This happens all the time. In the recent Netflix show 13 Reasons Why, the main character starts with long hair. Later she cuts it, then kills herself. We would have included a spoiler alert, but she's a girl in an article about girls in TV shows getting haircuts, so you already knew what would happen.

Netflix How did her parents miss all the signs? That hair is far shorter than before!

Sometimes the resetting-your-life-with-a-haircut trope is played for laughs. In Mean Girls, we learn that after Regina George made fun of Janis for being a lesbian, Janis dropped out and "all her hair was cut off, and she was totally weird." But most times, these haircuts are very, very serious. In the movie Joy, Jennifer Lawrence gets swindled out of all her money. Explaining how that affected her character could be done with a scene of her at her bank, followed by a montage of her scowling over bills and repo men. Or you can do what they did:

20th Century Fox A fucking no-more-of-this-bullshit HAIRCUT.

It's not impossible for a real human person to deal with adversity by running to a mirror and hacking off their own hair. Do whatever makes you feel better. But it is truly strange how every single fictional girl does this. Hannah Horvath from Girls goes full haircut after a mental breakdown, and you know she's serious because she uses dull-ass utility scissors. Her life is so out of control that she has to chomp and chew her hair off.

HBO "I guess I just feel like my cliche mental breakdown haircut should have its own unique voice, y'know?"

You might remember this from another HBO show, The Newsroom, in which Maggie dealt with trauma in Uganda. The show kept the details a secret from the viewers for a while, but it was obvious they were bad, because she took a pair of scissors to her head and her hair went from "long and blonde" to "wad of cranky orange shapes." In real life, you would call it a silly and terrible decision. On TV, you call it a terribly serious and gritty reboot of her character.

HBO "Can you make the character look as if she is no longer capable of joy? Like darkness is all she knows. A Ronald McDonald wig? Perfect!"

Cinderella was a weak-willed scullion maid getting bullied so badly that she had to talk to mice. But you give her a sparkly blue dress, and suddenly she has the confidence to land the most eligible bachelor in the land.

Walt Disney Pictures "A man wants to sleep with me! I win! Thanks, blue dress!!!"

Once you start to look for it, you'll see it everywhere. In BioShock Infinite the female lead wears a blue dress. And it's not only cartoon ladies dealing with magical circumstances who wear them. In Devil In A Blue Dress, the costume designer never considered saying, "Making this lady look like trouble would be way easier if you guys called this movie Devil In A Pink Romper." In Sin City: A Dame To Kill For, they had to make Eva Green look like an unstoppable force of sexual domination. To show these traits, they put her in two different outfits: fully nude and, you guessed it, a blue dress.

The Weinstein Company Here's the blue dress one!

On the only other show about white professionals who hang out in New York, How I Met Your Mother, Lily also deals with her feelings by shoveling ice cream into her face. She makes the trope her own by using a wooden spoon.

20th Television "Ha ha, like the kind you'd use for cooking! That's not an ice cream spoon, you goddamn idiot! Ha ha! Ha ... ha. S-sorry, Lily."

It shows up in Hitch, Legally Blonde, Thor: The Dark World, the Bewitched remake, and countless other places. It's such a tired device that even the filmmakers using it know it's tired. This means they have to start adding a hook to it, like when Amy Schumer drowns her sorrows in ice cream in Trainwreck, but does so with a martini in a proper martini glass. The thing's even got a spear of green olives. It's a traditional classy cocktail that requires a person to own specialized equipment and ingredients, then go through a prohibitive series of steps to prepare it, and when you stick it next to a tub of ice cream, they still look like a lazy slob. That's how sad ice cream seems in movies.

Universal Pictures "Boom. Time to kill myself!"

Paramount Pictures EVIL!!!

Cool Hand Luke also employed this method to demonstrate which bad guy is the no-shit-fuck-your-life-up bad guy. The character in question is a prison guard in a movie in which the hero is a prisoner, so we weren't expecting him to be the comic relief, but when you see him scowl from behind glinting sunglasses, you instantly know he's pure sociopath.

