3 Experts Confirm It: These Are Autumn's Biggest Hair Colour Trends

If there's one thing that everyone seems to want to change in autumn, it's their hair colour. Whilst I've stayed true to my blonde balayage for years now, everyone around me seems desperate to switch up their shade. From deep brunettes to striking copper hues, there are lots of autumnal hair colour trends to choose from, but as a beauty editor, I'm keen to know what new shades are taking over this season. So, I thought it was only right to go straight to the experts.

I asked not one, not two, but three of Hershesons' top hair stylists, and they all weighed in on this autumn's biggest hair colour trends. From classic colours reimagined to striking new hues that will be most requested in salons this season, there are so many stylish hair colours to choose from that it's even convincing me to book an appointment.

6 of the Biggest Autumn Hair Colour Trends 2026

1. Amber-Veiled Blonde

First up, this stunning "amber-veiled" blonde hue. "This is perfect for naturally darker blondes and brunettes," says James Samuel, colourist at Hershesons Belgravia. "[It features] scattered, softly defined pieces of a rich, intense golden shade. This gives a dimensional finish that looks luxe." If you went brighter for summer but want to tone your blonde hair down a little bit for the autumn months, I think this trend is perfect.

2. Toasted Copper

It wouldn't be autumn without a striking copper shade, and toasted copper is the one to watch this season. "[This is] a muted red brown combing depth and rich tone," explains Samuel. "An intentional deep bronze tone that’s subtle and understated."

3. Naked Blonde

Another blonde hair trend I am currently loving is "naked blonde". "[Think] hair that matches your skin: seamless, flattering shades that feel custom-made," says Nicole Kahlani, colourist at Hershesons Fitzrovia. "For textured hair, favour honey blondes and dark caramels—warm, curl‑friendly tones over icy platinum. Deeper/olive skin suits fudge, caramel and burnt terracotta [shades], whilst fair skin looks best in muted, runway‑soft versions."

4. "Greige" Brunette

According to Kahlani, this season, mousy blonde is getting its moment. "Think Mia Goth," she says. "A grey‑metal finish, soft ends and barely‑there dimension. It's perfect for a bleach break — subtle shimmer or a touch of brightness keeps it fresh without going full brunette."

5. Sandy Blonde

"[Sandy blonde] is the perfect seasonal transition for brighter blondes wanting to soften their colour and embrace something a little more dimensional," says Hannah Gayle, colourist at Hershesons Belgravia. "Think sandy, creamy tones with added depth and richness, creating a beautifully lived-in blonde that feels warmer and more luxurious for the colder months."

6. Deep Brunette

Last but not least, let's talk about this deep brunette hue. "It’s no surprise that glossy, richer brunettes are having their moment again," says Gayle. "[This is] the perfect transition into autumn, embracing deeper chocolate and chestnut tones, elevated with beautiful dimension, depth and a luxurious, glass-like shine."
