HairColors are an easy way to distinguish one person from another at a glance. At times, it might drive a person to dye or even bleach their own hair to change its color (blonde is a common goal, due to the {{stereotype}}s of it being [[EveryoneLovesBlondes more glamorous]]). But some people aren't satisified with just one hair color. Oh no. Their hair has to keep changing color frequently. The new shade can be common, [[ImplausibleHairColor implausible]], or even [[YouGottaHaveBlueHair outright impossible]]. The changes must happen a number of times, and they may be justified by use of hair dye, or any sort of AppliedPhlebotinum -- up to and including actual {{magic}} (though it's not ''necessarily'' a case of MagicHair). It doesn't even have to happen to real hair, so characters who constantly swap wig colors come under this trope.

The color changes may pass without comment from others in the work, or drive someone up a wall trying to figure things out. Sometimes, even the subject of the changes might not appear to notice or care; in other cases, they might be pleased. The changes can be accompanied by a [[TheMakeover makeover]], but this is less likely if they take place regularly or are a result of [[MoodSwinger mood swings]]. [[HilarityEnsues Hilarity can ensue]] if the character hates what happens to their hair while being powerless to stop it.

This trope can occur in any medium, but some are more common than others (e.g. [[VideoGameTropes video game]] examples are near non-existant). Naturally, this includes RealLife, though due to the effects of repeated dyeing[[note]]that is, hair becoming rough, bleached, falling out, losing oils, breaking, and generally becoming a pain to care for and style,[[/note]] [[SimpleMindedWisdom most people don’t do it]]. Due to happening many times on a single person, it isn’t a type of ExpositoryHairstyleChange. Usually.

Compare KaleidoscopeEyes for the same thing in a different place, and MulticoloredHair, which is strictly about hair that is ''simultaneously'' of multiple colors/shades. Of course, the two tropes may overlap sometimes. Compare and contrast ExpressiveHair, when the hair changes style. Supertrope to PowerDyesYourHair, where the color change only occurs due to a transformative power-up.

One of the CommonMarySueTraits, along with being a way to give someone a [[DistinctiveAppearances Distinctive Appearance]]. See also LockedIntoStrangeness, for permanent hair colour changes. May be a result of someone [[IJustWantToBeSpecial just wanting to be special]] or AnimeHair (where it can overlap with YouGottaHaveBlueHair). [[VoluntaryShapeshifting Voluntary Shapeshifters]] often have this, as can [[EmoTeen some]] [[PerkyGoth depictions]] [[{{Hipster}} of]] [[DelinquentHair teenagers]].
! Examples:


[[folder:Anime and Manga]]
* Motoko in ''Manga/{{Change 123}}'' has three SplitPersonalities. When she switches between them, many of her physical features change, including hair color.
* When Light and L confront each other in ''Manga/DeathNote'', or meet each other on the street, Light shines a deep, blood-like red, and L an almost naval blue. Sometimes this appears as a tiny aura around their bodies, other times their hair and eyes glow that color. Their hair color can also indicate mood.
* Fujiko Mine of ''Characters/LupinIII'', during four TV series, five feature films, and dozens of {{Made For TV Movie}}s, has gone through various shades of blonde, brunette, and red. Sometimes it's as part of her role as a MasterOfDisguise, but it usually comes with no explanation other than DependingOnTheArtist.
* Seika Higashiyama in the ''Anime/SuitePrettyCure'' series has hair which is a different color in all of her appearances (sometimes it's even [[MulticoloredHair more than one color at once]]).
* ''Anime/UruseiYatsura'': In the manga, Lum had full-blown rainbow-colored hair that shifted colors. As the manga progressed, Creator/RumikoTakahashi changed Lum's hair color to green to match the anime, since it was changed there for ease of drawing.
* This happens for no fathomable reason in ''VisualNovel/QuestTwilightPrinceProphecyChronicals''. Donna's hair keeps changing from a grayish brown to full-blown pink, while Ebert's can be green or brown.
* In color chapters of the ''Manga/DragonBall'' manga, Karin's fur is never the same color twice. This is never commented upon. (For what it's worth, he was based on a ''black'' cat...)
** Bulma's hair also repeatedly changed color. The first few color chapters have her with purple hair, while later ones go back to the turquoise color that the anime used mostly.
* In ''Manga/SaintSeiya'' and its various spinoffs, Gemini Saints subject to dual personality issues, such as Saga or Paradox, have this happen whenever the personality in charge changes. It also happens to [[spoiler: Shun]] during the Hades Saga when [[spoiler: Hades]] takes over his body.

