actually, i never assigned any collision object. It just happened that way.
To be honest, i was trying to make a funny-looking character and was messing around with funny hairstyles, and stumbled on this stuff. Then i thought "hey, sum1 on CD wanted to know how to do this" and i posted the vid.
So my guess is that you probably are making it harder than it needs to be. That happens alot, esp. in max, where there is a lot of stuff going on. try just redoing the hair and making sure you don't change anything that doesn't need to be.

BTW, im just doing grass, too. the head is just when im messin at home.
