8 Celebrities Who Flawlessly Rocked Navy Blue Hair

Over at Byrdie, we live for women who aren't afraid to experiment with daring hair colors. There's something so unapologetically gorgeous about walking into a room with a bold hair color that others can't help but compliment. I admire women who have that kind of confidence so much that I even made it a part of my New Year's resolutions last year to experiment more with my hair. Oh, to be a hair unicorn! What a fun life to live. 

The hue we're digging at the moment is navy blue. There's just something so undeniably cool (literally and figuratively) about midnight blue hair. If you don't want to go all the way with permanent color, try Splat Hair Chalk ($6) in its navy blue shade. This temporary hair color glides on your hair so easily, leaving a major color payoff.

But if you're going all the way, expert celebrity colorist Michael Casey of Eliut Salon shared his most important tip when it comes to dyeing your hair a bold color like blue: "If you want pastel, green, or blue hues, you need to pre-lighten your hair to a very pale blonde first and then deposit the color. These colors fade very fast, so you will need to spend a lot of time refreshing the bright colors," explains Casey. In other words, make sure you're ready for this commitment. 

Some of our favorite It girls in Hollywood have worn iterations of this wavy, cobalt shade and we rounded up the prettiest styles. Let these gorgeous indigo shades convince you to go blue.

Katy Perry, also an infamous hair unicorn, obviously has a thing for blue. Perry's longtime colorist, Justin Anderson, has nailed just about every shade imaginable for the singer. This color chameleon walked the 2012 MTV Movie Awards in a playful blue wig accompanied by the sharpest cat eye.

We're in love with the ombré approach Jaime King took with her mermaid hair back in 2012 at the Saint Vintages Love Tour Cancer event in Los Angeles. From baby blue fading to deep purple, this daring hair looks so good on her. The actress filled Byrdie in on this dye job: "I’ve always wanted to dye my hair a different color but I couldn’t because of contracts, so when I wrapped the first season of Hart of Dixie I just said, ‘Let’s do it.’ My husband and I went to the drugstore and bought purple and blue dye. My husband always colors my hair for me. He’s a director, but he’s also a painter, so I go to Tracey Cunningham, she mixes my color, and then Kyle paints it on. He painted this on at home one night.”

We've seen Rita Ora wear it all—so she obviously didn't discriminate against blue. The singer took a step on the wild side when she posted this Instagram picture captioned: "Today it's smurf day #rehearsals #album2 #bluehairday". Of course, it wasn't too long until she was seen wearing another shade of the rainbow on her hair, but we're here for this Instagram moment.

We call it dip-dyed breakup hair, and we'll never be able to get over this look from 2015. She paired her cobalt locks with jet black and platinum blonde, and it's literally everything.
