Stranger Things [1] fans might recall Millie Bobby Brown's platinum blonde wig in the show's first season. Her new hair colour isn't that. The actress and newly minted beauty brand founder debuted "wheat blonde" hair [2] at her Boots brand launch, and according to a pro, it's the perfect hue to kick off Autumn with.

Miami-based YSV Salon [3] revealed Brown's new hair in an Instagram post. In the duo of photos, Brown is seen with the new colour and a shoulder-length cut — a look that is very different from her previously dark brown hair with blonde highlights.

Colourist Jack Howard [4] of London's Paul Edmonds Salon describes "wheat blonde" as being warm and buttery. "It's an anti-ash blonde, perhaps as a reaction to the mountain of ash tones we've been seeing everywhere," he said. Howard goes on to say that the hue is the easiest one to kick off the new season with, before potentially trying one of the cool platinum hair colours that are often seen in the Winter.
