"Do not then winde up that lightOften, when a female character is particularly serious or uptight, her hair will be serious and uptight too — pulled back in a tight bun, or something of that sort. When said woman gets a love interest and starts to loosen up a little (as such characters almost inevitably do), she will start wearing her hair down, or at least in a looser style. Unlike the hair-letting-down that is part of Beautiful All Along, this is never part of a makeover and is not necessarily commented upon by the other characters. The hairstyle in this case is more of a quick visual indicator of the character's relaxation. If the new style is noticed, there will be comments along the lines of "you should wear your hair like that more often." This is a subconscious appreciation of the heroine's new state of relaxation. A variation of this can be seen in shows for younger girls. If the girl has low self esteem, she will wear her hair down and over her face. At the end of the show, when she has gained some confidence, she will pull her hair back to signify the change, opening her face and no longer hiding. Sometimes the letting down is actually done expressly to make the character look more attractive, with existing admirers having their desires heightened while those who hadn't noticed them before suddenly find them to have been Beautiful All Along. This is likely related to the medieval notion that long hair was an indication of the owner's sexual prowess and concupiscence, and in fact incited others to arousal if it were not hidden, concealed, or worn up in some fashion. See also Important Haircut. Compare Slipknot Ponytail, where one's hair goes au naturale because they are being badass, and Wild Hair, where it is normally worn loose. Also compare Shaking Her Hair Loose when the hair is dramatically undone on camera.

Anime & Manga
- Variation after the events of Magical Girl Lyrical Nanoha StrikerS, which has Teana losing her Tsundere twin-tails after she had matured into a highly competent and reliable leader.
- Inverted with Nanoha. She loses her tight little pigtails as she grows up, and is shown wearing her hair out, but her personality doesn't change at all, since she was already very mature. She's back to wearing it tied up in the third season, albit looser and in a single ponytail.
- Setsuna of Mahou Sensei Negima! not wearing her hair in a Samurai style side-ponytail in the later chapters once she starts growing out of her intensely serious, near-deadpan demeanor.
- Fullmetal Alchemist has First Lieutenant Riza Hawkeye, who is normally seen with an efficient, no-nonsense bun, but generally lets her hair down when she's seen off-duty. In the 2003 anime, Hawkeye doesn't take her hair down until the very last episode, when she visits wounded comrade Roy Mustang.
- Mobile Suit Gundam Wing's Lady Une normally keeps her hair up in a tight bun◊, but lets it down◊ for her less uptight alter-ego "Saint Une". When both personalities merge back into the real Une, she decides to keep her hair down from then on.
- In The World God Only Knows, when Mari Katsuragi lets her hair down, someone will get hurt very badly (and she'll look good at it). Elsie on the other hand just gets prettier.
- No-nonsense Dr. Chiba in Paprika wears her hair in a neat bun; we only see it down when she's asleep or in the process of transforming into her free-spirited dream avatar Paprika.
- In Yu-Gi-Oh! 5D's, Aki reverses this: when she lets her hair down, it's a bad sign. The band holding her hair up is designed to hold her psychic powers in check. When it comes off and her hair is let down, run.
- Gundam X's Tiffa Addil has a ponytail but when Barrier Maiden Lucille Lilliant "borrows" her body to ask for help from Jamil, Tiffa's adoptive father as well as her former pupil, she lets it loose.

- In Pokémon Special, following the rather traumatic incident with N at the Nimbasa Ferris Wheel, White keeps her hair out of its usual ponytail, signifying her depression. She ties it back up when she somewhat comes in terms with herself. Incidentally, fans agree she looks much prettier with her hair down.
- Played very unusually in Puella Magi Madoka Magica. Originally, Homura has her hair done up in twin braids, but eventually lets it down. This doesn't signify her becoming more relaxed in the slightest, though; in fact, it marks her transition into being serious. So you could say it's inverted, only it's also played straight, because the character was previously shy, so it signals a growth in confidence. On the other hand, it also seems to represent the loss of her innocence. So it's hard to classify where this one lands.
- Kyoko also later does this in the fight with Oktavia von Seckendorff to show that she finally became a better person.
- Ringo Noyamano from Air Gear lets her long hair loose when she becomes Ikki's link tuner.
- Mobile Suit Gundam Seed Destiny has Meyrin Hawke, who keeps her hair in Girlish Pigtails.

