History Main / HairstyleInertia

* In ''Manga/MagiLabyrinthOfMagic'', the BigGood Sinbad has been shown to have the same, choppy, side-swept bangs and [[RapunzelHair knee-length ponytail]] with an IdiotHair since he was fourteen, fifteen years ago. Yunan and Scheherazade have also had the same hairstyles they have now.

** Piper notably rarely changes her hair as the series goes on. By Season 3 it grows to waist length and stays that way. Even in a TimeSkip that shows her as an old woman, it's still that length. The actress who plays elderly!Piper was even cast because of her RapunzelHair.

* ''VideoGame/PokemonBlackAndWhite'': As shown in the opening cinematic, the 20-year old [[AntiVillain N Harmonia]] has the same RapunzelHair tied into a ponytail that he had as an orphaned child.

* Creator/HollyMarieCombs is known for having the same dark RapunzelHair since ''Charmed'''s third season, mentioned above.

* Creator/OliviaHussey has always been known for having her black RapunzelHair as in ''Film/RomeoAndJuliet''. The exceptions are a TwentiesBobHaircut in ''Literature/DeathOnTheNile'', fitting the film's 1930s setting and a shoulder-length cut in ''The Pirate''. She wears it a little shorter these days but still quite long.

* Suzaku, Nunnally, Kallen, Euphemia, etc. in ''Anime/CodeGeass''.

* Miko from ''Manga/KaguyaSamaLoveIsWar'' is shown to have the exact same GirlishPigtails in flashbacks that she does in the present, which help to reflect her childish naivete. An ImagineSpot that she has in the Doujin spin-off also depicts her with this hairstyle as an adult.

** If photographs seen in ''Dual Destinies'' and ''[[VisualNovel/PhoenixWrightAceAttorneySpiritOfJustice Spirit of Justice]]'' are any indication, Apollo's had his dual-antenna hairstyle since he was a very young boy. And according to [[spoiler:his father's Divination Seance, those antennae have been there ''since he was a baby'', when he was otherwise completely bald]]. Likewise, Trucy's hairstyle has been the same since at least she was 8, [[spoiler:sporting similar "antennae" in her own hair, which connects her to Apollo as half-siblings]].

* In ''Series/MammaMiaHereWeGoAgain'', Donna, Tanya and Julie all had the same haircuts in their early twenties as they did twenty years later.

It is not an ImportantHaircut -- those happen in series and are, as the title says, important to the plot. It is also not an ExpositoryHairstyleChange, which usually does not flashback to a character's childhood. This trope deals only with characters keeping the same hairstyle from childhood until the present time. The opposite of this trope is HairTodayGoneTomorrow. This trope can be the opposite or an example of the FunnyFlashbackHaircut if the unchanging hairstyle is used as a joke.

* ZigZagged in ''Manga/{{Trigun}}'', while Vash [[spoiler: changes his hair color becomes darker every time he uses his powers]], in the anime he and Knives had long hair when they were kids. But in both the manga and anime, Vash grows his hair after certain incident and adopts a different identity. The same goes to [[TheSixthRanger Livio]]

* ''Manga/{{Naruto}}'':
** Averted and played straight in ''Manga/{{Naruto}}''. Practically every major character besides Chouji, Lee, Tsunade, Sakura, Ino, Nagato, Kushina, Hinata, and Hanabi. The DistantFinale also has most of the characters having new hairstyles.

Hairstyle Inertia is the phenomenon where adult or teenage characters who {{Flashback}} to a time in their childhood are frequently shown to have the exact same hairstyle, though those with long hair usually have shorter-- but not short-- hair. Pigtails, ponytails, braids, or other hairstyles that require long hair are also shown to be stubbier and shorter; is often used for SpinoffBabies.

[[folder:Anime and Manga]]

* Urashima and Otsuu from ''LightNovel/OokamiSan''.

* Young Clark Kent/Superboy, in continuities where he exists, has the same hairstyle(s) as Adult Clark/ {{Superman}} (short, slicked back as Clark, spit-curl as hero). In continuities where Clark ''wasn't'' Superboy, Young Clark usually has the spit curl.

[[folder:Films -- Animated]]

* Plot point in ''{{WesternAnimation/Tangled}}'', Rapunzel has to keep her hair long because it loses its magic when it's cut. [[spoiler: It's all cut short at the end]].

** Hermione however is always described as having the same bushy hairstyle across all seven books - save for straightening it once at the Yule Ball. Again averted in the films, as her hair is blonde in fifth year[[note]]Emma Watson had been required to dye it blonde for ''Literature/BalletShoes''[[/note]].

* ''{{Series/Charmed|1998}}'':

** Averted as a RunningGag with Dr Hibbert - every time he's appeared in a flashback, he's had a different haircut, usually one that's associated with the time period in question.

* In ''WesternAnimation/TheLegendOfKorra'', Katara's hairstyle remains nearly the same 70 years later when she's Avatar Korra's Waterbending master, complete with hair-loopies.

** {{Justified}} in ''Series/ResshaSentaiToQger'' due to [[spoiler:the rangers being literal children in adult bodies. In the movie, which takes place ten years after, the girls have changed their hairstyles; the boys not as much, though their child actors are marked more by their outfits than by their hairstyles.]]

** {{Justified}} in ''Series/ResshaSentaiToQger'' due to [[spoiler:the rangers being literal children in adult bodies. In the movie, which takes place ten years after, the girls have changed their hairstyles; the boys not so much.]]

* Happens often in ''Series/SuperSentai'', when the child actors playing the child versions of the rangers in flashbacks have their hair styled in the same way as their adult counterparts. Not quite so egregious since Japanese hairstyles tend to look pretty similar, so having the child have the same hairstyle as the adult is a way to mark who is who, especially if the adult has reddish brown hair.

* Music/BrianMay of Music/{{Queen}} has kept the same haircut (huge, dark, and curly) for the past 40 years, but eventually let it go gray in the mid-2010s.

-->-- ''Anime/DragonBallKai''

* Played straight in ''Manga/KimiToBoku'' for every boy except Chizuru and Shun. Even with Shun, he starts out as a LongHairedPrettyBoy but cuts his hair early on to look like his preschool haircut.

* Everyone from ''Webcomic/AxisPowersHetalia'', except for the DoubleSubversion in the strip where England in the Middle Ages sees France's fashionably long hair and grows his out, only to have the style become unpopular. He plans on keeping it but lets France adjust it a bit. Instead France cuts it back to what it originally was, to England's chagrin.
* ''Manga/DragonBall''

* ZigZagged in Trigun, while Vash [[spoiler: changes his hair color becomes darker every time he uses his powers]], in the anime he and Knives had long hair when they were kids. But in both the manga and anime, Vash grows his hair after certain incident and adopts a different identity. The same goes to [[TheSixthRanger Livio]]

* West of the ''Franchise/KingdomHearts'' fic ''FanFic/{{Reconnected}}'' has worn her hair in twin pigtails since she was six years old.
