Hollywood-approved shades of blue hair to try

Want something subtle but striking? Go colourful in a cool-girl way like Sabrina Carpenter by scattering sapphire-hued extensions beneath wavy longer locks.

Before any other A-lister started dabbling in blue, there was Gwen Stefani. This bright blue space buns half-up hairstyle from 1998 is one of her most memorable.

A boldly beautiful hair colour switch is pretty standard for Ciara, but we have to say this neon sapphire shade is one for the books.

This confirms our 'Zoë Kravitz can pull off absolutely anything' theory; she debuted a sapphire blue colour (which may or may not be a wig) in the trailer for her new film KIMI.

Duff may be known for her signature bright blonde, but she was one of the first celebs to make a major shade switch in 2020's initial lockdown, colouring her locks a vibrant aqua blue.

Kylie Jenner has dyed her hair every colour under the sun, but we’re big fans of this icy blue hue. The subtle hints of black work well with her brows, which makes the shade look really flattering on her.

Hailey Bieber rocked an electric blue short hair look (which we’re pretty sure is the work of a wig) for a photo shoot. The look had serious grungy Fifth Element vibes.

As if her neon blue hair colour wasn’t enough to catch your eye, Rita Ora added voluptuous curls to seal the deal.

Billie Eilish became known for her bright blue hair, which is ironic since blue is her least favourite colour. “Here’s what’s annoying: I hate the color blue — it’s my least favorite color. I don’t know how I ended up dying it blue,” she told BuzzFeed.

Lady Gaga is no stranger to outlandish beauty looks, but her 2019 Golden Globes was surprisingly subtle thanks to her decision to style her baby blue hair into an elegant updo.

Remember when Katy Perry had blue hair all the time? While she’s been favouring a platinum blonde look of late, her blue hair days (wig or not) are some of her most iconic.

Dua Lipa took her platinum blonde bob to the next level with a pastel shade dip-dyed through the mid-lengths to ends. We love the cool, undone vibe.

Between the icy silver blue shade, the sharp freshly-cut ends and the collarbone-grazing length, there’s nothing we don’t love about this blue hair look on Kim Kardashian.
