Cookbook author and television presenter Rachel Khoo says she does not wear perfume because of a personal experience that has left her “kind of traumatised.” According to multiple outlets, Khoo links her decision to a reaction she associates with scent, describing how the matter has influenced her preferences for years. The reports also frame her approach as part of a wider pattern: Khoo is known for cultivating a distinctive on-screen and public style, including a limited set of signature choices that her audience recognizes. Several articles note that fans can be particularly sensitive to changes in her appearance or routine, and that this expectation has played a role in how she presents herself in public. While the stories focus on the same explanation for why she avoids perfume, they differ only in framing details and context, not on the core point. Overall, the articles present Khoo’s perfume choice as a result of a past event and a continuing personal comfort boundary, alongside a broader consideration of consistency in her public image.