At the very end of the series she puts it back up again, to the disappointment of some fans who thought she looked a lot more mature with it down.
- Retsu Unohana of Bleach is an inversion. She's gentle and motherly with her braid, but when her hair is let down...
- Young and overworked Ritsuko from The iDOLM@STER 2: The World Is All One!! lets her hair down and ditches her office attire after some cutting words from Iori rattle her confidence. This shedding her of her profession appearance reemphasizes Ritsuko's age, which was also something that was bothering her.
- Space Dandy:
- A particularly badass example is seen in the second episode. Scarlet, almost always seen with an uptight bun, lets her hair down before demolishing a team of elite super-mafia aliens.
- Later in the series, when she has Dandy be her pretend date to make her old stalker boyfriend jealous, Dandy is impressed with how good she looks with her hair down.
- Phyllis Jaraba in Super Robot Wars Original Generation Coffin of the End normally has her hair braided up and also wears glasses. She takes off her glasses and lets her hair down after she's Brainwashed and Crazy by the giants of La Gias.

- Nightfall from ElfQuest can't be described as uptight by any stretch, but she does keep her long brown hair under a headscarf except in her most intimate moments.
- Rapunzel has the titular character's evil stepmother Gothel and the prince repeatedly asking her to do this so they can climb up to her tower. As Freud would point out, this releasing of her hair was not just for utilitarian purposes, considering that Rapunzel eventually gets pregnant from all this, um, "relaxation" with her prince.
Films — Animation

As she enters a, well, unconventional romance with her boss, she starts to wear it down, especially at moments when she clearly feels most confident.

- Played in reverse in Pleasantville: Jennifer starts out with her hair down, but becomes more serious as the movie goes on, and pulls her hair back at about the same time as she discovers literature.

- Angela Drake in Brewster's Millions. When the movie begins, she's purely professional with her hair up, but near the end she sports a lady 'fro.
- Saavik, in Star Trek II: The Wrath of Khan, once in an elevator, and once at a more emotional moment. In Star Trek III: The Search for Spock, she is seen with her hair down most of the time, and has certainly loosened up some.
- Our Man Flint. After she's lured Flint to her apartment, Gila does this to signal to him that she's in the mood for love.

Nowadays as a cold and detached Proper Lady she only wears it up. She does let it down for a moment after an argument with Edmund, but actually doesn't do this in the film. Her hair remains up after her Character Development.
- Mitsuyo in Villain is a rather dark example; she starts the movie with her hair in a tight ponytail and lets it down when she decides to go on the run with her murderer boyfriend instead of turning him in to the police. After he's arrested she puts it up again.
- In Something New, this is used as a juxtaposition between the characters of Brian (who wants Kenya to have her natural, kinky hair) and Mark (who wants her to keep artificially straight and buttoned-down). The metaphor is obvious.
- In Cursed we are introduced to Ellie with her hair tied up in a bun. After being bitten by the werewolf and thus gaining a natural sexual aura she is always shown with her hair down with the men gawking appropriately. One of her co-workers mentions how much nicer she looks with her hair down.

- The Hunger Games: Katniss is only shown with her hair down when she is at her most vulnerable. There's some justification to this, since her iconic braid is just how she wears it when she's hunting or in the games.
- Similarly used in Divergent with Tris's hair. While going through the Dauntless Training from Hell, it's usually tied back in a ponytail. During intimate moments with Four, her hair is usually down. When she confesses that she's a Divergent her hair is down.
- Done the other way around in American Hustle with Rosalyn. She and Irving are in the middle of a rocky marriage for the bulk of the film, and she wears her hair up. In their wedding photo - and it's implied they were happier when they got married - her hair is down.
- Sunshine Cleaning:
- Norah only has her hair down when she's around Lynn, which is when she also starts opening up and connecting with another human being.
- Rose also only wears her hair down while meeting Mac in the motel for their rendezvous. She also wears it down for the baby shower - which is when she realises that she is finally happy with her life.

- The Legend of Billie Jean shows Putter with her hair down after she gets her first period. It's been tied up in Girlish Pigtails for the majority of the film.
- In A Brother's Price, Jerin usually keeps his hair in a practical braid.

