Question:

Can women with hair loss use Propecia and is it effective?

Answer:

Certain women that have genetic hair loss can try to use Propecia as a medication to slow down the progression of their genetic hair loss. 

In females that can document via either blood or saliva diagnostic testing that they have elevated levels of testosterone, more than the average female of their age would have, it can be possible to slow down the conversion of the testosterone to DHT by using Propecia. 

In my experience, only patients who are beyond their child bearing years with no consideration for having additional children would be considered a candidate for trying Propecia to see if it could slow down the genetic hair loss.
