Right.  I was watching one of the older Ranma episodes, and 
noticed something.  When Ryoga has his flashback to China, he's not 
wearing his stripped bandanna... instead, he's got a regular headband on; 
also, Ranma-chan runs by with a pony-tail, not a pig-tail.
	So I was wondering... where did the bandanna come from?  And when 

Don't know...

did Ranma start wearing his hair in a pig-tail (the Dragon Hair thingy?  
Or didn't he have it that way at the very beginning?)

He got the pig-tail when he ate that stuff that made his hair grow really
fast when he's a guy ... used the dragon's whisker to stop it from growing,
and he tied off the pigtail with the whisker. This happened after he met
Shampoo, but before he got back to Japan.

Kun-chan...
