Blame it on the weather, blame it on Billie Eilish, but literally everyone's after blue hair right now—from subtle pastel ombre tones to dark black midnight hues.
Interested to try it? Picking the perfect shade of blue (which, ICYDK, is Pantone's color of the year for 2020!) for you depends on three very important factors.
First: What color do you already have? If you're super blonde, you've got the pick of the bunch, from baby blue washes to deep navy. But if you're any darker than a number seven (aka dark blonde), going blue might require that your hair is lightened to do justice to those azure hues.
Second: Work out what kind of blue hair you’re going for. All-over cyan? Blonde ombre? Sneaky chunks of navy that peep through when your hair is curled?
Third: Think of the maintenance. Blue hair color fades pretty quickly to a greenish haze, so sulfate-free hair care is a must to avoid stripping during washes. You’ll need touch-up appointments at least every two months, preferably more (unless you’re DIY-ing things).
Speaking of DIY-ing, topping up on your overall blue shade with toners is easy enough, but if you're contending with dark root regrowth that requires lightening, it’s worth sticking to the professionals, as pricey as this might be.
Our advice is to find inspo pictures of everything you’re keen on but talk to your colorist about what realistically matches your skin tone, your touch-up budget, and your maintenance levels. Or, be like Billie and embrace the grungy roots (your bank balance—and your scalp—will thank you).

What's cooler than a statement color? A statement color and a badass crop, obviously.
