Riders have a tendency to change hairstyles as they move forward in their series, and as they move forward in life.
Only Riders with short haircuts I can think of at the moment are Riderman, ZX, Black/RX, Shin, ZO & J. The last 3 I think it's because of the era they were living in, those kind of haircuts were fashionable at the beginning of the 90's.
What I've seen so far during the 70's series, is that some characters start with a short, although not generic, haircut. Takeshi looked like an innocent college student, Hayato had it shorter, Kazuya's was extremely short, Shiro looked as innocent as Takeshi, Tachibana Tobei even had it long at the end of stronger.
To me it has always seemed they're too busy saving the world to go to a barbershop, it's only in some returns that you see them with shorter hair (V3 & Agito for example). Perhaps you could say they finally got a break, though of course the reason is the actor's preference.
Decade may have had short hair at the beginning of the series, though not by the second half, he only has it stylized, look at his DaiShocker haircut, that's long enough to me.
We need a BALD rider! :laugh:
I support this idea.
A guy like Hiroshi Fujioka SCREAMS "manliness". I could never imagine him without his long, thick hair.
Look at Hiroshi at the beginning of Kamen Rider. As I mentioned before, he could still look like an innocent young man.
And as for the short hair, Segata Sanshiro!
