Dabdoob, my recall there are only two caveates for working on the head.
1) Never take energy our from the top of the head.
2) Don't add energy to teeth (teeth problems) it increases the sensation of pain.
The rest is the standard detect, breakup, remove, add-back methodology. Do spend a little time to watch the video. It doesn't take long to learn the basics, or at least be aware of what they are. Those two points above are in the video.
You are perfection.
