Celebrities *brought it* this week when it came to their hair posts on Instagram. Ranging from bold, glam locks (think: Grace Kelly) to straight, sleek tresses made for a modern starlet, these looks did not disappoint. Plus, they provided enough hairstyle inspo to get us through the next week until we do this all over again ;) Check out the fresh, easy-to-copy hairstyles these 11 celebs debuted this week.

gabrielleunionhair

1. Gabrielle Union: Gabrielle鈥檚 hairstyle when she spoke at an AOL event this past week was the epitome of being styled without being overdone. The straight but volumized style that featured two noticeable waves halfway up the front pieces of her hair is a look we鈥檙e thinking of stealing for this Thanksgiving. (Photo via @gabunion)

jeanniemaihair

2. Jeannie Mai: Known for her always-legit hair and makeup, Jeannie Mai rocked an epically cool look this week that blended old Hollywood glam with slightly futuristic and super sparlky makeup 鈥 a really interesting combo that she totally pulled off here (and YOU might just want to pull off this Halloween).

kellyrowlandhair

3. Kelly Rowland: Beauty kween Kelly Rowland looked sophisticated and totally pulled together wearing a super sleek ponytail with a clean middle part. Can鈥檛 go wrong with this look; it never goes out of style whether you鈥檙e rocking it in a tight LBD or comfy jumpsuit. (photo via @kellyrowland)

chrissyteigenhair

4. Chrissy Teigen: Mama-to-be Chrissy (!!) opted for a slicked-back, volumized 鈥榙o at a La Mer party this week. It鈥檚 a great way to make a slinky slip dress feel very now versus totally 鈥90s. (photo via @chrissyteigen)

taylorswifthair

5. Taylor Swift: Vogue Australia鈥檚 cover featured a familiar face with totally different hair 鈥 we almost didn鈥檛 even recognize T. Swift with this look. but we are loving the darker locks on her because her blue eyes stand out. Way to pass up bronde for more substantial yet still subtle hair color shift, Tay.

nicolerichiehair

6. Nicole Richie: Nicole slicked back hair is enough to make you want to chop off your locks. The key here is volume + hold to nail this fancy look. (photo via @nicolerichie)

oliviapalermohair

7. Olivia Palermo: Healthy, shiny and bouncy hair was the name of the game this week for Olivia Palermo. It looks more blonde than usual, but still has that flawless style we associate with OP 鈥 not too styled, not too casual and a good reason for use to reconnect with heat protectant spray + curling irons. (photo via @oliviapalermo)

arianagrandehair

8. Ariana Grande: The Barbie-blonde color Ariana Grande debuted this week was totally shocking and *so* different than what we鈥檙e used to seeing her rock. It still looks awesome, though in her signature high updo. (photo via @arianagrande)

zendayahair

9. Zendaya: The always edgy, always fab Zendaya channeled Grace Jones this week. And. Completely. Killed. It. She looks *amazing* (as always) but really, anyone does when they have as much confidence as she does. People, take note of her fearlessness. (photo via @zendaya)

blakelivelyhair

10. Blake Lively: Looks like Blake鈥檚 long hair is back 鈥 maybe? She鈥檚 either been wearing an insanely real looking short wig on the set of her new movie or she has some awesome extensions in in this photo. But鈥 the real question is, what is she doing in that screenshot that requires her hair to defy gravity?! Can鈥檛 wait to find out. (photo via @blakelively)

ashleytisdalehair

11. Ashley Tisdale: At first glance, we were like, WOAH, Ashley totally chopped off her hair and debuted *two* totally new 鈥榙os this week. But a closer look revealed that she鈥檚 actually just tucking her freshly-dyed red hair into her jacket, giving the illusion of a sleek bob (which looks awesome on her). Take note of this style hack for fall. (photo via @ashleytisdale)