[[folder:Comic Books]]
* Delirium from ''ComicBook/TheSandman''; her hair color changes depending on her mood. It's also multicolored at any given time.
* Ramona Flowers dyes her hair every two weeks, which Comicbook/ScottPilgrim freaks out over. In ''Film/ScottPilgrimVsTheWorld'', Knives tries to dye her hair blue in order to compete with currently-blue-haired Ramona.
* Rick Hunter of ''ComicBook/BoosterGold'' has this and KaleidoscopeEyes.
* ComicBook/TankGirl's hair colour changes frequently, while rarely being anything that would naturally exist.
* Midnighter of ''ComicBook/TheAuthority'' supposedly constantly changes his hair colour. This is a mixture of AscendedFanon and AscendedGlitch: because he was so rarely seen without his cowl, different colourists kept colouring his hair random colours in the very few panels where it was visible, and fans came up with the idea that he keeps redying it.

* The ParodySue of ''Fanfic/NineMenAndALittleLady'' has changing hair colour; it starts as flame-red but both Sam and Boromir comment on how it changes, Sam even using the [[PurpleProse excessive adjectives common to Sue descriptions]].
-->''Myrishna (or was it Aelithea?) had eyes like stars,\\
[[KaleidoscopeEyes Or maybe emeralds... or were they pale?]]\\
But her hair was like mithril!\\
Or night... or sunshine... or maybe ale.''
* From Fanfic/KillLaKillAU, we have this with Ragyo who, true to canon, has MulticoloredHair, and it apparently reacts to her mood, as was shown in a few comics

* In ''Film/EternalSunshineOfTheSpotlessMind'', Clementine frequently re-dyes her hair.
* Violet from ''Film/UltraViolet'', partially because of how the film is designed to resemble a comic book.
* ''Film/DiamondsAreForever'' - when Bond first meets Tiffany at her apartment, he's perplexed to see her change from a blonde to a brunette to a redhead in quick order.
* Talia of ''Film/The6thDay'' has a different hair color (usually [[YouGottaHaveBlueHair something bright]]) each time she comes back in a new body. She even gripes about having to constantly redye it.
* Natalia Tena's portrayal of Tonks (see below) doesn't change her hair quite as much as her book counterpart but is still shown with purple, red, white, brown and blonde hair across four ''Film/HarryPotter'' films.
* ''Film/TenInchHero'' has Priestly, whose mohawk changes color changes in every scene. At one point, it's even two different colors.
* In ''{{Film/Werewolf}}'', Yuri's hair seems to change color and style in practically every scene due to poor continuity editing. The movie was cobbled together from shoots that happened months apart. And even when his hair ''is'' the same, inconsistent lighting makes it look different.

* ''Literature/HarryPotter'':
** Tonks often changes her hair color; it is usually a shade of bubblegum, but can turn [[FieryRedhead ginger]] when she’s angry, gray for a disguise, or any number of other colors at her every whim. {{Justified|Trope}} as she is a [[VoluntaryShapeShifter metamorphmagus]].
** [[spoiler:Her son is also a metamorphmagus. Lupin mentions that Teddy had black hair when he was born, and it turned ginger by the time he'd left. Later in the book, he shows someone a picture of Teddy with turquoise hair.]]
* Shifting hair colors is a genetic trait shared by members of Idris' royal family in ''Literature/{{Warbreaker}}''. Hair changes color depending on the person's mood; it turns white when they are scared or nervous, black when they are calm or feeling confident, red when they are angry, and blonde when they are happy. As shown by [[RebelliousPrincess Siri's]] character development, it takes a lot of maturity and restraint to keep one's hair the same color for a long period of time.
* Acheron Parthenopaeus from ''Literature/TheDarkHunters'' series can change his hair color at will. So far it's been black, brown, green, purple, platinum silver, and black with red streaks, among others. {{Justified|Trope}}, since he is [[PhysicalGod an Atlantean god]].
* Danestar Gems in the ''Literature/FederationOfTheHub'' stories always has the same hair colour as her clothes; she uses wigs, which (since she's employed by a detective agency) are usually packed with surveillance gadgets.
* One possible power in ''Literature/{{Xanth}}'' is changing your hair color.
* ''Literature/MySweetAudrina'' by Creator/VCAndrews notes that the women of the Adare (except Vera, a redhead) are born with what they call "chameleon hair", which appears to change colours according to the light.
* Newter of ''Literature/{{Worm}}'' is an orange lizard with AnimalEyes and oft-changing dyed hair.
* In ''Literature/ChildrenOfTheRedKing'', Olivia frequently dies her hair blue, green, purple, etc. In fact, it's a shock when the characters see her with normal brown hair.
* Snorkmaiden from ''Literature/TheMoomins'' can change fur color according to her mood, but this is downplayed in the books and left out of most adaptations altogether.
* Molly Carpenter of ''Literature/TheDresdenFiles'' dyes the ends of her hair during her teenage years, changing colours frequently. Later in the series, she goes back to her natural blond hair.
* Susan, [[IntrepidReporter intrepid]] HotScoop from the ''Literature/ArchieSheridan'' series, changes her hair color with each book.
* The Marquess from ''[[Literature/TheGirlWhoCircumnavigatedFairylandInAShipOfHerOwnMaking The Girl Who Circumnavigated Fairyland in a Ship of Her Own Making]]'' uses magic to change her hair color at will.
* Commander Christine Vale in ''Literature/StarTrekTitan'' often redyes her hair. In ''Over a Torrent Sea'', set on an [[SingleBiomePlanet ocean world]], it's specifically mentioned she dyed it sea-blue to match the mission.

