colour is called "cinnamon cookie butter"

Check. It. Out.

Hailey Bieber's new warm toned brunette look is making waves on social media, after her Stylist, Matt Rez, posted a super cute video of her on his Instagram, post-salon visit.

The colour is being labelled "Cinnamon Cookie Butter".

It's throwing warm brunette vibes, and is another shade of chestnut brown with a touch of copper.

Hailey has certainly set her fair share of hair and beauty trends over the last year.

Between the glazed doughnut nails and her "extreme" blunt bob cut earlier this year, the style queen seems to be able to do no wrong.
