It is not adding or subtracting polys, The issue is how Daz Studio handles shells though, When you originally add a shell it covers all of the underlying figure and any grafts, when you add a second graft Daz Studio adds the new material zones from the grafts to the shell, the added material zones from other grafts is why shells will often give you the white shell effect, where a shell added by default is loaded with all the unnecessary material zones turned off, when adding additional grafts, the shell script doesn't have texture information for surface X or rules that surface X needs turned off so you get white material added to the new surfaces, this also occurs when a new shell is added. The problem with the Strand Based Hair is the added material zones in the GP shell makes Garibaldi think that the shell it has been attached to is not the correct object, so it breaks the parent child connection between the Strand Based Hair, and the shell.
So other than suggesting that the default GP shell be used, and no other grafts and shells used in scenes using the Strand Based Hair. The only fix I can think of would be building the hair attachment on the GP graft, rather than the shell and hope that the shell interacting with the hair in close proximity doesn't cause artifacts to appear.
Really the best solution would be Daz reworking how shells are implemented in Daz Studio, but after so long, it is safe to figure that the way shells interact with each other and multiple grafts, as far as Daz is concerned, it is working as intended.
