Amid controversy surrounding her agency, the singer-teactor shares firm views on scalp care

Ok Joo-hyun, the singer and musical theatre performer, has weighed in with a candid stance on morning shampoo rituals.

On the 17th, she released a video on her YouTube channel, titled “Ok Joo-hyun’s Hair-Care Routine: Exploring Hair and Scalp Care Methods as Real-Deal Tips.” In the clip, she stated that “the biggest concern for musical actors is hair loss, and I underwent a hair transplant nine years ago.”

She added that she had grafts taken from the back of her head and implanted at the front, but the baby hairs disappeared, causing her significant stress. “Having money doesn’t guarantee a perfect transplant; if the hair roots don’t cooperate, even billions won’t help,” she said.

Regarding daily care, Ok Joo-hyun stressed that “not washing your hair at night and washing it only in the morning is the dirtiest habit in the world.” She argued that dust and pollutants accumulate on the scalp when you venture outdoors, so washing away the day’s buildup at night is essential. “Shampoo should be used twice: the first pass to remove dust, the second to nourish,” she explained, adding that now her baby hairs are returning and she can tie her hair freely once more.

Last month, Ok Joo-hyun faced public backlash over her agency’s alleged unregistered, illegal operations. Under the Act on the Development of Culture and Arts Industries, operators who run cultural and arts planning businesses without registration may face up to two years’ imprisonment or penalties of up to 20 million won. The Ministry of Culture, Sports and Tourism warned that once the grace period ends, unregistered businesses will be subject to investigations or administrative measures.

In response, Ok Joo-hyun issued a statement through her agency, TOI Entertainment: “We will ensure that all future procedures are handled with expert assistance to prevent any similar incidents, leaving no gaps. This incident will lead us to comply more rigorously with relevant regulations and procedures, and to act with greater sincerity and transparency moving forward.”
