Olivia Rodrigo Sparks Debate After Using Underarm Sweat to Style Hair

Pop star Olivia Rodrigo sparked a fierce online debate after a video from her Washington, D.C. concert went viral, showing her using her own underarm sweat to slick her hair back into a ponytail mid-performance.

The viral moment captured during a live show divided fans into two distinct camps, with some calling the move gross while others praised her edgy authenticity.

While performing her track Serena Joy amid high stage temperatures, Rodrigo was caught wiping her underarm and running her hand through her hair. The footage quickly drew a flurry of reactions on social media. Some users criticized the gesture as unhygienic and a forced attempt to look rebellious, with one writing that it was simply disgusting. Conversely, supporters rushed to her defense, calling it one of the coolest things she has ever done.

Medical professionals, however, advise against adopting the makeshift styling hack. Dermatologists noted that while sweat itself is not inherently harmful, leaving it trapped with salt, oils, and heat can lead to scalp irritation and itching.