There's also the incident when Princess Lylia talks him into kissing her. She undoes his braid, a physical symbol of the unchaste act she got him to commit. Princess Ren re-braids it later, after scolding Lylia.
- Hester Prynne lets her hair down during her secret forest rendezvous with Rev. Dimmesdale in The Scarlet Letter.
- Played for laughs in Harry Potter and the Goblet of Fire, where Professor McGonagall makes a remark about letting our hair down (in reference to the Yule Ball). Lavender and Parvati start giggling, and Harry's narration notes that it doesn't look like she's ever let her hair down in any sense.
- In A Tree Grows in Brooklyn, Francie's mother won't let her get a fashionable bob because a woman should have long hair as her "secret" beauty that only her lover/husband (well, presumably Katie means husband) gets to see when she unpins it at the end of the day.
- In the Spaceforce series, the culture of the Taysan Empire considers unbound hair to be indecent. When Jay pulls Ashlenn's hair bindings out and forces it to fall loose when he persuades her to elope with him, he might as well be stripping her.

- Captain Janeway wore the Bun of Steel the first few seasons of Star Trek: Voyager. It disappeared when the writers decided to drop her "This is a Starfleet vessel" persona and let the poor girl loosen up a bit (or when they started stuffing up her character). Likewise Kes ditched her bobbed wig for long flowing locks, but that was because Jennifer Lien was getting a reaction to the adhesive used to stick her pointy ears on.
- Seven of Nine also wore her hair down in later episodes when she was doing social experiments in the holodeck. She'd immediately pin it back up when reporting for duty.
- Star Trek: Enterprise. Science officer T'Pol has the standard Vulcan Sci-Fi Bob Haircut, but in "In A Mirror, Darkly" she's got long flowing hair down past her shoulders, in accordance with the Evil Is Sexy look of the Mirror Universe.

- Parodied in an episode of That '70s Show. At the start of an episode, Kelso gets a ticket from a beautiful female cop who wore her hair down. Later that same episode, he meets the same female cop, this time with her hair in a tight bun, and does not recognize her at all. (Averted somewhat however, as he attributes her previous sexiness to the uniform instead of her hair).
- Det. Dani Reese from Life wore her hair pulled back in Season 1. In Season 2, she wears it down, reflecting her new, considerably more relaxed, attitude towards Crews.
- Invoked in an episode of Better Off Ted. When Veronica is told that she is too intimidating, she starts wearing her hair down as part of an attempt to be more approachable, and hates it.

As she becomes more comfortable with people, and stops being the Alpha Bitch, she slowly moves to less uptight hairstyles. Season 9 she wears a series of cute functional hairbands, finally in Season 10 she moved to her hair being unadorned unless for practical reasons for whatever activity is going on. Other characters have done the switch to hair down for Beautiful All Along reasons.
- Ami's mother in Pretty Guardian Sailor Moon is a doctor and the first time we see her is at the hospital with her hair in a bun.

- In Glee, head cheerleader and the Alpha Bitch Quinn wears her hair in a tight ponytail for most of season 1, until her teen pregnancy is revealed and she is forced to quit the cheerleading team. She starts wearing her hair loose and becomes a more compassionate person. At the start of season 2, having given up her baby for adoption, she goes back to her original tight ponytail hairstyle. (Her more relaxed personality is also reflected in a change in wardrobe— from the sharp cheerleader uniform to more casual clothes.)
- When Elvira, Mistress of the Dark lets her Beehive Hairdo down, she really lets it down! You wouldn't expect such a small beehive to have so much hair in it.
- Annie in Community episode Debate 109. Notable for not only starting one of the most enduring and influential ships in the series but also turning her into a Breakout Character and one of the main members of the cast due to the overwhelming fan reaction.
- Inverted on NCIS. When we meet Ziva, she's a wild, seductive, crazy, Israeli, ninja assassin. Her hair is also absolutely wild. As she becomes more friendly, open, and relaxed, her hair is also tamed somewhat. She's no less badass with her hair in a ponytail, but a little less...crazy.

- Played with a man, and in a completely different meaning, in Les Misérables the musical. Javert does this in almost every performance during his BSOD song. It symbolizes his strict personality being splintered, but when it comes to Philip Quast, it's clearly Fan Service.
- Magda in Tanz Der Vampire. Human!Magda has a skinny red braid. Vampire!Magda has voluminous, cascading red tresses.

