The only headache I got was when I started using Coconut oil because it is so strong I believe I had toxic overload.

Start with sunflower oil, its not as strong.

You wont know until you try it but I doubt this kind of oil would cause the same kind of headache as oil on your face, but you will never know until you try it.

good luck

I recommend OPg for just one or two minutes at first. I have experienced awesome results doing this. I really believe the OPg will correct whatever is causing the headaches.
example; LESS than one minute of OPg helped me expell a dental abscess.

What kinds of oils have you had in your mouth?

If we were talking veggie or canola oils compared to sunflower and coconut - it's a whole different ballpark!
