Rainbow hair has been trending for a while now, and it doesn’t look like it’s going anywhere soon. While we do enjoy the trend, it is quite a commitment. However, Pravana’s new dye gives beauty junkies the option of changing up their hue in an instant. Just like that! Clicks fingers.

Alternatively, if you’re into the rainbow look but want something a little subtle, you could go down the rainbow roots route. That way, your foray into the world of colourful highlights is less obvs but still pretty fun, no?
