When you think of blue hair, you probably have flashbacks to the super bright box dyes you were desperate to use as a teenager but were never allowed – or was that just us? It’s also the sort of shade that your hairdresser has probably tried to talk you out of at least once in the past.

Fast forward a decade or two, and now you are in full control of your own dyeing decisions, it might still feel like a bold decision, but believe it or not, blue hair is having a real moment. Not only is it extremely cool, but it’s also a whole lot more wearable than it might sound. 

In short, glossed ink hair is being described by hair stylist Larry King, Redken’s UKI ambassador, as a “midnight colour with subtle blue reflect” – and it’s also the reason why the #BlueBlackHair hashtag has 54 million views on TikTok.

The shade itself is one that’ll suit all hair types, but note that’s it’s one best achieved by your colourist who’ll use a toner, like Redken Shades EQ, on a dark brunette base to add extra dimension and depth.

Plus, we love that it’ll make hair so glossy that it’ll look fluid – which also plays into the high-shine trends we’re seeing a lot of recently.

Here, we’ve rounded up some serious inspiration – ranging from more obvious shades of deep, inky blue through to subtle, barely there tones that are only really noticeable when the light hits exactly right.
