I Always Thought My Brown Hair Looked Flat—5 Ways I'd Add Chocolate Dimension This Autumn

There's something about that first chill in the air that makes me cross my fingers for autumn. The sight of a singular tawny leaf on the pavement is enough to make my mind stray to the funnel-neck jacket sitting in one of my many open tabs and begin planning my next Gilmore Girls marathon. But as I'm a beauty editor, one question seldom fails to bubble up around this time of year when I catch my flat brown mane in the mirror: Should I go darker with my hair colour?

It's a blanket statement to say that people dye their strands blonder in the summer and deeper in the winter, but it's not inherently false. The sun lightens many people's hair, which presents the perfect opportunity to lean into bright, sun-warmed hues. But as summer heat gives way to a temperate autumn breeze, the attention shifts from golden hues toward rich chocolate, burnished brown, and inky espresso—making everyone wonder if brunettes have more fun.

"Dramatic, cool-toned, deep browns that give a sleek and polished look [are] perfect for the transition of seasons into the colder months," celebrity hairstylist and master colourist Dimitris Giannetos tells me. Fellow celeb hairstylist Marc Ballance agrees, spotlighting environmental changes and increased attention toward hair health as another catalyst. "After a summer of travel, sun exposure, salt water and chlorine, many clients come in saying their hair feels dry and overprocessed," he explains. "Deepening the tone with a rich brunette and adding shine instantly makes the hair look healthier and feel stronger, which is exactly what people are looking for going into autumn."

Between the burnished balayage sported by Anok Yai and the romantic honey-brown bob donned by Hailey Bieber, there's been no shortage of sleek brunette dye jobs on the internet recently. Keep scrolling to see which brunette trends the pros say are worth considering this autumn, from dimensional layers to sleek single shades.

5 Brunette Trends for Autumn 2026

Glacé Chocolate

I'm sorry to be the bearer of bad news, but you're severely out of the loop if you didn't have at least one conversation about Zendaya's flowing chocolate braid at the New York City premiere of Christopher Nolan's The Odyssey—not only because of her impossibly long locks fashioned by celebrity hairstylist Coree Moreno but also because of her supremely shiny brunette strands that flashed caramel in the light.

"I think we're moving into a season where healthy, shiny hair is the biggest trend," muses Ballance. "Rather than lots of high-contrast dimension, we're seeing richer, more polished brunettes that look expensive because of how healthy they appear." Ballance also singles out Zendaya's castmate Anne Hathaway and her uniform iced-chocolate waves: "It's not about obvious highlights anymore; it's about creating a luxurious, shiny finish that makes the hair look incredibly healthy."

Inky Espresso

Brunette is a spectrum of umber shadows and golden streaks, but one of the most alluring shades of brown you can try this autumn is an inky espresso. Giannetos calls the hue "romantic and timeless," spotlighting how fabulous it looks when worn down or pinned up in a chic knot, as shown in this recent look sculpted on Demi Moore.

Whether you're opting for a monochromatic look like Moore's nearly black brunette tresses or playing with contrast like Yai's supermodel balayage (yes, I'm feeling compelled to ask for a chocolate-brown ombré into glossy espresso ombré—no, I won't pull it off like her), it's clear that the darkest browns should be on your radar this autumn. Giannetos recommends enhancing your colour at home with a hair gloss whenever your hair needs a touch-up.

Caramel Glaze

Not all brunettes prefer their strands dark. If you're a blonde searching for a transitional brunette shade for autumn or a deep brunette looking to lighten their hair without losing that autumnal essence, allow me to point you in the direction of Jordyn Woods and Hailey Bieber. Woods has always been hair goals, but her caramel-streaked brown tresses are serving as extra hair inspo as we sidle into the new season. Bieber recently adopted the style as well, leaning into a cool-toned iteration of her dirty blonde with golden face-framing highlights.

Feathery Highlights

If you're craving subtle dimension sans full-on highlights, consider these barely-there streaks I just spied on supermodel Jasmine Tookes. "This is exactly where subtlety makes all the difference," croons Ballance. "Instead of adding lots of brightness, I love the idea of placing just a few delicate highlights while keeping everything within the same shades. Your eye still picks up movement and dimension, but nothing looks obviously lighter."

To channel Tookes's feathery highlights, ask for two to three shades lighter than your natural colour in very small sections. "The result is a brunette that has depth, softness, and shine while still looking completely natural," says Ballance.

Golden Threads

We've talked a lot about minimal-contrast hair colours, but that's not to say that highlights are history. “Highlights based on a person's skin tone will always give hair a lift," says Giannetos. The stylist illustrates how "deep cocoa with golden, feathery highlights" brings beautiful warmth to the deeper hue, while those with neutral tones may favour "a cooler brown." Take, for example, Penélope Cruz's gilded highlights, donned just in time for autumn. I'm certainly sending this snap to my hairstylist.

How to Maintain Brunette Hair Colour

"Healthy hair is always the best hair," says Ballance. To preserve the vitality of your colour, celebrity stylists suggest adding a few new products to your regular rotation. "Use a colour-safe shampoo and conditioner, incorporate a nourishing hair mask once a week, and keep up with regular gloss appointments to maintain richness and shine as the colour fades," Ballance instructs.

If you're not sure where to start, Ballance suggests asking your colourist if there's a specific at-home treatment you can do to supplement your salon treatment between appointments. "The healthier the hair, the more reflective it is, and that's what makes every brunette colour look its best," he concludes.
