That's really stupid. What so they want to be like every other garage band out there. I know tonnes of people in bands, and when they started out, that is the mistake so many of them make. They try to emulate their favorite bands. Only problem is, those bands already exist! No originality. I think they made a big mistake getting rid of you, try to find some other guys who have bands and see if they could use an awesome vocalist. Sounds like you've got some talent. If your ex band members can't appreciate that, then that's too bad for them.
You may just make it some day and they will be shaking their heads in shame. All over hair too, that is quite silly :P Hair isn't everything! Talent is important too! Besides, you don't want to look like every other band out there. Stand out, if you can't have your hair long, that's okay. Find a different way to stand out, be it with clothing, your vocals or other things. But sounds to me like it was probably a good idea for them to dump you, because they didn't appreciate your talent.
