And the latest star to join the rainbow hair club is ... Lena Dunham! In need of a change, the Girls star traded in her platinum locks for something even bolder: a vibrant shade of green. She rocked the "newly minted" look while promoting her book, Not That Kind of Girl, in Toronto on Thursday, where she amped up the edge factor even further with a motorcycle jacket and winged-out liner. Though she’s no stranger to dramatic hair changes (she debuted a bowl cut right after wrapping up the hit show’s fourth season), this is certainly the most daring shade we’ve seen on her yet!
But Dunham isn’t the only celebrity to test out the hot hair trend as of late: Kate Hudson and her mother Goldie Hawn supported breast cancer awareness with a beautifully pink makeover earlier this week. Inspired to take the plunge?
