I should add this hair suffers a lot from the alpha bug in the SL client. It makes prims that contain transparency render in the wrong order, so you might see prims on the back showing as if they were in front and such. Surely you already seen this. Ugly bug, ugly ugly! Btw if you look south, there's no prob (not kidding).
If you want it to be fixed you can vote for it in the bug tracker here: http://jira.secondlife.com/browse/VWR-504
