13	->'''Naruto:''' So Kakashi, do you think Sasuke has gotten any stronger?\
14	'''Kakashi:''' Can't you tell; his hair is longer.\
15	'''Naruto:''' What has that got to do with anything?\
16	'''Kakashi:''' Hello? ''Anime/DragonBallZ''.

19	So, your hero has just powered up and you need a way to get this change across visually to your audience. How do that? Well let's see... We have [[PowerGlows glowing with power]]. Check. Ground quaking. Check. [[GrowingMusclesSequence Muscle mass increased by 300%]]. Check. [[ChunkyUpdraft Rapid air displacement]]. Check. But there's still something missing... Ah! Of course! Let's make their hair grow out as well!
20
21	This is the essence of Power Makes Your Hair Grow.
22
23	Now however silly this may seem at a glance, most people will immediately understand that they should now be wary of your hero. It's probably because the sudden appearance of [[WildHair long, unkempt hair can make your hero appear rather feral]] which may be related to [[OurWerebeastsAreDifferent therianthropes]] since they have a habit of growing lots and lots of hair while becoming far more powerful. Also because even if a character can't see the [[BattleAura aura of power]], and everything else signalling that the hero just got stronger, longer hair is a little hard to miss.
24
25	Sometimes "justified" with a SlipknotPonytail coming loose.
26
27	This is primarily an {{Anime}} specific trope, but there are a few non-anime examples out there. {{Magical Girl}}s are known for this.
28
29	Subtrope of AnimeHair and RapidHairGrowth. Sister trope of PowerDyesYourHair.
30	----
31	!!Examples:
32	[[foldercontrol]]
33	[[folder:Anime & Manga]]
34	* In ''Anime/AdolescenceOfUtena'', Utena's drawing her sword from Anthy causes her hair to go from BoyishShortHair to the long hair she sported [[Anime/RevolutionaryGirlUtena in the series]]. Although it's possible that was just some ''very'' CompressedHair being unbraided.
35	* ''Manga/{{AKIRA}}'' has Tetsuo, whose hair gets longer [[WithGreatPowerComesGreatInsanity the more uncontrollable his powers become.]] However, at the end of the manga and the movie, it's inverted when he [[BodyHorror turns into a giant bloblike creature due to his powers becoming so great that they need a larger form to manifest themselves.]]
36	* In ''Manga/AngelSanctuary'', Jibril's hair grows back as soon as Sara's soul left her body, a sign that Jibril has regained her power (albeit in a coma).
37	* ''Manga/{{Bleach}}'':
38	** [[spoiler:Ichigo's Final Getsuga Tensho form]], which may have temporarily made him the strongest character in the entire series, also gave him the longest hair out of any character we've seen so far. Also of note is when Ichigo is [[spoiler:fully hollowfied]].
39	** [[spoiler:Also Aizen after his third hogyoku fusion and beyond.]]
40	** From the same series we have Grimmjow, Nnoitra, and Ulquiorra's release forms.
41	** Power Mullets have practically [[MemeticMutation become a meme]] in the {{Fandom}} due to how much Tite Kubo abuses this trope.
42	* In ''Manga/CrimsonSpell'', one of the ways you can tell when Prince Vald's transformation into his SuperPoweredEvilSide is more advanced than usual is when it causes his hair to grow out. He has to re-do his own ImportantHaircut after such a transformation in the third volume of the manga.
43	* In ''Manga/CuticleDetectiveInaba'', the werewolves' transformations almost always grow their hair to ridiculous legnths. In Haruka's case, the hair growth alone tires him out so much that he faints immediately after.
44	* {{Inverted\|Trope}} in ''Literature/DateALive''. When Kurumi activates her powers, it removes her bangs, making her left eye visible.
45	* In ''Anime/DayBreakIllusion'', this is the main physical effect of [[MagicalGirl transforming]]. There are some other changes, mind, but getting much bigger hair is both universal and the most striking effect.
46	* In ''Anime/DigimonAdventure'', a few of the Digivolutions result in the Digimon gaining [[BishonenLine more human forms]] and long hair as a result. Birdramon to Garudamon, Gatomon to Angewomon, Patomon to Angemon are examples.
47	* ''Anime/DragonBallZ'':
48	** Super Saiyan 3 is the TropeCodifier. The first two levels change hair color and add lightning bolts to your aura, respectively. The third level increases your hair volume ridiculously. {{Lampshade\|Hanging}}d by Babidi when Goku shows him and Buu the first two levels of Super Saiyan: "You've changed your hair, so what?"
