I'm very sorry to hear about what is happening to your wife.

Elevated DHT causes hair loss and mercury causes elevated DHT. This also happened to me. http://herballure.com/v/mcs

Removing amalgams is well accepted as the best way to stop mercury exposure from amalgams (obviously), so as long as they are removed by a dentists who does it safely, many recover from mercury symptoms.

Doctors generally know little about mercury diagnosing. Urine tests are well-known to be useless, but most doctors still don't know this.

Here are a list of dentists who have been trained in safe mercury removal: http://iaomt.org/patients/search/index.php

Also, please be aware that we are also being bombarded with heavy metals from chemtrails overhead. For in-depth information about this, please see my personal story: http://globalskywatch.com/v/mcs
