Until recently, scientifically-validated hair loss treatments consisted entirely of compositions formulated to block a key precursor enzyme (5 alpha-reductase).  This enzyme precipitates the conversion of testosterone (T) to dihydrotestosterone (DHT).  DHT has been compellingly and repeatedly demonstrated to represent an important negative factor in the onset and progression of pattern hair loss, also known as androgenetic alopecia (AGA).

Androgenetic Alopecia (AGA) is by far the most widespread form of hair loss affecting more than 95% of those who experience loss of hair. It is axiomatic that the younger a person is when they begin losing hair the more severe the degree of loss will be. Until recently, few safe and efficacious options of any kind were available. 

In the past several years a number of options have been tested and made available. Two choices will be discussed in this response. The first is pharmacotherapy (Rx). The second is non-drug, botanically-based.