49	** This drew a lot of jokes questioning what Raditz (who already has ridiculously big hair) or Nappa ([[BaldOfEvil bald]]) would look like if they achieved Super Saiyan 3. These questions were answered in 2017 by ''VideoGame/DragonBallHeroes'': [[https://vignette.wikia.nocookie.net/dragonball/images/6/6b/Dragon_Ball_Heroes_Super_Saiyan_3_Raditz.jpg Raditz's]] already long hair becomes so long it reaches past his feet, while [[https://vignette.wikia.nocookie.net/dragonball/images/5/5d/SSJ3.jpg Nappa]] remains bald but his goatee turns into a bushy beard. ''VideoGame/DragonBallXenoverse2'' reveals that Nappa remaining bald is due to his baldness being natural because of his age, as bald Saiyan Time Patrollers get the form's iconic long hair indicating shaved heads.
50	** Subverted in the ''[[Anime/DragonBallZBattleOfGods Battle of Gods]]'' movie, where Super Saiyan God, a new form that is beyond even Super Saiyan 3, simply gives Goku his normal hairstyle (except it's red).
51	** Even characters who don't have hair at all see shades of this trope, such as Super Buu, whose big... [[BuffySpeak floppy... head... thingy]] just kept growing longer and longer each time he absorbed someone.
52	** Gohan's first Super Saiyan form simply dyes his hair gold -- it doesn't grow and point upwards until he goes Super Saiyan ''2'' against Cell. Similarly, Trunks' hair gets a lot wilder when he goes Super Saiyan Third Grade.
53	** ''Anime/SuperDragonBallHeroes'': Chronoa and Aeos both look like children with short hair. They can both enter a SuperMode called Time Power Unleashed that gives them adult bodies and waist length hair.
54	** ''Anime/DragonBallSuper:SuperHero'': Gohan's new form also causes his hair to grow longer, but not to the extent of Super Saiyan 3.
55	* In ''Anime/FlipFlappers'', both Cocona and [[spoiler:Yayaka]]'s shoulder-length hair become waist-length as magical girls. Averted with Paprika whose hair remains the same length when transformed and exaggerated with [[spoiler:Mimi]] whose waist-length hair grows down to floor length [[TransformationSequence when she evokes "Flip Flapping"]].
56	* In ''Manga/{{Hellsing}}'', Alucard's hair grows and retracts according to his power levels (it's fairly short in normal situations, but well past waist-length when dealing with the likes of the Valentine Brothers).
57	* In ''Manga/HunterXHunter'', Gon's hair grows when he [[spoiler:becomes ultrapowerful to defeat Pitou.]] Afterwards [[spoiler:he loses his Nen abilities completely as a side effect, but his hair remains long.]] It might be worth nothing that [[spoiler:not only Gon’s hair grows but his whole body. Before he had the stature of a child and afterwards he has the body of an adult. Neferpitou assumes that what Gon did is age himself to a point where he can defeat them so that’s presumably why his hair grew.]]
58	* ''Manga/JoJosBizarreAdventure'':
59	** ''Manga/JojosBizarreAdventurePhantomBlood'': Immediately after becoming a vampire, [[BigBad Dio]]'s short hair becomes a shoulder-length and spiker mules.
60	** ''Manga/JojosBizarreAdventureStoneOcean'': [[SinisterMinister Enrico Pucci]] grows a ponytail when [[spoiler:his Stand evolves to Made in Heaven, its final form]].
61	* ''Anime/{{Kamichu}}'': Extreme example. The main character goes from a sort of pageboy cut to somewhere past Rapunzel when using her goddess powers.
62	* [[AsianFoxSpirit Tomoe]] in ''Manga/KamisamaKiss'' normally has a short pageboy-style hair cut. But when the power limiter Mikage placed on him is removed, his hair grows to the point that it drapes over his shoulders and flows down most of his back.
63	* ''Anime/KillLaKill'': When Ryuko equips Senketsu-Kisaragi, her hair seems to puff out to a longer length than usual.
64	* ''Literature/KyoKaraMaoh'': In the anime only, when Yuri taps his Demon powers, his hair suddenly grows and he seems to gain a more mature air. It reverses back to his boyish mop once the effort is done.
65	* Rio of ''Manga/MagicalGirlLyricalNanohaVivid'' has her short, tomboyish hair growing all the way down to her waist whenever she accesses her [[OlderAlterEgo combat form]].
66	* In ''Manga/{{Naruto}}'', all of the characters with a [[OneWingedAngel Cursed Seal]] have their hair get at least slightly longer when they go into Stage 2, except Jugo, which is funny considering the Cursed Seal ''comes from him''. Jugo's [[SuperPoweredEvilSide psycho persona]] has a considerable amount of control over his transformation; considering there'd be no actual benefit to changing hair, it doesn't. By comparison, the others have to essentially give in to the seal to actually use it.