Warner Bros. Behind those sunglasses are nothing but two holes filled with spiders.

You can almost tell the degree of humanity a character has by how much of their eyes show through their glasses. If they're a complicated villain driven by broken idealism, you might see some of their eyes. If those eyes are completely hidden behind sheets of white reflection, watch out, because they are the completely soulless kind of evil.

Lucasfilm Nazi uniforms are also good for identifying the really bad guys.

In Who Framed Roger Rabbit, the main antagonist wants to get rid of all the fun cartoon characters so badly that he creates a special acid capable of killing them. You might think "Who would want to do that?" until you see Judge Doom and his fully shiny glasses.

Walt Disney Pictures Oh, it's because he's PURE EVIL. That makes sense.

In Sin City, there's a character who speaks only in fingernail karate. How do you make someone like that anything other than rad? Well, they cast Elijah Wood, gave him a Bible and a Charlie Brown sweater, and most importantly, put him in fully shiny glasses.

Miramax That's how evil shiny glasses are: They make Frodo holding a Bible in a rocking chair the most obviously evil thing you've ever seen.

In My Cousin Vinny, Joe Pesci walks into a country bar and beats one of the men there at pool. In our world, this kind of thing happens all the time, and we would never expect the loser to immediately attempt murder. And yet when exactly that happens in the movie, no one is surprised. Not even Vinny. Of course the man tried to kill him -- he's a billiards player! In a movie! It's weird, right? It's a universe in which everyone who plays pool is a murderer and the game itself makes them want to murder, but bar owners are still putting them in their bars?

20th Century Fox Pool table control is for whiny liberals. The only thing that can stop a bad guy with a pool table is a good guy with a pool table.

In Terminator 2, Arnold Schwarzenegger walks into a bar fully nude and jacked beyond reason. And if he walked into a bar with only a dartboard, things would have been fine. But he walked into a bar with a pool table. They took one look at this terrifyingly powerful lunatic and instantly decided to kick his ass. As usual, it didn't go well, but the story always starts the same: criminal assault by pool player.

TriStar Pictures Terminator 6 reveals that the war began when a human hit a jukebox with pool cue.

If you told Steven Seagal you can use a pool table to play a game, he would have no idea what you're talking about, because every time he's ever been near one, someone has tried to break a pool cue over his head. Nothing says "a fight is about to start" in a movie more than a pool table, and as moviegoers, we're somehow okay with it, despite many of us only getting into life-and-death battles once every five or six games.

Even non-terrible films like Pan's Labyrinth might use a nosebleed to tell us how dead people are. The movie is a tornado of eyeballs and goo, and it's not clear what the rules are or what happens at the end. Until you see Ophelia's nose bleed. Then you know, without question, that girl's dead.

Warner Bros. No medicine on Earth can bring back a movie character from a nosebleed.

When Naomi Watts watches the cursed video in The Ring and she's doomed to die in a week, the movie lets us know this isn't some hoax or prank or hallucination. They give her a nosebleed to make it clear that YES, she's about to die from the curse of a very real ghost girl murderer. And when she manages to escape the curse, the movie can reassure us it worked by having her nose stop bleeding.

DreamWorks Pictures You see how handy it is?

If you don't have the budget for all that nose blood, you can also mark your characters for death with a cough. Coughing, as you may know, is quite ordinary in real life. In fact, it's so ordinary that we literally treat it with candy. But in a film, a cough is certain doom. If you see a character coughing for any reason other than being bad at weed, the editor might as well skip right to their funeral scene. As soon as a cough left Nicole Kidman's lips in Moulin Rouge, you knew she was dead. And you were confident Doc Holliday was going to win every gunfight in Tombstone because once he coughed, you knew that was going to be his cause of death.