[[folder:Live-Action TV]]
* Beka from ''Series/{{Andromeda}}'' has {{nanomachines}} that can change her hair to any colour she wants.
* Mrs Slocumbe, from ''Series/AreYouBeingServed'', has hair that switches colors frequently. Originally, actress Mollie Sugden dyed her hair different colors, but when it damaged her hair she began to wear varying wigs instead.
* Christine Nelson (from ''Series/{{Degrassi}}'') dyes her black hair bleach blonde in season 8. In season 9 she inexplicably now has red and blonde hair. (To be fair, the character IS a hairdresser. It's likely that she frequently experiments with hair styles.)
* Jool in ''Series/{{Farscape}}'' is a ParodySue with hair that changes color depending on her mood.
* {{Enforced}} in ''Series/TheManyLovesOfDobieGillis''. Dobie's actor (Dwayne Hickman) was made to dye his hair blonde in order to distance him from a previous role. When the show was well established, he was allowed to return to his natural brown hair color; however, at times he had to go blonde again.
* ''Series/BuffyTheVampireSlayer'':
** Oz dyes his hair so often it's difficult to tell what its natural color is.
--->'''Willow:''' Your hair! ...is brown.\\
'''Oz:''' Oh, yeah. Sometimes.
** Anya tends to have a new hair color and style for every episode she appears in.
* You'd be hard pressed to name two episodes where Lillian of ''Series/BoardwalkEmpire'' has the same hair color and style.
* Lucretia from ''Series/SpartacusBloodAndSand'' rotates between her natural hair color and various colored wigs. Later we find out she wears them to honor her old friend Gaia, whose wigs they originally were. TruthInTelevision as the hair fashions were constantly changing in Rome so most noble women used wigs and hair pieces to keep up with them.
* Claudia from ''Series/{{Warehouse13}}'' likes to dye her SkunkStripe in various colors.
* Paige from ''Series/{{Charmed}}'' whose hair is a different colour each season. Black in S4, Red in S5, Blonde in S6 and brown in the last two seasons. Phoebe also had six different hairstyles in the fourth season. In the premiere she was dark blonde but had gone all the way to an almost black hue by the finale.
* Astronema of ''Series/PowerRangersInSpace'' is best remembered for her original purple hair, but it didn't last: she changes its color and style very frequently without comment from anyone else. Mind you, before that, ''Tommy'' was always changing ''his'' hairstyle during his original run. (When it comes to later appearances, he's had the same spiky hair since the 10th anniversary special, breaking the new-season-equals-new-style streak.)
** ''Series/PowerRangersMysticForce'''s Vida has black hair, but there's a streak of a different color that changes from one episode to the next. No indication it's anything other than dye. In the epilogue scenes of the last episode, she's dyed all of her hair pink, evidently having gotten over her initial dislike of her Ranger color.
* ''Series/TheMrPotatoHeadShow'': In the reality TV episode, Queenie starts trying on various wigs, experimenting with different looks. One of them is neon orange!

* Sonika of a Music/{{Vocaloid}} is able to change her green hair color according to her Twitter messages.
* Music/BritneySpears has dyed her hair many colors over the years, though blonde has always been predominant.
* Through the miracle of wigs, Music/KyaryPamyuPamyu has a different hair color ''and'' length almost every time we see her.
* Lead guitarist Mami Sasazaki of Music/{{Scandal}} has had this in spades since about 2012, when the band ditched wearing school uniforms. Since then, her hair has featured blonde, aqua, green, orange, blue, violet, lavender, and silvery colours. More often than not overlaps with MulticoloredHair.
* Music/KatyPerry is constantly changing her hair colors. At various times, it's been black, blond, red, blue, pink, purple and orange.