67	* ''Manga/NegimaMagisterNegiMagi'': Negi Springfield during his lightning-god form. His hair becomes as long as he is tall... sort of, as it turns into energy/lightning about halfway down.
68	* ''Manga/OnePiece'':
69	** When [[spoiler:Carrot enters her Sulong form under a full moon]], her hair changes from short and blonde to pure white and longer than she's tall. This also applies to other members of her race.
70	** [[spoiler:Luffy's]] hair appears to grow longer and wilder when he's using [[spoiler:Gear Fourth's Snake Man form]] but it's nowhere near as exaggerated as the above example.
71	* Inverted in ''Manga/OnePunchMan''. Saitama did so much muscle training that all his hair fell out and he's permanently bald. A few other characters, like Darkshine, had the same thing happen to them.
72	* In ''Manga/PokemonAdventures'', when [[spoiler:Caitlin]] loses control over her powers, her hair grows drastically in length and starts attacking people.
73	* In ''Manga/{{Pretear}}'', [[spoiler:Mikage]]'s hair grows well past floor length ''while she's floating'' when she transforms into the Princess of Disaster. It is shown in a later scene that she is actually quite short in proportion to Sasame. The hair all disappears in the finale when [[spoiler:Sasame dies and she returns to her normal human-Takako form.]]
74	* In every season of ''Anime/PrettyCure'', whenever the Cures transform, most of the time their hair grows and changes color.
75	** Zigzagged in ''Anime/FutariWaPrettyCure'': Cure Black and Cure White's longer hair is hardly notable, but when Shiny Luminous arrives in ''[=MaX=] Heart'', her mid-length braid turns into two massive pigtails.
76	** In ''Anime/YesPrettyCure5'', Komachi and Karen's elbow-length hair grows down to their knees when they become Cure Mint and Cure Aqua.
77	** In ''Anime/FreshPrettyCure'', Love's short pigtails grow down to her waist as Cure Peach.
78	** Some Cures also get different hairstyles (for instance, [[Anime/HeartcatchPrettyCure Tsubomi]]'s red [[GirlishPigtails pigtails]] become an extra long pink ponytail whenever she transforms into Cure Blossom).
79	** In ''Anime/SuitePrettyCure'', Hibiki, Kanade, and Ellen's waist-length hair all grow down to their knees as Cure Melody, Cure Rhythm, and Cure Beat, while Ako's chin-length hair grows down to her ankles.
80	** Transforming into a SuperMode can then make a Cure's hair grow a second time. ''Anime/SmilePrecure'' goes even further, as the girls get one instance of hair growth when transforming, a second when changing into [[SuperMode Princess Form]], and a third when changing into [[EleventhHourSuperpower Ultra Form]].
81	** In ''Anime/DokiDokiPrecure'', Mana's chin-length hair grows to her thighs as Cure Heart.
82	** In ''Anime/HappinessChargePrettyCure'', Megumi's shoulder length hair grows down to her ankles as Cure Lovely.
83	** In ''Anime/GoPrincessPrettyCure'', Haruka's chin-length hair grows down to her waist as Cure Flora.
84	** In ''Anime/MahoGirlsPrecure'', Mirai's chin-length hair grows down to her thighs as Cure Miracle.
85	** In ''Anime/KiraKiraPrecureALaMode'', Ichika's bicep-length pigtails grow down to her waist as Cure Whip.
86	** In ''Anime/HugttoPrettyCure'', Hana's shoulder-length hair grows down to just above her hips as Cure Yell. Interestingly, her poorly-trimmed bangs don't change at all.
87	** In ''Anime/StarTwinklePrettyCure'', Hikaru's shoulder-length pigtails grow down to her knees as Cure Star.
88	** In ''Anime/HealinGoodPrettyCure'', Nodoka's chin-length bob turns into a waist-length crown as Cure Grace.
89	** In ''Anime/TropicalRougePrettyCure'', Manatsu's shoulder-length ponytail grows down to the ground as Cure Summer.
90	** In ''Anime/DeliciousPartyPrettyCure'', Yui's bicep-length hair grows down to her thighs as Cure Precious.
91	** In ''Anime/HirogaruSkyPrettyCure'', Sora's tiny side-ponytail grows into floor-length pigtails as Cure Sky.
92	* Inverted in ''Anime/PrincessTutu''; when Ahiru transforms into Princess Tutu, her hair becomes shorter, going from a long braid to a neat bob haircut.
93	* In ''Anime/PuellaMagiMadokaMagica'', Madoka's hair falls to just below the shoulders when it's let out of the pigtails. As [[spoiler:Goddess Madoka]], however, she has long hair. ([[AllThereInTheManual According to the animators, the ends of it should never be depicted onscreen]].)
