In the realm of virtual hair try-ons, existing hair transplant technologies often face challenges with diverse and complex hairstyles, leaving many users disappointed. Recently, a new study has proposed an innovative solution called Stable-Hair. This technology utilizes diffusion models to accurately transfer a variety of real-world hairstyles onto user-provided faces, offering a fresh hair-trying experience.

The Stable-Hair framework employs a two-stage processing flow to achieve optimal results with minimal modifications. The first stage involves training a "baldness converter" using stable diffusion technology to remove hair from the user's facial image, generating a "bald image." This step, although sounding somewhat peculiar, is essential for subsequent hair transfer.
In the second stage, Stable-Hair completes the hair transfer through three unique modules. The first is the "hairstyle extractor," which encodes reference images with the target hairstyle. Next, the research team uses the "latent identity network" to ensure consistency in identity and background between the source image and the transfer result. Finally, through the "hair cross-attention layer," the target hairstyle is accurately transferred onto the newly generated bald image, achieving highly detailed and high-fidelity results.
After extensive experiments, the results show that Stable-Hair outperforms existing hair transfer methods, reaching a state-of-the-art level. The introduction of this technology will significantly enhance the user experience in virtual hair try-ons, allowing everyone to easily try out different hairstyles and enjoy the fun of changing looks.
