So.. Jrock mullet wigs anyone? -img heavyish-

Well there are Luts wigs that are close too this, you probably just have to cut and style it:





and here's just random old pics of Larue...people have said that he had jrock/mullet hair XDDD;

 

Bumb for this. I want to see more.

 

Crobidoll furwigs are great for the Mullet look - they are so full, even the simple 'short' versions can be styled like that:


as so-fiii's Kris demonstrates^^

But there are several more wigs nowadays that could work for the purpose:

http://vier4d.com/shop/index.html?tch=detail&mcate=A205&goods=425 - wavy^^

I think furwigs with fiber extensions look very much like the ones the OP linked - though in many cases the extensions could be trimmed shorter/raggier^^
