If "Jennifer Lawrence Hair" were a college major, we would graduate with a 4.0. Sure, we could spend years of our lives studying her nuanced on-screen performances or her boundary-breaking feminist viewpoints, but what really intrigues us is her vast repertoire of hairstyles. (Don't freak -- we're 99 percent kidding.)

Really, though, we continue to be impressed with JLaw's heightened beauty game, nearly as much as we are with acting chops and off-screen charm. (After all, they don't just give Dior campaigns to anyone).

Perhaps the feature for which Lawrence has become best known in the beauty world is her hair. Over the years, she's pulled off an extensive range of looks, from long, voluminous brunette locks to cropped blonde pixies. We've loved some looks more than others, but what never fails to inspire us is the confidence she brings to each one.

So, before the actress debuts her latest style at this year's Academy Awards, we decided to honor our all-time favorite Jennifer Lawrence hair looks. Here, our official ranking of the best Jennifer Lawrence hairstyles ever. We dare you to get through this list without calling your stylist.

This pin-straight style is channeling major '90s vibes, no? An oft forgotten look of JLaw's, this one came on the heels of her dark locks from "Silver Lining's Playbook." The one-dimensional color is a drastic difference from the highlights we've seen on her in recent years, but the sleek style and shiny finish make it work.

To recreate, apply a straightening shine serum to damp hair, such as Aveda Smooth Infusion Glossing Straightener, $24. Blow-dry with a round brush, then straighten from root to tip with a flat iron and expect to be repeatedly asked for your autograph.

Two years before Lawrence shook the beautysphere with her killer 2015 lob, she flaunted this becoming version. Her hand-painted bronde highlights and piecey bangs created the illusion of volume, especially when styled with loose, tousled waves.

DIY the look on collarbone-length hair by creating a slight side part and curling hair away from the face, using a 1-1/2 inch curling iron. If you have bangs, brush them slightly to the side and set the entire look with a medium-hold hairspray.

Who could forget Lawrence's smokin' hot hair from the 2011 Academy Awards? Lawrence was all Hollywood glamour in this va-va-volumized layered blowout and golden blonde color. This was basically the moment when our voracious JLaw girl crush began.

This is not your typical weekday blowout. To recreate the look, apply a volumizing cream to damp hair, such as Oribe Imperial Blowout Transformative Styling Créme, $68. Use a small round brush to blow-dry hair, leaving two-inch sections of hair wrapped around the brush for up to thirty seconds, then setting with a cool shot. Create the look on layered hair, and watch the fan mail roll in.

Lawrence's pixie was one of her more controversial cuts. But styled with this messy, side-swept texture, we're fully onboard.

If you're rocking a crop à la JLaw 2014, use a dollop of pomade (try Moroccanoil Texture Clay, $26) to rough up the strands, creating that piecey, playful finish.
