* A late episode of ''{{K-On}}!'' has Yui accidentally chop her bangs very short while trying to trim them, and they go back to their usual length in the next episode. [[BrickJoke However, a bonus episode that chronologically took place shortly after this incident]] [[SubvertedTrope shows her with her hair still cut short]].

* In ''{{Eureka Seven}}'', Eureka lost a significant amount of hair in episode 19 and eventually has her hair grown back in an instant by Sakuya in episode 41. She even reverts back to her very original hairstyle by the final episode.

* In ''Manga/FairyTail'', Juvia (who has shoulder-long hair) and Freed (whose hair reaches his lower back) both cut their hair short - Juvia when she joins the titular guild and Freed after the Fighting Festival (in order to atone). When Freed is seen again one arc later, his hair is suddenly very long again. When Juvia finds out, after the Edolas arc, that [[ParallelUniverse Edo-gray was in love with Edo-Juvia]], she suddenly grows her hair long again (she apparently thought it was her hairstyle that he was in love with).

* In ''Manga/{{Bleach}}'', Tsukishima cuts off the majority of one of Riruka's very long pigtails in a CloseCallHaircut. The next time she is seen the entirety of the ponytail is back and in pristine condition.

Subtrope of RapidHairGrowth. Contrast with ImportantHaircut, ExpositoryHairstyleChange, and CloseCallHaircut. Compare ResetButton and BeautyIsNeverTarnished but just for hair.

* In the official Doujinshi Anthology of ''VisualNovel/AceAttorney'', main character Phoenix Wright (who is known for having had Anime hair ever since he was ''born'', despite not using hairgel or the likes) is shown with wet hair in two instances, which reveals that he's ''literally'' an "Instant {{Bishounen}}, Just Add Water". How to get his hair back to it's usual shape? ''Shake his head twice and apply the hairdryer for aproximately two seconds''. A very dumstruck Edgeworth compared it to "Shape Memory Alloy".

** While her hairstyle is very simple, the same goes for Laura, as well. Highlighted in ''ComicBook/AllNewXMen'' when she's completely bald after escaping torture by the Purifiers, then over the next few panels of the following issue it visibly regrows to its normal length.

* Jessie from ''Anime/{{Pokemon}}'' tries to capture a Seviper in one episode. She does badly...until Seviper bites off a piece of her hair. After Jessie gives it a NoHoldsBarredBeatdown, her hair returns to normal in a few seconds.

* First lampshaded and then subverted in ''Series/TheColbertReport''; after StephenColbert got back from the [[CrowningMomentOfAwesome USO shows in Iraq]], he first wore an over-the-top fake wig and since has gotten increasingly blacker stubble.

* Inverted in ''WesternAnimation/TotalDramaIsland'', where Heather's hair is shaved at the end of the first season and she remains bald throughout the entire second season. This is unrealistic for the opposite reason: after several weeks pass, she really should have at least some hair again.

* In ''MyLittlePony'', during "The Glass Princess" story, a few of the ponies are captured and their manes are cut off. The hair grows back instantly, making the {{mooks}} who cut it off goggle in amazement. ([[RealLifeWritesThePlot This was done because the writers were aware that the animators couldn't be relied on to draw the ponies with their manes cut for the rest of the serial.]])
** Also occurs in ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' after Rarity [[ImportantHaircut chops off most of her tail]]. In this case, instead of growing back instantly, it only reverts to its normal length after invoking [[ThePowerOfFriendship The Power Of]] [[AWizardDidIt Magic]].

* On ''{{Jimmy Two-Shoes}}'', Jimmy gets his hair cut off thanks to [[AmusementParkOfDoom a deadly rollercoaster]] Lucius had strapped him into. The next scene it was back.

* In ''DevilMayCry 3'', during the first fight with Vergil, it's raining and Vergil's normally spiked-back hairdo looks more like Dante's. After you, uh, "win", he makes a motion with his hand to slick back his hair with his hand and his hair goes back to normal.

* An episode of ''MartinMystery'' had Diana end up totally bald due to a bad dye job. By the next episode, her hair is back.

* Justified in ''Webcomic/OrderOfTheStick'', when [[spoiler: Haley]] uses a magical hair growth treatment.

* Mocked in the webcomic ''FriendlyHostility''. Fox has to shave his head and face after a lice outbreak at his job. His hair stays gone and takes a long while to grow back, but he realizes that his goatee grows back just the way it was within seconds of being removed. He spends a strip doing nothing but shaving his goatee off repeatedly, watching it grow back, and giggling like an electrocuted heron.
* Lampshaded in ''AntiheroForHire''. Shadehawk actually chooses his hairspray on the requirement that if he's suddenly drenched, it'll dry off instantly. Commercially-available AppliedPhlebotinum at its finest.

* The current page picture is one of the few times where [[MediumAwareness Medium Awareness]] makes an appearance in [[LeastICouldDo Least I Could Do]].
* Justified in ''OrderOfTheStick'', when [[spoiler: Haley]] uses a magical hair growth treatment.

* Parodied in ''Houshin Engi''. Taikoubou and Suupuushan are shocked by an electric-based opponent, causing them to develop an afro and blonde curls, respectively. They stop in the middle of their fight to shampoo and blow-dry their hair back into its proper shape -- in ancient China.
