Flying 12 hours to Los Angeles — only to stay less than 12 hours — sounds brutal enough. Doing it repeatedly while battling physical pain makes it worse. But what caught fans’ attention was not the grueling schedule — it was BLACKPINK’s Rosé quietly upgrading her stylist to business class for a one-day trip. Rosé has become the subject of online praise after her longtime hairstylist shared a behind-the-scenes story about the singer’s generosity. The anecdote surfaced in a recent video on the YouTube channel Workers’s High, titled “BP Rosé’s 7-Year Blonde Secret & LA Day Trips | ChaCha.” In the video, celebrity hair artist Cha Jong-hyun — known professionally as ChaCha — spoke about working with global K-pop stars including BLACKPINK, Sunmi and i-dle. He said Rosé has maintained her signature platinum blonde hair since debut, even at the cost of scalp damage, requiring root touch-ups every two weeks. That two-week schedule continues even when Rosé is overseas. “When it has been two weeks since bleaching and Rosé is in the U.S. or Paris, I go,” Cha said.