94	* In ''Literature/ReMonster'', Goburou fits this. [[spoiler:His hair grows as he evolves from a [Hobgoblin: Subspecies] to an [Ogre: Rare Variant].]]
95	* ''Anime/SailorMoon'':
96	** While Usagi already had long hair, in the manga and ''Anime/SailorMoonCrystal'' it grew to absolutely unmanageable lengths after she became the Moon Princess for the first time. She locked herself in her room for several days as a result, and the Senshi had to cut it short for her.
97	** Also Lampshaded later on by [[EnemyWithin Mistress 9]] [[spoiler:after she takes full possession of Hotaru]] while complaining about how [[FridgeLogic inconvenient super-long hair actually is]]. Note that her hair invariably trails off-panel in every shot she's in. In the [[Anime/SailorMoon first anime]], however, not only does she not complain about her hair being inconvenient, ''[[PrehensileHair she ties her enemies up with it]]''.
98	* Both Hakkai and Goku support this theory in ''Manga/{{Saiyuki}}'' when they remove their power limiters.
99	* ''Anime/{{Shuffle}}'': When [[spoiler:Asa finally uses her magic to save Rin's life]] in the final episode. It shows her later with her hair braided down to her hips.
100	* ''Anime/TenchiMuyo'': The monk Gohgei grows long sleek black hair every time he transforms into his Gargutian warrior form, and it stays when he transforms back. He always shave it off, though - partly because he's a monk, but also because he wants to hide his monstrous appearance from his ward Asahi. [[spoiler:She's known about it ever since they met. She actually has no idea he's trying to hide it.]]
101	* In ''Anime/UmiMonogatari'', both Marin and [[spoiler:Urin]] get this when transformed. Kanon just gets IdiotHair and a different color/shape to her hair.
102	* When Ushio of ''Manga/UshioAndTora'' uses the power of the beast spear, it usually results in him growing hair past his legs. Should he draw on a remarkable amount of that power? Bring a comb (seriously, it's the only way to bring him back).
103	* Happens to [[spoiler:Yuuki Cross]] from ''Manga/VampireKnight'', after [[spoiler:her vampire powers are unsealed by Kaname]].
104	* Happens in some Primagistas in ''Anime/WacchaPriMagi'':
105	** Matsuri’s medium hair becomes longer in Primagi form, and Hina becomes slightly longer while tied in ponytail, while Lemon’s drill buns apparently becomes longer with more curls in her hair. Jennifer also gains longer hair that almost reach her knees.
106	** Inverted with Amane, as her hair becomes shorter in Primagista form.
107	* While this happens in ''Manga/YozakuraQuartet'' whenever Akina uses his tuning ability, it's not as drastic as some of the other examples here.
108	* ''Anime/YuGiOh'' has somewhat of an example. Bakura's hair becomes much 'poofier' when he becomes his evil alter ego. When Marik goes evil it his hair ''stands straight up''. Yugi/Dark Yugi is a smaller example, with some of his yellow bangs spiking up. He also gets more 'points' and more layers to his hair.
109	* ''Manga/YuYuHakusho'': Near the end of the Sensui arc, [[spoiler:Yusuke awakens from near death as a half-demon]] and has long, unkempt hair down below his waist, among other cosmetic changes. (It doesn't stick, though, as he asks [[spoiler:Kurama]] to cut it back short. Notably, it happened around a year '''before''' the [=SSJ3=] in ''Manga/DragonBall'' was introduced.
110	[[/folder]]
111
112	[[folder:Comic Books]]
113	* Anytime ''ComicBook/BazookaJules'' activates her powers her pigtails grow from barely reaching her ears to all the way to the floor and then some. It's not just for show as she can use her [[PrehensileHair hair to attack, or wrap around her enemies.]]
114	* When Lucy Weber becomes the new ''ComicBook/BlackHammer'', her modest hair bun grows into an afro bun bigger than her head.
115	* In issue 4 of the ''ComicBook/DisneyKingdoms'' series ''[[ComicBook/FigmentDisneyKingdoms Figment]]'', Blair overcomes his fears while trapped in the Nightmare Nation and becomes the Dreamfinder, growing his iconic beard before bringing Figment back into existence.
116	* When David Landers of ''ComicBook/DP7'' gained his powers it also came with RapidHairGrowth giving him excessive body hair and necessitating a shave of a, relative to his height, foot-long beard and locks every day. [[InvertedTrope Ironically]] it also made him bald on the top of his head.
117	* This is a common side effect of [[RadiationInducedSuperpowers gamma radiation]] in the ''Franchise/MarvelUniverse'':
118	** Doc Samson has long hair every time he gets into his power phase.
