The only time I've seen anything like that, is when I've made the supporting prop  dynamic also (I've been working on furred clothing pieces).  

Occassionally, when I've got too much going on the program looses track of what goes where.

 But never when the supporting item is static, as your hair would currently appear to be in the screenshot.