* During the Hybrid Theory (an album) period, Mike Shinoda of Music/LinkinPark was known for dying his hair red.
* Matt Bellamy of Music/{{Muse}} often dyed his hair various colors during the Origin Of Symmetry period, notably red, blue, and blond.
* This is a common trope in the KoreanPopMusic industry, to the point that it's not unusual for one to change their hair colour (if not style) for each comeback:
** Frequent hair colour changes are especially common with Daesung, T.O.P., and excessively, G-Dragon, all of Music/BigBang. G-Dragon for example has had blonde hair, black hair, pink hair, blue hair, orange hair...
** Music/GirlsGeneration's Sunny frequently changes her hair colors through dying her hair or wearing wigs. Her hair has been in 7 colors (and counting).
** Everyone (except Leo) in Music/{{VIXX}} has hair that changes every once in a while, but Ravi is notable for changing his hair color four times in a six month period.
* Lene wore no fewer than four colored wigs for Music/{{Aqua}}'s "Lollipop (Candyman)".
* Gerard Way of Music/MyChemicalRomance has changed his hair a lot. He's had it black, bleached blond and cut short, then long and bright red for Danger Days.
** He seems to be changing his hair color even more often now that MCR has broken up. In the past few years, it has been red-brown, brown, various shades of blond/yellow, white, black...
* Music/PearlJam guitarist [[http://www.lastfm.com.br/music/Mike+McCready/+images Mike McCready]].
* Music/MsMr's Lizzy changes her hair color a lot, frequently using MulticoloredHair.
* Josh Dun, the drummer of Music/TwentyOnePilots, has been known for sporting a variety of hair colours, re-dyeing his hair on a fairly regular basis. The list of colours so far ranges from bright pink, to purple, to blue, to bluish green, to reddish orange, to his natural brown. See [[http://walkthepilots.tumblr.com/post/100796167380/the-rainbow-of-josh-dun here]] for a few examples.
* Lead singer of Music/{{Paramore}} Hayley Williams. Predominately bright red/orange, but neon greens and blues have been seen.

[[folder:Professional Wrestling]]
* Some Create-a-Wrestler information websites for [[VideoGame/WWEVideoGames WWE games]] tend to list Wrestling/WilliamRegal's hair color as either blonde, brown, or red. He seemingly has KaleidoscopeHair based on the lighting, length, and dampness of his hair. If it's short and slicked back, and he's in a not so well-lit room, it can look [[TallDarkAndHandsome brownish]]. If it's short and slicked back, but the lighting is better, like in a WWE arena, then it can look like a [[EvilRedhead redhead]]. If it's long and dry, and he's in a well-lit room, then it can his natural blond mixed with a [[FirstGrayHair bit of gray]].
* Wrestling/JeffHardy has had numerous colors to his hair.
* [[Characters/WWEDivas The Kat]] liked to have multi coloured hair every week around mid-2000. She alternated between blonde and black hair several times during her stint in Wrestling/{{WWE}} too.

[[AC:[[{{Fora}} Forum Games]]]]
* Fóla Aensland of ''Roleplay/TheOriginOfTheKeys'' can manipulate her hair and eye colors at will. This can be intended to appeal to certain peoples' tastes, but is mostly done just to amuse herself.

[[folder:Video Games]]
* In some scenes of ''VideoGame/FinalFantasyXV'', Noctis' hair looks like a shade of [[YouGottaHaveBlueHair silvery blue]]. Of course, in other scenes his hair seems black or silver, and in the early stages it was meant to be brown.

* In ''Shinkutokimekisempukaku'' (or just ''Shinku!'' for short), Leroy is drawn with a different hair color in every panel. In the first strip where this is evident, the author commentary explains that this is an exaggeration of the real Leroy's habit of frequently dyeing his hair. Similarly, Cary's hat shows a different icon on the front in every panel.
* In ''Webcomic/{{Subnormality}}'', the pink-haired girl switches between neon pink and brown, once in the middle of a conversation with another character. Her explanation: 'I do this a lot'.

* K from ''Webcomic/{{Blip}}'' has hair that varies from brunette to black to pink-ish over the course of the story. At first it just seems like ArtEvolution, until the other characters comment on it.

[[folder:Web Original]]
* ''WebVideo/YuGiOhTheAbridgedSeries'':
