It’s been an exceptionally busy week for celebrity hair makeovers. (Justin Bieber’s cut. Candace Cameron Bure’s chop. Hilary Duff’s gray color.) And believe it or not, there are even more hair happenings to add to the list, for those keeping tabs.

First up is Lily Allen’s totally bold hue. She stepped out this week showing off a highlighter green shade with light pink ends, styled in a topknot with side swept bangs. (Style snaps for matching her hair to her accessories.)

She first debuted the switch on Instagram last week captioning the photo, “Not long till I’m 30, one last hurrah on the hair front. ????? watermelon hurr dun care. @alexbrownsell #funkytintlives?” The singer turns 30 on May 2, and we’re curious if she’ll actually return to a normal shade. (She’s the master of quick neon changes and has basically tried the entire rainbow.)

It’s becoming an end-of-the-week norm to check in on Kylie Jenner’s hair. The last two weeks brought us long blue, short pink and braided gray and now she’s heading into the weekend with a long, dark mane. She celebrated the Opening Ceremony and Calvin Klein’s launch of the #mycalvins Denim Series in L.A. with sisters Kendall Jenner, Khloé Kardashian and Kourtney Kardashian wearing jet black extensions. She even posted another snap Friday afternoon showcasing the long strands, courtesy of go-to Kardashian/Jenner stylist Jen Atkin.

And finally, Jamie Chung also showed some “long hair, don’t care” Instagram love on Thursday, styling her new locks in a low pony with lose waves. Seeing as Chung’s always one step ahead of the trends, some editors are totally rethinking our “short hair for summer” plan.
