Whilst I’ve been known to dabble in various hair colour trends over the years, from balayage to highlights, I’m a brunette gal through and through. I don’t think I’ll ever fully stray from my natural colour, but that doesn’t mean I don’t want to switch it up subtly for the summer months. That’s where the experts come in.
I was keen to know what the biggest summer hair trends for brunettes would be, so I reached out to Christel Barron-Hough, award-winning colourist, founder and creative director of STIL Salon, to ask which brunette looks we can expect to see this season.
Below, you’ll find so many stylish recommendations, whether you want to make a small change or go for something dramatically different. I don’t know about you, but all of these trends scream summer to me, and I can’t wait to show my hairdresser and give one a go myself.
4 Biggest Summer Hair Trends for Brunettes
1. In-Between Brown

Possibly my favourite hair colour trend of the season, say hello to ‘In-Between Brown’. “This is an updated version of sun-kissed brown as it’s the perfect in-between brown, with naturally lightened ends,” explains Barron-Hough. “It can be tailored to suit both warm and cool complexions as the tones can be dialled up or down. We love hand-painting the lighter strands with a high-lift colour and glossing the roots and ends in between with a semi-permanent hair colour.”

Yep, even the celebs are fans. How incredible does Camila Morrone’s hair look here?

Speaking of shine, this in-shower treatment will add a shiny finish whilst maintaining colour intensity.
2. Spiced Brunette

If you want to change things up a little bit, you can’t go wrong with spiced brunette. “This colour trend is filled with a lot of energy and warm hues, such as gold and red,” Barron-Hough tells me. “We love this colour as an all-over gloss for ultimate high-shine quality.”

Daisy Edgar-Jones recently debuted her new, spiced brunette hair at the Saint Laurent Menswear Spring/Summer 2027 show at Paris Fashion Week, and it’s safe to say I’m obsessed.

3. Deep Summer Brunette

Fancy something with a little more depth? Deep summer brunette is giving me all the quiet luxury vibes. “[This trend] is all about drama and mystery,” says Barron-Hough. “It’s somewhere in between dark brown and pure black. This is great as a semi-colour choice as it will add lots of depth and gloss to the hair. We [also]love it with a bob as it looks super chic.”

There’s no denying how chic this hair trend looks in the summer months.

I’m yet to find a hair oil that delivers a glossy effect quite like this one.
4. Sweet Like Chocolate

Last but not least, this stylish, chocolatey brown hue. “This is the ultimate brown hair celeb trend worn by Peggy Gou, Kendall Jenner, Dua Lipa and many more,” says Barron-Hough. “It’s all about enhancing the natural hair colour with lots of depth and bringing out warmer hues such as brunettes and gold.”

To get the look, Barron-Hough says to layer different hues and brunette levels, making it look natural but full of energy. “It can also be tailor-made to suit warm or cool complexions by adding more warmth, or subduing the brunette hues for a more opaque appearance,” she tells me.
