From my experiance, you can use anything in the styling controls or the cynamic controls without wiping out the style. However drastically changing some of these will affect how the style looks just like someone with fine kinky hair will look different on the same style as someone with thick straight hair.

Collisions seem to be more of a scrunch up the end of the line so it doesn't continue into the object it like a straw wrapper still on the straw. If the push it down on the table it crumples. My attempts to move hair with a prop have failed miserably.
