Forget lobs, the new memo circulating Hollywood hair circles is ‘Rainbow hair, don’t care.’

Anna Paquin is the latest celebrity to join the multi-coloured hair squad, dyeing her hair purple, blue and green. After wrapping up the final season of True Blood, the star headed straight to the hairdresser’s to fulfill her dreams of one day becoming a mermaid (a dream she’s had since she was in high school).

If you think you can be persuaded to give rainbow hair, or at least rainbow hair chalk a go, let celebrities like Alexa Chung, Nicole Richie, Rita Ora and Katy Perry (temporarily) talk you into it:
