Characters from Tokyo Ghoul whose hair changed color through their transformation
Kishou Arima and Yusa Arima
Are half-humans capable of premature aging, which causes their hair to turn gray more due to their biology.
Unlike other characters, he is one of the few humans who appears to have albinism due to the presence of red eyes, a color only albinos possess. It is unknown whether Juuzou's hair changed due to Big Madam's torture. Although there was an original concept that Juuzou's hair was orange.
Currently, his hair is dyed black as a form of mourning following Shinohara's vegetative state.
It is a known case that Kaneki's hair color is due to Antoinette Syndrome caused by stress. However, this was changed because the suppression of RC cells leads to increased melanin production. This also occurs in humans because they have RC cells in their bodies.
Kaneki's hair changed every time he suffered multiple injuries or through symbolism and decline, reflecting the personality he would have now.
His transformation into a dragon is complex. It's unknown whether Kaneki became a dragon, remains an artificial one-eyed ghoul, or both due to contact and a relationship with the dragon, but his hair grew a little. Currently, his hair is still white, and he appears to be physically restored thanks to the dragon.
Like Kaneki, Takizawa's hair turned from brown to white when he was with Kanou and his RC cells were suppressed during experimentation. He also became an artificial one-eyed ghoul.
He currently lives as a ghoul with no return to his former normal life.
Supposedly, his lifespan is decreasing, possibly due to s tress.
Tooru's case is complex because she was human before. At the beginning of :re, Tooru is a Quinx (still human) but the result of a failed sur gery led to ghoul-like consequences. However, this gradually changed as Tooru fell deeper into despair and the stress Torso caused her (which turned her hair white) led to a ghoul transformation shortly after (likely triggering her). Similar to Urie's transformation, but this time it's more artificial, like Kaneki's.
In the end, Tooru's hair appears to return to normal thanks to Sui's sketches. Her biological condition is unknown.
Rize had purple hair and was a ghoul wanted by the Washuu.
Her hair turned white due to the suppression of her RC during her dragon transformation. She was captu red by Arima and later by Furuta, who used her as a womb for the Oggai.
Currently, Rize has become part of the Dragon itself, so she doesn't seem to react.
Previously a ghoul with light green hair due to the Jail game.
Because he joined Aogiri, as an adult, his hair grew long and dark, most likely due to the filth of the place. He is slender with a muscular build.
He is currently in a kakuja state; his limbs have become thin, along with four other limbs, and his long hair still covers his face.
They were human children aged 11-13 who became a new ghoul race thanks to Rize's kagune and Qs's research.
Their hair turned white after breaking their two halves and suppressing their RC cells.
