Andy's Hair Test Book

You can find descriptions of Andy's main and more popular book at http://www.noamalgam.com and order it from Amazon if you like. But he has another book that is very important:

As far as I know, you have to order this direct from Andy. But it is a bargain, with a ton of outstanding information. A great resource for assessing hair tests and your levels of toxic and vital elements, and then solving the problems these hair tests uncover.