119	** It also seems to happen to ComicBook/SheHulk -- since with her height increase her hair would have to be floor-length in her petite normal form otherwise. Definitely applies in [[WesternAnimation/TheIncredibleHulk1996 the 90s cartoon]], where normal Jennifer has bobbed hair.
120	** Of course, there's ComicBook/TheIncredibleHulk himself. In MediaNotes/TheBronzeAgeOfComicBooks, the Hulk had a shaggy mop and Banner's hair was usually neatly trimmed. In the [[MediaNotes/TheModernAgeOfComicBooks Modern Age]], the reverse is often true: Hulk is often crew-cut, and Banner occasionally drifts close to [[EinsteinHair Mad Scientist Hair]], particularly when he's in TheMadnessPlace.
121	** In an amusing reversal, the Red Hulk has a mustache in his unpowered form, which ''vanishes completely'' when he [[HulkingOut powers up]]. Originally, of course, this was to keep his identity a secret from the readers.
122	* Another reversal exists in [[Characters/MarvelComicsCarolDanvers Carol Danvers]] during her time as [[SuperMode Binary]]. DependingOnTheArtist she's depicted with either FlamingHair or a corona of energy crowning a shaven head.
123	* In ''ComicBook/{{WITCH}}'' the hair of the Guardians of Kandrakar tends to grow when they change in their Guardian forms, in three different variants:
124	** In the original Will's remained normal, Irma and Taranee's grew somewhat (with Taranee's having a massive change in hairdo) and Cornelia and Hay Lin (whose hair normally reach their lower backs) got their hair close to their calves.
125	** With the New Power arc Will's hair grows a bit, Irma and Taranee get full-on long hair, Hay Lin's hair remains the same length of the previous transformation but increases in quantity and gets in a new and more complex hairdo, and Cornelia's hair remains exactly as in her original transformation.
126	** Will's ability to glamour includes ''literally'' growing her own hair and wearing it in different styles, as she demonstrated once.
127	[[/folder]]
128
129	[[folder:Fanfiction]]
130	* In the ''Franchise/LyricalNanoha'' fanfic ''Fanfic/{{Infinity}}'', Arf's hair grows about a foot in length when using 50% of Fate's Linker Core instead of the usual 5. She doesn't question it since she's seen several shows on Earth that abide by this rule (the aforementioned Dragon Ball Z likely among them).
131	* Fanfic/TheKedaboryVerse:
132	** ''Fanfic/MapleSugarPrettyCure'': [[WesternAnimation/TurningRed Mei]]'s modest bob turns into long pigtails when she becomes Cure Panda.
133	** Inverted for [[Anime/SmilePrecure Haru]]/[[SailorEarth Cure August]] in ''Fanfic/TwinklingInTheDark''; her hair gets shorter when she transforms.
134	* Fanfic/KhaosOmega uses an added variant in the form of a serum created by Anise in her youth that's to be infused into someone's hair. The original variant of the serum includes an effect called "Elemental Match" where contact with the correct element skyrockets the hair length by absorbing the element; Anise accounted for possible financial issues regarding blue-haired individuals with it infused and implemented a user-controlled limiter for them specifically. An upgraded variant, created by Io Martinez, enhances Elemental Match to kick in on contact with any kind of energy, which can be combined with a variant that skyrockets the effect's length multiplier created by Kandyce.
135	* ''Fanfic/ThanksButNo'': When Nino Lahiffe uses the Bee Miraculous to become Mellifera, his buzzcut grows into a ponytail of dreadlocks to hold the comb in place.
136	[[/folder]]
137
138	[[folder:Films -- Animation]]
139	* Inverted in ''WesternAnimation/{{Tangled}}''. Rapunzel grows out her hair because her hair would lose its powers if she cut it.
140	* ''WesternAnimation/WonderWoman2009'': Part of Ares' OneWingedAngel form is his hair going from short and close-cropped to ankle-length.
141	[[/folder]]
142
143	[[folder:Films -- Live-Action]]
144	* ''Film/DemonOfTheLute'' -- a bald guy goes full-on troll doll about [[https://www.youtube.com/watch?v=5e1rs-5QRuw two minutes in]].
145	* In ''Film/ScottPilgrimVsTheWorld'', Todd's psychic powers make his hair spike when in use. Upon losing them for violating his veganity (long story), his hair sinks back down over his head, limply.
146	[[/folder]]
147
148	[[folder:Literature]]
149	* The healing rings in the ''[[Creator/BrandonSanderson Infinity Blade]]'' novels work by speeding up the body's natural healing processes, so each use [[CastFromLifespan ages the hero about six months]] - and causes him to grow about six months' worth of hair and beard.
150	[[/folder]]
151
152	[[folder:Live-Action TV]]
153	* Happens a couple of times in ''Series/{{Charmed\|1998}}'':
154	** Paige's shoulder-length hair grows down to her waist when she is turned into a wood nymph.
