North America's latest obsession with the Danish concept of hygge has officially extended far beyond just lighting the fireplace and cozying up with a warm mug of tea. 

The Nordic ritual of enjoying life's simple pleasures now includes how you colour your hair. It's going to be this years' biggest trend, and you're in luck, because it suits EVERYONE.

Known as 'hygge hair', the colour is all about warmth and comfort, with soft coppers, rich browns, buttery blonds, and creamy oranges poised to take the hair world by storm.

If you're still unsure what the 'hygge' trend is, the official definition - thanks to Oxford Dictionaries - is "a quality of cosiness and comfortable conviviality that engenders a feeling of contentment or well-being."

If you're wondering how that translates to hair, well, it's complicated. The trend is less one specific shade, and more of an overall concept. Think of the warmest, coziest hair colour ever, and that's hygge hair: auburn, chocolate brown, deep cherry and golden blonde. It's a trend literally anyone can rock with utmost ease.

One technique to achieve ultimate hygge hair is ombre. Gradually fading into colours like caramel blonde, rich brown and toffee blonde gives the hair a warm, naturally sun-kissed look. Another is balayage: ombre low-key sister.

Basically, if you stay away from platinum blondes and dark-as-night blacks and opt for a warm hue, your hair colour is hygge. Simple, right?

And considering winter is one of the best seasons to experiment with warm, cozy colours, the time is now to go hygge. Just remember to wear cozy socks, light the fireplace and cuddle up with a warm mug of tea afterwards to complete the look.
