It’s a shade that sits under the same umbrella as ‘expensive brunette’ in that it’s luxe and has lots of multi-tonal dimensions. “It’s a great way of upgrading brown hair for winter or to make the most of any leftover lightness from summer or it can be a great option for those who are mostly dark-haired but are starting to see natural grey hairs making their way in,” says Smith.

“By adding lightness and dimension to the hair, while not necessarily covering the greys, draws the focus away from them, making it an ideal choice for anybody wishing to work in harmony with their changing hair colour rather than fighting against it.”

Beurre brunette is ideal for darker to mid-brown bases, and Smith says that your colourist should weave buttery, golden ribbons into the hair in fine pieces, ensuring they’re lighter around the sides of the face and gradually disappear as they get closer to the root.
