Whether it鈥檚 a cut, a new color or an intricate updo, things are always changing in Celebrity Hair Land (that鈥檚 not a real place, but if it was we think the town center would be filled with solid gold statues of Anna Wintour鈥檚 bob and Jennifer Aniston鈥檚 鈥淩achel鈥 cut). Sometimes the styles shift so quick in Hollywood, it鈥檚 hard to keep up. But that鈥檚 where we come in. While you鈥檝e going through the hustle and bustle of your work week, we鈥檝e been scouering the scene for the coolest moments in celebrity hair. Catch up on all the beauty news you may have missed simply by scrolling down. And yes, Kaley Cuoco鈥檚 eyebrows really are that pink.

1. J.Lo鈥檚 Layery Lob: We love a blunt, shoulder-length cut as much as the next gal, but a layer-less style doesn鈥檛 necessarily work on everyone. So if you鈥檙e looking for a way to chop it all off without ending up with a case of serious triangle hair, you can thank J.Lo for handing you your solution. The performer recently debuted a short, 鈥70s inspired 鈥榙o while on her way to Morocco (you know, as you do on a Tuesday afternoon). (Photo via @jlo)

2. Sienna Miller鈥檚 Throwback Braid: Did Game of Throne鈥檚 Khaleesi and the 鈥90s just have a baby? If they did, it would certainly look a whole lot like the braided hairstyle Sienna Miller sported at Cannes closing ceremony. (Photo via Pascal Le Segretain/Getty)

3. Kaley鈥檚 Pink Eyebrows: This wild new look from Kaley Cuoco might not be a hairstyle per se, but it is definitely hair related. Plus it was such a wow moment, we just couldn鈥檛 bear to leave it out. Over Memorial day weekend, the actress (who was already rocking bubblegum-pink hair) debuted bright pink brows to match her rainbow-colored locks. Way to instantly take things up a notch (or ten), Ms. Cuoco.

4. Melissa McCarthy鈥檚 Subtle Highlights: With June鈥檚 arrival just around the corner, it gives up great joy to tell you that winter is officially over (and has been for awhile). All you dark-haired ladies looking to lighten up for summer, take a hint from the highlighted style Melissa recently rocked at the London premiere for her new movie, Spy. Melissa鈥檚 toffee-toned highlights offer a dynamic element to her espresso-colored locks without going too over the top. (Photo via Chris Jackson/Getty)

5. Zoe Kravitz: Up until Tuesday, Zoe had been rocking her mom鈥檚 (Lisa Bonet) trademark look: a head full of super long braids. But in preparation for the third Divergent film, Zoe traded her long hair for 鈥 wait for it 鈥 a trendy, blunt bob. (Photo via @zoeisabellakravitz)

6. Lady Gaga鈥檚 Beach Blonde 鈥楧o: Sayonara, dark-haired Gaga. The performer documented her whole bleaching process on Instagram late last week and hasn鈥檛 been able to stop taking selfies since. But we can鈥檛 really blame her; the bright new shade is looking all kinds of awesome. (Photo via @ladygaga)

7. Victoria Bonya鈥檚 Faux Bob: If you鈥檙e currently rocking long hair and debating the big chop, here are two things you can do: first, test out John Frieda鈥檚 short hair rule, and second, copy Victoria Bonya鈥檚 faux bob. The Russian model, TV and radio presenter and beauty blogger stepped out on the final red carpet of Cannes rocking the hottest haircut of the moment and then went back to her long locks the next morning.

8. Miley鈥檚 Many Wigs: While Gaga has opted to ditch her endless supply of wigs for that platinum shade of blonde, Miley can鈥檛 seem to get enough of the hair accessory. This week she showed off not one, not two but three different colored wigs. Is she trying to decide whether or not to take a more permanent rainbow-colored hair change? Don鈥檛 tease us, Miley.
