South Korean Idols must follow several strict rules non-existent in many other countries in the world that manages many aspects of their lives such as:
Image and Appearance: Idols are expected to maintain a certain image that aligns with their group's concept and the agency's branding. This includes aspects like hairstyle, fashion, and makeup. Hair colour and style changes are often subject to approval from the agency. There have been instances where idols were subjected to strict dieting regimens to maintain a certain physique.
Etiquette and Manners: Idols are expected to exhibit proper manners and etiquette both in public and private settings. This includes being respectful to staff and fellow idols, as well as maintaining a positive relationship with fans.
Social Media: Many agencies have guidelines for how idols should use social media. They might be advised to avoid controversial topics, refrain from sharing personal information, and maintain a positive online presence. Some agencies even manage the social media accounts of their idols.
Dating and Relationships: Many agencies have a "dating ban" policy, especially for newer idols. This is often implemented to maintain the illusion of availability for fans and to prevent potential controversies.
No Scandals: Idols are expected to avoid scandals and controversies that could negatively impact their image and the image of their group. This includes avoiding behaviours like smoking, drinking in public, and being involved in legal issues.
It's important to note that these guidelines can vary widely depending on the agency and the specific circumstances.