- At the end of Metroid: Other M, Samus is seen out of her Power Suit and Zero Suit, and into what looks to be a uniform, hair let down and rather Rapunzel-ish. Though she ties it back into a ponytail after a while, the dialogue and her expression easily convey her feeling of peace and coming to terms with Adam's death and the resolution of the Bottle Ship incident.
- Chris Lightfellow from Suikoden III dons a casual outfit for her 3rd chapter. Her character portrait for that segment of the game even looks a good deal more relaxed than the scowl she usually settles with.

- Whateley Universe: Discussed in The Big Idea with Delta Spike:
Harlan had a brief flash of déjà vu, looking at Delta Spike. Then he realized that she was the picture of a Hollywood ‘Girl Scientist’, the one who’s supposed to be a drab little geek, but you know that the second that she takes off her glasses and lets her hair down, she’s absolutely gorgeous. Delta Spike had long glossy black hair that was tied up in a style that really didn’t suit her. She wore a pair of thick clunky-looking black frame glasses that couldn’t have done a better job of disguising her classic features if she’d designed them for just that task. Still, she smiled prettily enough.
- At the beginning of The Powerpuff Girls episode "The Main Event", as the girls wake up from their sleep, we get to see Blossom with her hair down.
- A variant in The Simpsons episode "Homer Alone." Marge treats herself to a spa visit but is too worried about her family to relax.

She does put it back up into a bun after the song, though she does wear a blue dress from that song on instead of the black one she wore before.
- Avatar: The Last Airbender: For the first two Books in the series, Katara was known for her "hair loopies", though they often came undone during fight scenes. Come "Book 3: Fire", she finally decided to simply wear her hair long as part of her disguise, while they were in Fire Nation territory.
- Interestingly enough, this was a conscious decision on the part of the writers, who, during commentary for "The Waterbending Master" episode, admitted they preferred Katara's look with her hair down. Which they cited as the reason for usually having her hair unravel during her fight scenes.
- The Avengers: Earth's Mightiest Heroes! has Major Carol Danvers undo her bun once she starts fighting crime as Ms. Marvel, using the superpowers she developed after exposure to Kree energy. She also proceeds to wear her hair like this in her civilian identity. Though it's possible she always let her hair hang loose when she wasn't at work, so tying it back in a bun or a ponytail was just for the pragmatic purposes of her military job.
- Adventure Time:
- One of the Rule 63 episodes features Fionna removing her hat and revealing her very long hair while singing with "bad little boy" Marshall Lee.

- My Little Pony: Friendship Is Magic:
- A brief variation of this shows up in the episode "Sisterhooves Social". Rarity normally has her mane curled, but near the end of the episode, she goes out in the rain to play with her sister, and her mane gets straightened by the water. While it's unintentional on her part, it still fits, as it's an indicator that she's willing to relax her desire to keep up appearances in favor of spending time with her sister. Rarity's mane gets straightened by the rain again in "Magical Mystery Cure" and "Rarity Takes Manehattan".
- Pinkie Pie's mane goes flat whenever she's in manic-depressive ("Pinkamena") mode.
- Kimiko Tohomiko undoes her bun by removing the Tangle Web Comb in order to use it as a weapon during a showdown with Jack Spicer in Xiaolin Showdown episode "Tangled Web!".
- Some girls and women who ordinarily wear their hair up will incite the kind of reactions shown in media if, for some reason or other, they have their hair down and they're out in public to get these reactions in the first place.
- Women and girls with Rapunzel Hair will sometimes wear it up everyday for practical reasons (to protect the ends from damage, keep it from getting tangled, etc.) and only let it down for special occasions.
- In medieval times, doing this was seen as a sign of virility and desirability for men (hence the Long-Haired Pretty Boy being popular), but as an indication of vain, sinful lust in women. Viewing hair was considered scandalous outside of the bedchamber, and letting it down was thought to be both uncouth and a form of teasing arousal, resulting in most women wearing theirs up and/or under veils, scarves, hats, and headdresses. Women who became nuns and thus vowed themselves to a life of celibacy and purity were especially prone to averting this trope, if they didn't have an Important Haircut to remove it altogether.
