The practice of Bollywood stars covering their faces while leaving or entering their houses is primarily driven by concerns related to privacy and security. Bollywood stars, like any other high-profile individuals, often deal with a significant level of public attention, including fans, paparazzi, and sometimes overenthusiastic admirers.
The decision to cover their faces is a measure taken to shield themselves from unwanted attention, intrusion into their personal lives, and to maintain some semblance of privacy. It helps prevent their photographs from being taken without consent and avoids potentially chaotic situations outside their homes.
In the past, Bollywood stars might not have faced the same level of media scrutiny and fan frenzy that they do today. However, even then, there was a certain level of reverence for celebrities, and they were often regarded with admiration and respect. While they might not have covered their faces back then, they likely had to deal with the challenges of maintaining boundaries between their public and private lives.
As the media landscape and celebrity culture have evolved, the need for privacy and security has become more pronounced. Thus, the practice of covering faces and maintaining distance from the public has become more common among Bollywood stars and other celebrities to manage the demands of fame.
