Just like Julia Fox, I'd like to think of myself as my own muse. I mean, you've gotta back yourself, right? But in all honesty, when it comes to Hailey Bieber and her many – shall we say – #lewks, there's no doubt that a little a lot of beauty inspiration has been drawn. After all, she is the CEO of glazed doughnut nails, aka everyone's favourite summer mani. But alas, with a new season change a new HB trend has arrived and this time we're stepping into new territory: the hair. So, if you're looking for a slight autumn refresh, look no further than to the model's new shade.
In an Instagram post uploaded by Hailey's very own hair colourist, Matt Rez shared that recently, the model decided to go "a lil richer for fall 🍁🍫🤎". Now to give some context, by all means, Hailey's hair was not drastically different prior to her new colour – we're talking a true brunette. However, after seeing the pictures shared, we can totally see that the new tone is much richer. Think: milk to dark chocolate.
To give us a little more detail behind the new colour, Matt wrote that he used " = parts of #redkenshadeseqbonderinside 07NCH + 08GG + 09GB to get the richer color". Now, this may sound a lot like gibberish to most of us (or perhaps it's just me?) but show this to a trained hair colourist and I'm sure they'll know what to do.
Oh, and it's not just Hailey who has opted for a darker look, for in recent weeks, Kristen Stewart and Lily James have, too, dyed their hair for autumn. And of course, to no one's surprise, they're proving that it's very much a vibe!
Don't mind me while I contemplate my next hair transformation...
