heyas; mine did that all the time too, until i got straightened out. this is how you do it: 1: import your cloth-hair prop. don't parent it to anything, or you'll be messed up. 2: clothify it as normal. make sure you create a constrained group at the roots, where you want it stuck on the scalp. 3: NOW parent the cloth-hair to the head. then the vertices will stick to it. remember: constrain first, parent after.
