Calling It: This Is the Most Expensive-Looking Hair Colour Trend of 2026
The "mirror hair" trend is huge news this spring. Here's everything I want you to know.
I'm writing this from my desk in my London flat, and as I look out the window, the sun is finally shining. What seems like months and months of rain might be coming to an end, and I'm ready to embrace all things spring-like, especially when it comes to beauty trends. There's one hair trend in particular that I've spotted all over social media (even the celebs can't get enough), and it feels like the beauty equivalent of that first break of sunshine, when the light is just right, and everything looks glowy and glossy. The trend in question? Mirror hair.
What Is the Mirror Hair Trend?
"The mirror hair trend focuses on achieving smooth, silky hair that is radiant with glass-like shine," explains Bruno Marc Giamattei, senior creative director at Joico EMEA. "When I think of mirror hair, I picture '90s supermodels strutting down the catwalk with their long, lustrous locks flowing behind them—this trend has been a staple in the hairdressing industry for decades!"
I like to think of it as liquid hair, glass hair and glossy hair all coming together to create the shiniest, sleekest and healthiest-looking hair colour you've ever seen. Whilst glass hair was all the rage in 2025, this season sees the trend taken up a notch. In fact, according to Giamattei, this year will see a major focus on hair health, a trend that goes hand in hand with mirror hair. "Each strand [will] shimmer with its natural, eye-catching vibrance, oozing luxury and sophistication at every angle," he says.
