Abstract: Hairstyle has a very important impact on one’s appearance and temperament, resulting in an
increasing number of related consumption. Consumers’ hairstyle cannot recover after changing, so a
preview of hairstyle and hair color is necessary. There are obvious defects in the existing solutions, such
as hairstyle pictures and hairstyle try-on applications based on two-dimensional images processing
technology, which provide unreal effect. In this paper, we propose a 3D virtual hairstyle try-on system
for mobile platform. Combining with virtual reality technology and the reconstruction algorithm of 3D
head model based on single photo, this system can provide much more real effect. Users can have
multi-angle observation and change hair color or accessories. In addition, the system is built on the
mobile platform and optimized through reasonable framework design and resource management to
improve user experience and practicality and meet the needs of mobile users.

Key words: virtual hairstyle try-on, mobile application, 3D reconstruction, face algorithm
