yes Simon JM said,,
we can just remove the morphs value, which are auto generated to hair.
and I recomend if you want to save the scene, and not changed shape of hair
by generated morph anymore,,
after reset each generated morphs of the hair value to zero,
then change the these generated morph type “auto-generated” to “modifier/shape”
by parameter controller gear.
edited (soryy,, I missed about auto-follow option, it seems work as saved scene too)
or check off the option “auto-follow” about each morphs to make genesis shape.
the status can save as scene. (it seems more easy, to change generated morph type)
then save it as scene. it can work about the scene.
