Exclusion of Hair from a drop action

Second Technician Rimmer

In the case of a long haircut, especially of the dforce kind, if you lay a G8F on her back and choose to have her drop to the floor with CTRL-D, what will be considered as the contact point on the character might not be her body but her hair. Is there a way to exclude the hair from the equation so that her back, butt and legs touch the floor ?
