It's no secret that Katy Perry likes to change her hair colour almost as often as she changes clothes.

She's featured pretty much every shade in the rainbow on her head — most recently lavender, for those keeping track — so we're never really taken aback when she debuts a new hue.

Such was not the case last night, though, when K-Pez unveiled her new barnet.

She has, apparently, hopped on the ombré train with not one, but two "normal" colours!!!!

And she wrote on her Instagram pic: "Got dat hair flow back."

Considering we can thank Katy for ushering in the era of colourful hair we're currently living in, does this mean ombré is about to have a renaissance soon?

Just when our hair was all one colour again.
