On the 8th, Koo Hye-sun posted a picture on her personal account with the words "Hairroll Model Kurol."
In the picture, Gu Hye-sun is taking a selfie while lying in bed wearing a flat hair roll.
The porcelain-like smooth skin and doll-like features once again proved the dignity of the original best.
The hair roll released this time is a product researched and developed by Koo Hye-sun herself.
Earlier, he appeared on the channel 'KIPA' of the Korean Invention Promotion Association of Inventors to reveal the background of the product's development.
Koo Hye-sun said, "'Is there any hair roll that can be unfolded and attached after seeing celebrities wear hair rolls and appear in public?' That's what I thought"It was the beginning of the product development.
In fact, Koo Hye-sun obtained a patent with this product and established a venture company 'Studio Koo Hye-sun' to start her career as an entrepreneur.
Currently, Koo is studying for a master's degree in engineering at KAIST Graduate School of Science and Journalism.
