The cloth room is still popular, and I use it a lot myself, but I've never seen a good looking dynamic hair yet.. :(

I tried doing them myself and had very little success.. All the dynamic hair products I've seen, free or elsewise look completely unnatural..

Maybe most of us haven't figured out how to use it well.. 

My trial was to make (or find) a good looking, long, dark, wavy female hair.. Haven't seen anything that even comes close to looking half decent.. 

I agree with Trekkiegrrl on animations..   I've have not had much success with conforming, transmapped hair in animated scene. (Same problem as with conforming clothing thath as a lot of fabric), it just looks stiff and unnatural when the character moves...

There's plenty of good looking dynamic clothing, and more is made every day now..

If anyone succeeds in figuring out how to make nice long wavey female hair that's dynamic and looks realistic, I'd be first in line to pay for it!
