As hot (and hopefully vaccinated) girl summer approaches, you may want to start thinking about ways to cool off a little, and there's no better way to do it than with your hair [1]. Sure, you can go platinum blonde, amethyst brown [2], or even white, but if you want to do something bolder, that's where the "icy blue" hair-colour trend steps in.

"As we find ourselves emerging from a stressful and not-so-exciting winter, expect to see more and more people leaning into an icy hue to welcome the warmer weather," Nick Stenson [3], Matrix artistic director, told POPSUGAR. "Icy blue shouldn't be mistaken for pastel blue; it will be more electric with a little more depth, which is great for colour longevity."

Dyeing your hair a fun colour [4] like this vibrant shade of blue is a guaranteed way to turn heads. Unlike those times growing up when you'd smear temporary hair dye onto your ends in your parents' bathroom, enlisting the help of a professional to get the ice-blue shade just right will elevate the look and give it an effortlessly cool vibe.

"You'll likely be seeing a lot of icy-blue hair in your time spent scrolling on Instagram or TikTok this spring," Stenson said.

If you want real-life examples of the icy-blue hair-colour trend in action, look no further than Megan Thee Stallion, Kylie Jenner, Hilary Duff [5], and more ahead.
