peroxide
Peroxide appears in The Outsiders as a crucial tool of disguise and a symbol of the loss of identity. When Johnny Cade and Ponyboy Curtis flee to the abandoned church on Jay Mountain after Johnny kills Bob Sheldon, they realize they must alter their appearances to avoid detection. Johnny purchases a bottle of peroxide along with other supplies, and it becomes the agent of a profound physical and emotional change for Ponyboy.
Purchase and Purpose
Johnny brings peroxide back to the church as part of a week's supply of food and other items. He explains to Ponyboy that they need to cut their hair and bleach it because their descriptions will be in the newspaper. Ponyboy protests vehemently, calling his hair his "pride" and "the one thing we were proud of." Johnny insists, arguing that the police and the judge will cut their hair anyway if they are caught. The peroxide is thus presented not as a cosmetic choice but as a necessity for survival, a forced alteration of a core part of their greaser identity.
The Bleaching Process
After Johnny cuts Ponyboy's hair with his switchblade, he applies the peroxide. Ponyboy sits in the sun for fifteen minutes to let the bleach dry. When he finally looks in an old cracked mirror, he is horrified. His hair is even lighter than Sodapop's, and combed to the side in an unfamiliar way. He feels it makes him look younger, more scared, and like a "blasted pansy." The peroxide has not only changed his hair color but has stripped him of the visual marker that defined him as a greaser and gave him a sense of belonging and toughness. The transformation is so complete that he feels he is in a "Halloween costume we can't get out of."
Symbolic Significance
Peroxide, along with the haircut, represents the erasure of the boys' former selves. Their long, greased hair was their "trademark" and a source of pride in a world where they had little else. By using peroxide, Johnny and Ponyboy are forced to shed this emblem of their gang identity. The chemical process is irreversible in the short term, mirroring the irreversible act of killing that has set them on this path. Later, when they decide to turn themselves in, Johnny laments that they "ruined our hair for nothing." The peroxide's work, which seemed so necessary, becomes a pointless sacrifice, a permanent reminder of their time in hiding and the loss of their innocence. The act of bleaching also foreshadows the deeper, more permanent changes the boys will undergo, as Ponyboy's hair eventually grows back, but the psychological scars from their experiences do not.
Contrast with Greaser Identity
The use of peroxide stands in stark contrast to the greaser culture of long, greased hair. Throughout the novel, hair is a central symbol of greaser identity and pride. Ponyboy notes that their hair "labeled us greasers" and was something they could be proud of when they had no money for nice clothes or cars. Before the rumble, the greasers put on extra hair oil to "show that we were greasers" and be proud of it. Peroxide, by lightening and altering the hair, directly attacks this symbol. It is a tool of the dominant society, used to make the boys conform to a more acceptable appearance, just as the judge would force a haircut. The peroxide thus becomes a material agent of the social pressure to erase their greaser identity, a pressure they must resist even as they use it to survive.
