The Best Long Hairstyles to Stay on Trend in 2018

Got2b Guardian Angel Gloss Finish Flat Iron Balm, $6 BUY NOW

One of our favorite British beauties, Naomie Harris stunned on the red carpet with loose curls parted to the side, strategically placed to fall gracefully over her right shoulder. This beauty look is timeless, because it's simple to recreate for all occasions — and rather than frizzy waves that hang over her shoulders, Harris' strands are full of body. To achieve incredible shine and ensure a smooth finish, stylist Larry Sims incorporated Got2B's finishing balm into his regimen as a post-blow-dry prep.

Ouai Finishing Cream, $24 BUY NOW

Kendall's best-known for her shiny Rapunzel coif, but for this year's Golden Globes, the model Jenner had Ouai founder and family friend Jen Atkins whip up an undone topknot sitting perfectly centered on top of her gorgeous head. Buns in general can be a bit tricky to design as anything but a hot mess, so if you need a boost, look to Ouai's Finishing Cream for smoothing assistance.

Dove Refresh + Care Volume + Fullness Dry Shampoo, $4 BUY NOW

Hailee Steinfeld went from pitch to actually just perfect since she's been on the music scene, and we were blown away by the entirety of her Golden Globes ensemble. Zeroing in on her beauty look, celebrity stylist Mark Townsend gathered her brunette locks into a contemporary chignon we'd consider pure art. His secret to sustainability is utilizing Dove's dry shampoo by spraying it over hair and bobby pins for extra hold.

Ouai Texturizing Hairspray, $26 BUY NOW

We're getting strong Audrey Hepburn vibes from this fashion designer's posh ponytail during this past London Fashion Week, naturally loving everything about the look. The key to this hairstyle is to add body at the top of the head by bumping and spritzing hair with Theorie's texturizing spray, and balancing out the look with a simple ponytail secured at the nape of the neck, pushed over one shoulder.

Remington C19538 T|Studio Salon Collection Pearl Digital Ceramic Curling Wand , $25 BUY NOW

We're bowing down to the queen whose style is all her own. There aren't many instances where we see Bey with bad hair, and this side pony made of loose spiral curls is very '90s-chic — a trend that worked its way back into fall 2015. For curly Qs that hang low, swap the average iron for Sedu's clipless tool.

Bumble and bumble Thickening Dryspun Finish, $31 BUY NOW

Amber Heard has become one of Hollywood's most seductive icons, so it's no surprise her red-carpet look featured wavy tresses — adding instant sex appeal to her lady-in-red motif. Ideal for a night out with your man or heading out on the town with a few girlfriends, enhance natural curls by applying Bumble and bumble's Curl Conditioning Mousse from roots to ends before letting them air-dry.

Ficcare Mini Maximas Hair Clips, $34 for set of two BUY NOW

To quote Mean Girls, "your hair looks sexy pushed back," and if we can look half as sexy as Sandra Bullock did on The Tonight Show (or, ya know, always), we're taking note of this advice. This particular coif is quick and easy to mimic. Part your hair to one side and secure strands to the scalp with a chic clip.

Style | Lab Prime Style Extender Cream, $15 BUY NOW

There are a lot of prep-and-hold products that go into "effortless" waves. Because Candace Cameron Bure's gentle waves are so soft and delicate, it is important to use a cream or spray that will prolong the style. To assure you've got the beachy bend down pat, prior to styling run Living Proof's Prime Style Extender Cream from the root to ends of the hair.

got2b Mess-Merizing Sculpting Spray, $7 BUY NOW

Judging from our experiences with slept-in braids, there's actually a good chance Blake Lively woke up like this. But just in case those almost too-perfectly-messy strands weren't an accidental 'do, a toss-and-turn braid is simple to emulate. First, gather all hair to one side as if to create a side ponytail. Separate hair into three parts and begin loosely braiding at mid-neck. Secure at the bottom with an elastic to hold. To add texture and organized mess to strands, pull out strands at the top of the head, and generously spritz got2b's sculpting spray all over.

John Frieda Volume & Body Salon Shine 1875 Watt Hair Dryer, $30 BUY NOW

Amanda Seyfried's voluptuous 'do is giving us all the retro glamour feels. Considering the actress prefers to use as little product as possible (according to an interview with The Huffington Post, Seyfried only washes her hair every few days with a spritz of dry shampoo in between), we're recommending the John Frieda Salon Shine hair dryer that includes three different nozzles, so you can control the level of bounce in your blowout.

Living Proof Straight Spray, $17 BUY NOW

Opt for a pin-straight style if your strands fall below your chest. Oftentimes when straightening short hair to an extreme, it loses body. With a longer style like Joan's, there are plenty of stacked pieces that naturally look a bit more voluminous. As far as protecting hair from heat damage and keeping strands straighter for longer, Living Proof's spray is heaven-sent.

Vidal Sassoon Iconic Styling Comb Assortment, $4 BUY NOW

Some mornings, we just can't, but Gigi Hadid's street style 'do makes quite the argument for effortless ponytails being posh. Spritz a bit of dry shampoo around strands and fully embrace bedhead by throwing your hair into a high, centered pony, and give strands a bit more body by teasing the ends with Vidal Sassoon's styling comb.

TRESemme Tres Two Extra Hold Hair Spray, $10 BUY NOW

A severe middle part pairs best with angular features, making Olivia Palermo's square chin and high cheekbones ideal for pulling off this hairstyle. To copy her mid-crease, run a comb through your scalp and evenly divvy up strands. Tightly pull your hair back into a low ponytail that starts at the nape of the neck, and spray your scalp with TRESemme's Extra Hold Hair Spray to smooth fly-aways and keep strands in place.
