I'd say for real hair your best bet would be something like Gatsby hair clay. I've heard that it's pretty much the end all to any wacky kinda hair you might want or the kind of typical 'Japanese anime boy' kinda look.
They've got a whole youtube channel
on how to use each different color, as each is suppose to have it's own unique consistency and staying power.
When people ask about how to get that 'jrock' kinda hair it's usually involving gatsby xD so I'd say maybe look at the video's they've got up on youtube and even check out videos or tutorials on WIG styling for your character, get some good hair clay and start messing around with a combination of both styling methods?
If you want to order gatsby stuff I know jbox has them here
the little disks are the hair clay ones.
