Ku HyeSun Announces KOOROLL Launch: A Patented Hair Roller

Actress and inventor Ku HyeSun has officially announced the upcoming KOOROLL launch on November 01, 2025. The new venture introduces a patented hair roller she developed while studying at the prestigious Korea Advanced Institute of Science and Technology (KAIST). Ku HyeSun shared the news on her personal social media, signaling her official entry into the world of entrepreneurship with a unique beauty product.

The Journey From Idea to a Patented Product

The development of KOOROLL has been a multi-year process, beginning long before the official announcement. Ku HyeSun first applied for a patent for her innovative hair roller design back in July 2020. After a thorough review process, the patent was officially registered in December 2021, cementing her status as an inventor and securing the intellectual property for her unique creation. This significant milestone laid the groundwork for the development of the Ku HyeSun product.

What Makes the KOOROLL Hair Roll Patent Unique?

Unlike traditional cylindrical hair rollers, KOOROLL features a distinctive flat, rectangular shape. This patented design is not only innovative but also highly functional. The product is designed to be customizable in size, allowing users to adapt it to their specific hair styling needs. Furthermore, its unique form factor makes it exceptionally portable, offering a convenient solution for on-the-go touch-ups. The official hair roll patent protects these key features that set KOOROLL apart from other products on the market.

A Fusion of Art and Science: The KAIST Collaboration

Ku HyeSun’s academic pursuits played a crucial role in bringing KOOROLL to life. While pursuing a Master of Engineering at the KAIST Graduate School of Science Journalism, she engaged in a productive KAIST collaboration. She co-developed the product with Lee Haeshin, a Distinguished Professor at the KAIST Department of Chemistry. This partnership combined Ku HyeSun’s creative vision with top-tier scientific expertise, resulting in a refined and market-ready product. This kind of cross-disciplinary innovation raises interesting questions about the future, including how technology might shape other industries.

Preparing for the KOOROLL Launch

With the product fully developed, Ku HyeSun has been actively preparing for its market debut. She recently received a preliminary venture company certificate, a key step in establishing her new business. Currently, she is in discussions with a distributor to finalize a comprehensive launch roadmap. The announcement on November 01, 2025, which included a photo of the product in use, marks the beginning of the official countdown to the highly anticipated KOOROLL launch. Fans and consumers alike are eager to see the actress’s innovative vision come to fruition.
