I appreciate your reply. I don't think I agree with anything at all on quackwatch.com.
Dr Larry Wilson is the MD I'm seeing about this hair test. He's an older man, the same age as me (56) and is very experienced with holistic health. I've had many hair tests in the last 25 years. Dr Wilson is IMHO one of the best with this. http://www.drlwilson.com/
It may not be a great therapy for me right now but it's helped in the past and seems to help many people.
