What's happened to my hair? Audric:
You've gotten a little streak from the shock of the Dark Gift. Not unusual. The shock's greater for some than others... why, I used to be a brunette! Imagine! And as for Ginevra, she used to be a man
Let's say you're a typical protagonist, and you've stumbled upon a MacGuffin
or had some kind of incredible, scarring experience. It tends to change you— and it especially tends to change your hair. Skunk Stripes
, Multicolored Hair
and more are common mementos left on your once lovely locks.
Compare Power Dyes Your Hair
, which is strictly supernatural, often coming and going with the phenomenon causing it; and Disease Bleach
, which occurs as a result of more mundane causes and isn't spontaneous. See also Shapeshifter Mode Lock
. Contrast Kaleidoscope Hair
, when the change isn't permanent and can happen for other reasons.
As a trauma trope, expect spoilers.

Anime & Manga
- Probably the most famous example in anime, in Fist of the North Star, Rei's hair turns white after his life is extended by Toki's use of his Shinreidai pressure point.
- The first time Guts uses the Berserker's Armor in Berserk, he gets a white streak in his hair.
- At one point in the manga, Tetsuo's hair turns completely grey as the result of a major psychic revelation. Later, after he shortly turns into a Blob Monster then reconstitutes himself, his body has lost all pigmentation.
- The three psychic children that survived the original catastrophe besides Akira (Kyouko, Takashi and Masaru), also all have white hair (along with albino skin and premature aging), but we don't know if this was gradual or not.
- In Mermaid Saga, Towa Kannagi's hair turns completely white overnight when she drinks mermaid's blood.
- In the manga version of Chrono Crusade, Aion's hair turned completely white (on top of his skin becoming darker, for whatever reason) when he saw forbidden knowledge during his coming-of-age ceremony, including the fact that the demon's Hive Queen was originally a human woman pregnant with twins — him and Chrono. It's implied his hair and skin color was identical to Chrono's before the change.
- Half the hair on Jio's head from Six Six Six Satan is white, to go along with his heterochromatic eyes. Being possessed by Satan does wonders for his personal appearance.
- Read or Die, the TV series: In the final episode, Joker's hair turns entirely white after being put in direct contact with the mind of Mr. Gentleman. He also goes more or less catatonic.
- In the Gungrave anime, Brandon's black hair turns grey after he's reborn as "Beyond the Grave".

- In Soul Eater, Death the Kidd's three horizontal hair stripes, which normally only cover half of his head, begin to stretch around to the other side of his head and connect one at a time when he receives a major power up. In the manga, this happens because he had been carrying a powerful MacGuffin called BREW which unlocks his true potential. In the anime, it just happens spontaneously. In the manga this is only temporary. However, when he reaches his full potential on his own in the final battle, the hair stripes connect permanently and he becomes a true shinigami in place of his father.
- Argento Soma sees protagonist Takuto developing one heck of an epic streak after his girlfriend and her mentor are flattened by the wreckage of a laboratory demolished by an... escaping alien named Frank. No, really.

- Late in the manga of Trigun, it's revealed that Plants are born with blond hair, which turns black as their power is used up, and when it changes completely they will die. This is unfortunate news, as Vash at this point has mostly black hair.
- Readers can actually watch Vash's hair turn from almost completely blond to nearly black throughout the story; the changes appear incrementally, and after each time he uses his Angel Arm.

- No6's main character started out looking like a regular dark-haired Japanese guy.

- In the Belgian series Papyrus, the title hero had his once raven-black hair turn white after being frightened to death by a venomous snake crawling over him for hours. It's a plot point later, as an evil demon sees the white-haired Egyptian kid and is shocked to death as well, which saves Papyrus's life.
- Astro City's Samaritan has his hair turn blue after the Time Travel incident that gives him his powers. He can change it to white at will, but apparently not back to its original black. His archenemy Infidel's hair also changed color as a result of the same incident, going from black to green, though when not using his powers it's blond.
- In The Corinthian: Death In Venice, Amedeo's hair turns abruptly white when his body is possessed by the Corinthian. His already mentally-disturbed lover, Coco (or Pestilence, or Columbina), alludes to this trope, saying she's willing to bet it didn't happen out of fear...

- In X-Men, Rogue got her trademark Skunk Stripe after her powers first manifested. She was having her First Kiss, and accidentally sent the boy into a coma. This event triggers a lot of guilt on Rogue's part, and throughly establishes to her the danger of her ability. Afterwards, she starts isolating herself from others.
- In Preacher Herr Starr's hair fell out when he was five years old the night after a group of boys scratched his right eye out.
- Nathan Never. After seeing her wife horribly slaughtered by a man he arrested time before, most of his hairs (all but the sides) turn white. Instantly, to the horror of a couple cops present.

- Gentaro has black hair as shown in Horseshoes and Hand Grenades. In SplitxEnd, it's stated that he originally had white hair because he's a descendant of Asclepius. He gained the black hair after a traumatic experience in his life—his parents' death. Tears to Shed also hints that the power also has to do with Ophiuchus saving him from death.

However, after she thaws out following her Heroic Sacrifice, her hair no longer has the streak.
Films — Live-Action
- In Young Frankenstein, Elizabeth's hair gets a white streak after she's been abducted by the monster. This is mostly so she can have the Bride of Frankenstein hairdo later, because it's funnier that way. Of course, then there's the Bride herself...

