Aderans, the Japanese equivalent of Hair Club for Men has a neat online service called HairTry that allows you to upload your picture and try on various hairstyles without having to leave your home.
It processes the uploaded 2D photo and converts it into a 3D image, adding facial gestures and eyeballs that follow your mouse as you navigate the site. In addition to hair, the site offers a small selection of eyeglasses.
The site is entirely in Japanese and runs in Adobe Flash. Below is a quick tutorial on how to upload your head, pick hairstyles, and export it into an amazing image file you can use on your social network of choice. Have fun.
