This fall and winter, the classic brunette comes with a precious glow. Enter: “molten brunette”—a deep, shimmering shade that looks expensive and luxurious. Already adopted by celebrities and it-girls alike in anticipation of the falling temperatures, this brunette 2.0 feels both red carpet-ready and a soon-to-be-hit among the street style set. So far in 2025, we’ve seen hair trends span cherry cola to ginger spice, mocha mousse, and vibrant copper—molten brunette is just the next one you need to know for your next sit in the salon chair.

What is the molten brunette hair color trend?

Brunettes have been having a whole lot of fun this year, from toffee shades to mocha and taupe. Fall and winter is calling for something just as bold and elevated, but with a minimalist spirit.

“Molten brunette” is a shade of brown that evokes the heat of molten metal, creating a sumptuous glow for your hairdo. Neither solid brown or a deep caramel, this color marries chocolate, amber, and mocha tones to give the impression of light flowing between strands. The result: hair with a liquid, almost iridescent shine.

The trick to that molten brunette glow is how subtly multi-dimensional it is. The dark brown is not an austere, uniform shade, but a deep and warming sweep of dark color that catches the winter light, whether your hair is straight, wavy, or color. What it achieves: a color that feels discreet yet sophisticated, and denotes much-needed warmth through cold and winter thanks to its almost liquid sheen.
