Platinum blonde hair has become a "brand" associated with Rosé's (Blackpink) image for many years. Recently, in an interview, hair stylist ChaCha (Cha Jong Hyun) - the person behind the appearance of Blackpink, Sunmi and (G)I-DLE - revealed a little-known story about the female idol's journey to maintain this characteristic hair color.
According to ChaCha's sharing, Rosé has maintained her blonde hair for about 7 years and regularly bleached and trimmed her hair roots every two weeks. "I once told Rosé that the frequency is quite high, so it can be stretched to protect her hair and scalp. But she replied that what is more important is her public image," he recounted.

Not only regular in terms of time, this process also requires continuous movement. Every time Rosé has a hair extension schedule while abroad, ChaCha will immediately fly to where she is, from Paris to the US, to ensure that her hair color is always perfect. There are trips that last less than 12 hours in Los Angeles or San Francisco: fly 12 hours, do hair for 3-4 hours and then go to the airport to return to Korea on the same day.
This information quickly attracted the attention of netizens. Many people expressed surprise when Rosé could maintain bleaching her hair roots twice a week for 7 consecutive years. Many opinions believe that to keep such long-lasting blonde hair requires healthy scalp, careful care and a significant cost.
Besides, there are also comments worried about the risk of damage when frequently exposed to chemicals, even asking why the female singer does not try to change her hair color or use wigs to reduce the direct impact on the scalp. However, most fans admit that blonde hair has become an irreplaceable mark in Rosé's image on stage and in everyday life.
In another development, ChaCha also revealed that member Jennie once joked that she would "call the police" if her hair was damaged to the point of having to be cut because of dyeing - showing that idols are very aware of protecting their hair amidst a tight schedule.
Although there is still much debate, this behind-the-scenes story once again shows the pressure to maintain the image of K-pop stars, where every small detail - including hair color - is maintained with almost absolute professionalism.