155	** Phoebe's hair turns blonde and goes down to the floor when she is turned into a Greek Goddess (based on Aphrodite).
156	** Phoebe's hair goes blonde again and becomes longer (though it's up in a bun) when she is turned into a genie. It's meant as a ShoutOut to ''Series/IDreamOfJeannie''.
157	** Again when Phoebe becomes a banshee her hair becomes waist length and white.
158	** When Wyatt turns into his evil future self, his short hair grows to shoulder length.
159	** Leo's evil self has longer SpikyHair while Chris's evil self has a ponytail.
160	* Most of the Riders from ''Series/KamenRiderExAid'' have SCULPTED AnimeHair on their helmets, most especially the [[TheHero titular Rider himself]]. So when he gets the franchise-standard SuperMode, not only is it extremely [[GoldenSuperMode gold]] and [[EverythingsBetterWithSparkles sparkly]], his helmet's hair grows into long tendrils...that are [[PrehensileHair prehensile]]. Comparisons to Super Saiyan 3 and, appropriately given the show's video game theme, Super Sonic immediately sprouted upon the design's reveal.
161	* Colin Robinson of ''Series/WhatWeDoInTheShadows2019'' is a WhiteCollarWorker and [[OurVampiresAreDifferent energy vampire]] who is [[DaywalkingVampire unharmed by sunlight]] and feeds by [[{{Troll}} annoying]] and/or [[TheBore boring]] people. When he got a promotion at the office, his ability to feed dramatically increased (more people were forced to listen to him) and his male-pattern baldness was suddenly replaced with full, thick hair, which was subsequently replaced by a [[ForeheadOfDoom bulbous]] [[MyBrainIsBig head]].
162	[[/folder]]
163
164	[[folder:Manhua]]
165	* In ''Manhua/InfinityGame'' when Hai An transforms into a paladin his hair grows extremely long. This only happens to him and nobody has any idea why.
166	* ''Manhua/IronLadies'': Siyun's hair grows when using the Dragon Empress' powers.
167	* ''Manhua/MyCultivatorGirlfriend'': Thanks to Muzi Li's power amplifying inside him to save her from Rú Yuè, Ma Yingxiong's hair grows to waist length.
168	[[/folder]]
169
170	[[folder:Manhwa]]
171	* ''Manhwa/AngelDiary'': Dong-Young's short, boyish hairstyle grows out to long, flowing tresses when the seal on her power is released.
172	* ''Manhwa/FaeriesLanding'': The faeries' hair usually appears even longer when they are all powered up.
173	[[/folder]]
174
175	[[folder:Mythology and Religion]]
176	* Inverted in the story of [[Literature/TheBible Samson]]. He was blessed with super strength so long as he continued to grow his hair out and lost his divine powers once it was cut.
177	[[/folder]]
178
179	[[folder:Pinball]]
180	* ''Pinball/DrDude''[='=]s hair gets noticeably larger after his transformation.
181	[[/folder]]
182
183	[[folder:Video Games]]
184	* ''VideoGame/ANNOMutationem'': Whenever Ann activates her SuperMode, her hair also lengthens once she awakens it.
185	* ''VideoGame/AzureStrikerGunvolt2'': Zonda's hair lengthens dramatically in her transformed state, to the point it becomes floating hair.
186	* ''VideoGame/DragaliaLost'': Euden’s [[spoiler:Bondforged Form turns his hair long, making it look similar to [[PosthumousCharacter Alberius’s]] hair.]]
187	* In the Eternal Calm prologue to ''VideoGame/FinalFantasyX2'', Yuna is shown in her default outfit from the first game. But when Rikku presents her with a Garment Grid and she spherechanges into the gunner dressphere, Yuna instantly gains a a braid that goes all the way down to the floor.
188	* Giana of ''VideoGame/TheGreatGianaSisters'' grows a punk hairdo when becoming super.
189	* It seems that anyone who becomes a [[PhysicalGod Herrscher]] in ''VideoGame/HonkaiImpact3rd'' ends up with their hair growing out, with the noticeable exception of [[BlowYouAway Wendy]]. The most notable examples are [[spoiler:Kiana, Bronya and Mei as the Herrschers of the [[PowerOfTheVoid Void]], [[ThePowerOfCreation Reason]] and [[ShockAndAwe Thunder]] respectively]].
190	* Several characters in ''VideoGame/InazumaEleven 2'' get longer, often wilder hair while under the effects of [[spoiler:[[MagicMeteor the Aliea Meteorite]]]].
191	* Yun from ''VideoGame/ManaKhemia2FallOfAlchemy'' has a pretty short cut in his everyday form, but it grows out along with his [[HornedHumanoid horns]] and [[WolverineClaws claws]] when he enters battle, and even more when he uses his LimitBreak.
