MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202617092157 A) filed by L'Oral on July 29, 2026, for Method And System For 3d Hair Virtual Try On Using Physics Simulation.
Inventors include Tang, Tsz To Jason; Yousaf, Hamza; Phung, Edmund; Lok, Yi Xin; Bokaris, Panagiotis-Alexandros; and Askenazi, Benjamin.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: The methods, systems, devices and techniques in accordance with embodiments herein aim to bring a novel approach to Hair Virtual Try-on by replacing the natural hair of the user with a 3D representation (e.g. mesh, point cloud, implicit function, etc.) that mimics how real hair behaves. In an embodiment a physics simulation of at least one force deforms the 3D hairstyle. In an embodiment, the 3D representation includes the details and texture information independently of the color to allow accurately calculation of the resulting color. In an embodiment, the hair color is applied in response to ambient light conditions as estimated. The 3D representation can be segmented by groups of hair strands (aka "mèches" of hair) which helps with achieving vertical recoloring such as highlights, contouring or balayage (a highlighting technique applied to real hair through painting hair color to create a graduated, more natural looking effect).
