Problems when rigging; only some of the object moves with rig even when automatically weighted? I have this character I am trying to rig. I created the rig, and did not apply automatic weight yet. I have his hair in a separate object, so I joined the character and his hair with Ctrl+J. I then added automatic weight to the armature, but some of his hair does not move with him. 

How can I fix this? Ctrl+P Keep Offset gives a similar issue.

Here is the blender file:

Select the hair, then a head bone and press Ctrl+P-->Set Parent to-->Bone.
