On November 1, Goo Hyesun shared on her personal social media account, Preparing to launch KOOROLL,' and shared a photo of herself using the new product.
'KOOROLL' is a hair roll that Goo Hyesun, who is currently pursuing a Master's degree in Engineering at KAIST's Graduate School of Science Journalism, developed with Professor Lee Haeshin from KAIST's Chemistry Department.
Unlike traditional round hair rolls, this one is flat and rectangular, allowing users to bend and shape it to the size they want. It is also easy to carry because it is not bulky.
Goo Hyesun filed for the patent in July 2020 and officially registered it in December of the following year. Recently, she reportedly received confirmation as a preliminary venture company and is finalizing the launch roadmap with distributors.

[+230][-35] It’s not like a hair roller has some amazing function or something. If you want something fancy, you can just use an Airwrap, curl your hair, take it out, and hold it in a roll. It basically does the same thing. She’s just slapping a brand name on an simple hair roller to increase the profit margin.
[+215][-68] What’s wrong with these comments??
[+53][-27] She's unique, so unique.
