Clamp Rotation of an object depending of the Rotation of an other one

Hi, I'm trying to limit the pan and tilt of the head of a character without limiting the camera. I'd like the player to be able to move the camera as much as he wants but I don't want the Head of the character to follow the rotation if it goes over a certain angle.

This is my code so far, it's not working great:

 void Update()
     {
         float angleX = 0f;
         float angleY = 0f;
 
         if (!isLocalPlayer)
         {
             return;
         }
         angleX = Mathf.Abs(head.CameraTransform.localRotation.x);
         angleY = Mathf.Abs(head.CameraTransform.localRotation.y);
         if (angleX < 0.3f)
             tHead.localEulerAngles = new Vector3(head.CameraTransform.eulerAngles.x, tHead.localEulerAngles.y, tHead.localEulerAngles.z);
         if (angleY < 0.7f)
             tHead.localEulerAngles = new Vector3(tHead.localEulerAngles.x, head.CameraTransform.eulerAngles.y, tHead.localEulerAngles.z);
     }

Any help is welcome.