192	* ''Franchise/{{Pokemon}}'': When Ampharos Mega Evolves, it gains gorgeous white flowing hair, giving it the nickname "Amphabulous".
193	** The Mareep line as a whole inverts this since Flaafy has noticeably less hair than Mareep, and Ampharos (outside of its Mega Evolution) is completely devoid of hair.
194	** Lucario doesn't get hair, but he gets a gigantic fluffy tail.
195	** A strange case with Mega Mewtwo Y, who doesn't get hair but its tail moves to the top of its head, looking like hair.
196	** Mega Altaria looks like a bird piled with cotton. It even has a hat made of cottony stuff.
197	* ''VideoGame/ShinMegamiTenseiV'': The Protagonist's relatively short hair becomes a lot longer once he becomes The Nahobino.
198	* When ''VideoGame/StreetFighterV'' newcomer Necalli activates his [[SuperMode V-Trigger]], his hair turns a fiery red and stands on end.
199	%% ZCE * [[spoiler:Taboo Sho Minamimoto]] in ''VideoGame/TheWorldEndsWithYou''.

203	* ''Franchise/{{Danganronpa}}'': After undergoing the Hope Cultivation Program, a surgical operation which granted him [[AllYourPowersCombined every known Ultimate talent in existence]], Izuru Kamukura has hair that reaches to the floor. Compare that with the very short hair of his [[OrdinaryHighSchoolStudent talentless pre-surgery identity]], [[spoiler:[[TomatoInTheMirror Hajime Hinata]]]]. The entire process took around 6 months, (partly) justifying how his hair grew so long, and also [[DeathOfPersonality removed his emotions and personality]] to make room for more talent, justifying why he keeps it that way: he just doesn't care enough to bother cutting it.
204	* [[spoiler:Koujaku]] from ''VisualNovel/DramaticalMurder'' when his SuperPoweredEvilSide takes control of his body. In the bad end, [[PowerDyesYourHair his hair even changes color]].

208	* ''Webcomic/BowsetteSaga'': When Chompy powers up by eating her own chain, her hair changes from a bob to waist-length.
209	* ''Webcomic/ElGoonishShive'':
210	** Susan's hair grew to knee-length when her magical power and angst received a major spike. She cut it later back to its usual length, presumably with Justin's help.
211	** It also seems to be happening to Nanase. Despite having [[BroughtDownToNormal burned out her magic,]] her hair is growing back rapidly as compensation. Tedd theorizes that this is because she is still generating magic power as normal, but doesn't have a way to use it, so her body is expending it by making her hair grow since that's a safe outlet.
212	** This also happens to anyone who is zapped with the V5 beam.
213	* ''Webcomic/TheFan'' has Pete, a character with short trimmed hair. His hair grows to ridiculous lengths and turns gray (along with his skin turning brown) when his earth-based powers are activated. When he reverts back to normal, he simply sheds it.
214	* ''Webcomic/GunnerkriggCourt'': While merely due to ArtShift, Antimony's hair [[http://www.gunnerkrigg.com/?p=678 extends and flows over the page]], even joining with her head at multiple points on the page, when she uses her [[AmplifierArtifact blinker stone]].
215	* In ''Webcomic/{{Namesake}}'', Elaine's hair which she wears in a bob grows long enough to drag on the floor within moments as [[spoiler:her muse powers activate]]. She's anything but happy about this, as [[SurprisinglyRealisticOutcome she's constantly tripping over it]].
216	* ''Webcomic/OnePunchMan'': Garou's hair grows outwards wildly, and becomes more horn-ish as he fights and becomes stronger until he transforms into a mysterious being and his hair becomes real horns. He goes bald in exchange, though.
217	* In ''Webcomic/TheOrderOfTheStick'', Vaarsuvius' hair grows from a bob to waist-length when they gain temporary ultimate arcane power by [[spoiler:making a DealWithTheDevil.]] It stays long after the power wears off, causing them to wear their hair in a ponytail.
218	* This happened to Anne Onymous of ''Webcomic/TheWotch'' when [[spoiler:she sees Robin critically injured and goes into an UnstoppableRage]].

222	* In ''WesternAnimation/{{Amphibia}}'', the full power of [[spoiler:the Calamity stone]] causes the twigs in Anne's hair to grow and her bushy hair to stand on end.
223	* Parodied in ''WesternAnimation/CodenameKidsNextDoor'''s [[AffectionateParody teasing]] of the Super Saiyan transformation, where Numbuh Four gains a 4-foot hairstyle but doesn't actually become stronger, and is promptly [[CurbStompBattle kicked away like a soccer ball]].
