Actress Goo Hye-sun is venturing into business with the launch of her patented hair roll.

On the afternoon of the 29th, Goo Hye-sun posted several photos on her social media, along with the caption, "The hair roll that is about to be launched soon. I'm in a heated meeting."

In the released photos, Goo Hye-sun appeared focused as she continued to hold meetings for the hair roll launch. She expressed her feelings with a smile, suggesting that the meetings were going well. Additionally, Goo Hye-sun seemed to have worn a lab coat while taking pictures with researchers and gave a slight preview of the completed hair roll.

Earlier, on a January broadcast of the MBC entertainment program "Radio Star," Goo Hye-sun granted news of the hair roll launch.

At that time, Goo Hye-sun explained, "I graduated from Sungkyunkwan University after 13 years. It's not just a simple graduation, as there's a system called '3 Goods', which requires filing for a patent or obtaining a certification. So, I filed for a patent. The product was made after seeing the hair roll," and added, "It's a hair roll that can be pulled out and used. I think it would be great if it could be served on airplanes."

Goo Hye-sun's legal divorce from actor Ahn Jae-hyun was finalized in July 2020 after a divorce mediation agreement, and she is currently enrolled at KAIST.
