In the slay-or-be-slayed world of celebrity beauty, a simple haircut can make or break your career (let鈥檚 all observe a moment of silence for Felicity鈥檚 curls). Thankfully, Halloween brings us an extra-special dose of trick-or-treat magic, when we can throw out the rules and simply let chaos reign. And with all the Halloween聽dramz still fresh in the air, we spied a number of newsworthy tidbits, ranging from stars with fresh new shag聽haircuts to actual celeb-led聽treasure hunts! As always, there was no shortage of hairspiration to be had, whether it鈥檚 the fun All Hallow鈥檚 Eve hues we saw on Cindy Crawford or the messy-pretty look of the popular knotted ponytail. Take a look at these next 12 finds and see for yourself what happens when Hollywood gets ready for Halloween.

1. Cindy Crawford: Let鈥檚 start things off with a bang (or blowout) courtesy of legendary model Cindy Crawford in an ultra-rare selfie, giving us a peek of her candy corn-hued hair. We never took this fashion icon for the Halloween-loving type, but knowing she鈥檚 festive at heart makes us love her even more.

2. Naomi Campbell: Naomi is another iconic beauty, known for her amazingly long locks and killer style. She really brought the glam factor this week, completing this sparkly costume with a sexy updo and romantic flowers in her hair.

3. Elsa Hosk: Um, rumor has it that this Swedish beauty could鈥檝e been the inspo for Frozen鈥榮 Elsa 鈥 and we totally see why. After a few glances at her gorg Insta fed, we were totally convinced. That pretty messy bun with those face-framing strands all but announces to the world that she鈥檚 here to slay 鈥 oh, sorry, we totally meant stay.

4. Katy Perry: YAASSS! The playful pop star Katy Perry brings on the giggles in this primping-selfie featuring a ridiculous beehive wig. It feels like forever since she graced us with an Instagram selfie, and we鈥檙e super happy that she did!

Never stop working for it. 馃槈

5. Christina Milian: After being spotted with her ex Nick Cannon (arousing our suspicions of a possible reconciliation), Christina stopped us in our gossipy tracks when she debuted this jaw-dropping selfie. We know, we know 鈥 metallics are in, but in case you didn鈥檛 notice, that wig鈥檚 made of actual metal! Talk about taking industrial chic to the next level.

6. Shay Mitchell: Shay Mitchell鈥檚 haute and she knows it. Flaunting what must be her sexiest look ever, she totally helped us get past all the phases of our PLL-mourning.

7. Chloe Grace Moretz: OMG, is the pouf making a comeback? Chloe is one of our fave Hollywood hair icons, and she鈥檚 not the first celeb we spotted with this gravity-defying 鈥榙o. Only time will tell, so keep your eyes peeled (and we will too).

8. Ashlee Simpson: Jessica WHO? Ashlee鈥檚 far from living in her big sister鈥檚 shadow, and here she is looking festive and WOW-worthy to prove it. She鈥檚 pictured along with her aww-dorable family, and we鈥檙e super impressed by her bold and ginormous blonde wig.

9. Ashley Benson: The ending of PLL turns out to have been the very best thing to happen to celebrity hair in recent history. Along with Shay, her former PLL co-star Ashley absolutely killed it this week with a newly cropped lob. We lost it over those pretty messy waves and platinum tips.

Wonder what she was thinking back there...

10. Nicki Minaj: Nicki looks tres chic rocking long, smoothed-out tresses. This look gets our vote for her new signature style. It鈥檚 not often that we see her without a trendy or colorful 鈥榙o, and what a treat it is when we see her go glam.

11. Kylie Jenner: Yes, she鈥檚 back on our weekly hair radar, but she totally deserves it thanks to her Christina Aguilera Halloween costume that rocked our world. Not only did she revive Xtina鈥檚 Dirrty-era look, but the queen of all things trendy even got Xtina鈥檚 hard-earned stamp of approval. Way to go, Kylie!

12. Rosie Huntington-Whiteley: After Kylie鈥檚 dirrrty display, let鈥檚 end on a refreshingly classy note with a look so jaw-dropping, it transcends all trends. Rosie proves that perfection never gets old. Her long down 鈥榙o features an elegant side part, with her strands blown out to shiny perfection. #Goals.