- Same goes for main character Sam Peebles in "The Library Policeman" (Four Past Midnight).
- In David Eddings' Belgariad and Mallorean series, this is the reason for Polgara's white lock. She got it when her father, the sorcerer Belgarath, first laid his hand upon her after she was born. It resists cutting and dyeing, which has led to some interesting dilemmas when they've been trying to hide from their enemies. This trope shows up in the entire Rivan royal line, too, and (possibly?) all the disciples of Aldur. Polgara's hair is just the most striking example.
- With most disciples, it appears as a sort of birthmark.
- Additionally, Belgarath's hair is entirely white (as befits his age). In the Book of Alorn, this is put down to frost settling in his hair during the trek across the frozen land bridge between Aloria and Mallorea. But in Belgarath the Sorcerer, he claims that it had gone white before then, and blames stress from dealing with the Alorns. However, the early narrative points to a more prosaic reasion: he'd simply been around for a while and lost track of time.

- Fitz from the Realm of the Elderlings series had a literal scarring experience that turned a streak of his hair white — someone bashed him over the head with an axe. He decided to go by the name of Tom Badgerlock in the second trilogy for this very reason. He got better later in the series, and had to quickly figure out why he now no longer had a white lock in his hair.
- Erast Fandorin's temples become completely gray (in sharp contrast to the rest of his hair, which remains black until very old age) after witnessing his wife blown to pieces by an assassin's bomb in the end of the first novel. In a much later book, the villain used this characteristic trait (and a few others) to successfully impersonate Fandorin.

- As Torchwood revealed courtesy of Martha Jones in the episode "Reset", enough exposure to time radiation will forever alter you down to the genetic level, which had the added effect of granting a limited immunity/resistance to being caught up in events that change the timestream in unnatural ways.
- Doctor Who elaborates on this by saying that as a time traveller, you perceive time differently: one benefit is that you will still remember anything that was lost by time being rewritten or even unwritten (but you have to try really hard). And please try very hard not to conceive a child while within the time vortex itself (in the safety of a Tardis), or it might just grow up to be a Time Lord.
- Ordinary Galifreyans became true Time Lords through centuries of exposure to time radiation, making them nearly ageless and damn close to immortal, and able to perceive all possible pasts and futures.
- The early Charmed episode "From Fear to Eternity" has Prue's hair turning slightly white due to nearly drowning because the sisters are being targeted by Barbas for the first time; all the other witches targeted by him die of fear, with completely white hair.

- Deadly Premonition. Zach's hair turned from brown to white upon witnessing the dead of both of his parents and being attacked by Kaysen.

- In Warcraft 3 Arthas' hair goes white after his experiences in Northrend, though it's not entirely clear if it was the result of the magical influence of Frostmourne or simply stress, obsession and trauma combined with frigid weather.
- In Mists of Pandaria, Arthas's ex-girlfriend Jaina Proudmoore gets white hair of her own (with a single blond streak) after her Despair Event Horizon.

The shaman Kili's hair turned white when she was haunted as a child, and when Kili and her boyfriend Greg became werewolves later, a side-effect was their hair growing really long. There's also been one case of a woman trapped in slow motion having her hair grow several inches when she's accelerated back to normal speed.

- The Life and Times of Juniper Lee: Juniper Lee developed a fuchsia Skunk Stripe upon becoming the Te Xuan Ze. Her grandmother's streak turned gray upon the transfer of power. The streak may actually be white (she just dyes it fuchsia), though past Te Xuan Zes seen in flashback have the same fuchsia streak. (Most notably a male one from what's probably the middle ages, before they were likely to have that kind of hair dye.)
- In the episode where June is shown getting her powers it's plain white, so she probably dyes it to avoid attracting too much attention. The fuchsia steak also fits in rather well with her status as a member of her brothers' rock band.
- In Transformers Animated, it's been revealed that this is how Isaac Sumdac got the grey/white streak in his otherwise black hair. He found a protoform, and when he touched it, it did... something to him while scanning his DNA, resulting in said hair.

- According to the "Cutie Mark Chronicles" episode of My Little Pony: Friendship Is Magic, Pinkie Pie's curly mane and tail used to be straight, until she was hit by the force of Rainbow Dash's first sonic rainboom, which also made her want to spend her life smiling and having fun. This is proven in a following episode, "Party of One", where her hair immediately loses its curl when she thinks her friends no longer like her and all the joy drains out of her life.
- Referenced in the next episode, "Best Night Ever", where she tries to straighten her hair. It works...for about three seconds, when her excitement about the Grand Galloping Gala causes her hair to become curly again.

- In the Legion Of Superheroes In his normal form Timber Wolf's eyes, fur, claws, fangs and pointy ears were a result of his father tampering with his DNA too much. Before he was experimented on he was a normal looking human boy. After being shocked by the Lightning Beasts, Garth and his brother, Mekt ended up with electric blue eyes instead of brown as well as Garth's scar on his face and Mekt's dark hair turning white, after the events of Dark Victory Brainy became human (except he still had green skin and white circles on his forehead in the shape of the Brainiac symbol) when he was an android for the previous episodes.
- There's an autoimmune condition called alopecia areata, which causes hair to fall out. If your hair has started to go gray, the condition will preferentially make the darker hairs fall out. Further, autoimmune conditions can be brought on by sudden stress. Ergo, a shock can trigger this condition, your dark hair falls out, and what's left is much grayer... This is probably the origin of this whole trope.