224	* In ''WesternAnimation/DrDimensionpants'', Kyle's hair goes from being short and light ginger to a tall black mohawk with a white lightning bolt-shaped streak whenever he becomes his alter-ego. As well as this, he also gains a mustache.
225	** In one episode, his pants get mixed up at a dry cleaners with a skirt belonging to his female counterpart Dr Dimensionskirt, forcing him to don it in battle and grows long wavy brown hair as a result.
226	* ''WesternAnimation/DoraTheExplorer'': When Dora becomes [[spoiler:a princess]] in fairytale adventures, her hair does this, [[spoiler: with assistance of a magic brush]].
227	* In ''WesternAnimation/GreenLanternTheAnimatedSeries'', when Carol Ferris becomes Star Sapphire her new costume also comes with two extra feet of hair. It even goes away she takes the ring off.
228	* ''WesternAnimation/TheIncredibleHulk1996'': Jennifer Walters' short brown hair becomes long and green when she becomes She-Hulk.
229	* All three princesses in ''WesternAnimation/LoliRock'' get noticeably longer and brightly colored hair while in their [[FrillsOfJustice Magical Outfits.]]
230	* When [[WesternAnimation/MiraculousLadybug Ladybug]] unlocks a new power early in Season 4, it also gives her a more mature costume upgrade that includes making her pigtails slightly longer and tapered.
231	* ''WesternAnimation/MyLittlePonyFriendshipIsMagic'':
232	** Princess Luna, when she appears in the second season, has her mane and tail much longer (not to mention flowing and ethereal) than in her de-powered form seen at the end of the pilot episodes. That's nothing to say of [[SuperpoweredEvilSide Nightmare Moon]], whose mane was long enough to form a city-hall-filling funnel cloud ''[[SwirlyEnergyThingy made of stars]]''.
233	** In ''[[Recap/MyLittlePonyFriendshipIsMagicS4E26TwilightsKingdomPart2 Twilight's Kingdom Part 2]]'':
234	*** When the Mane Six [[spoiler:are bestowed the Rainbow Power]], it has this effect.

238	* Happens when a character enters their Turbo form in ''WesternAnimation/OKKOLetsBeHeroes''. This holds true for all five Turbo forms seen in the series; for some of them, their hair only grows a little longer, while for others it grows much more, but in all cases, it grows much more wild-looking and more like AnimeHair.
239	* In perhaps the ''darkest'' iteration of this trope, in ''WesternAnimation/TheOwlHouse'' episode "Thanks To Them", [[spoiler:Belos's DemonicPossession of Hunter causes Hunter's short, spiked hair to grow out to shoulder-length in an instant, and it stays that way even after Belos gets thrown out of his body. Earlier in that same episode, Hunter actually allowed it to grow past his shoulders naturally, but when he saw that long hair made him resemble Belos and Caleb too much, he had a panic attack and [[ImportantHaircut chopped it all off]].]]
240	** [[spoiler: In the GrandFinale, after being brought back to life by the Titan due to her HeroicSacrifice, Luz returns in her [[SuperMode Titan form]], which makes grow her usual short haircut in an unruly mane that reaches her shoulders. Even Raine says that she looks “fluffier” in said form]].
241	* ''WesternAnimation/ThePowerpuffGirls1998'':
242	** The Rowdyruff Boys when [[spoiler:they're brought back from the dead.]]
243	** Sedusa's power comes partly from her PrehensileHair, which the girls cut off when they've defeated her. She later gets her hands on a powerful artifact that gives her more power -- and also grows her hair back in the form of snakes.
244	* The power of [[WhatTheHeckIsAnAglet aglet awareness]] made one guy's hair grow back in the ''WesternAnimation/PhineasAndFerb'' episode "Tip of the Day".

246	* In ''WesternAnimation/StevenUniverseFuture'' episode "Fragments", Steven's new Pink form has longer hair that sticks out in the front like a messy pompadour.
247	* Raven from ''WesternAnimation/TeenTitans2003'' when Slade rips off her costume and activates her birthmarks. She's seen in the next scene [[StatusQuoIsGod trimming it back down to its normal length]]. Her hair also grows long when she powers up in the Season 4 finale.
248	* In ''WesternAnimation/WinxClub'', Tecna's pixie cut hair grows to be shoulder-length in her Enchantix form.
249	* As in the comic, there's a slight length change whenever the heroines of ''WesternAnimation/{{WITCH}}'' take up their Guardian forms. Most notably, Cornelia's hair grows more than usual (and not just thatù) in "N is for Narcissist" when she ends up wielding all five elemental powers.

253	* The closest thing there is to this is when weak animals suffering a severe protein deficiency or a deadly sickness will start loosing their fur as a result and it not grow until they regain their vitality.
