Whenever hairs are generated in Ox they are 'glued' to a part of the surface that is distributing them (if there is any). The main idea is to direct the flow of hair using shell cages. Hair shells is one of Ornatrix' approaches to this problem. The main goal of any hair plugin is to allow the user to intuitively describe the hair volume.

Shells force guides to conform to the new surfaces length-wise.
