onurcangoc Sorry to wait so long for an answer! I was on vacation and hadn't seen your post yet.
I answered your question earlier in another thread, and you may still not understand how the bone hierarchy works. Our example skeleton, Spineboy, also has a separate face, eye and mouth, but they are all children of the head bone, so when the head bone moves, they all move together.
So in your case, if you make the eyes, eyebrows, and bangs the children of the bone to move the head, you can make them move together when you move the head bone.
