DHT and Progesterone?

I know that DHT is a derivative of testosterone. I read on some hair site that DHT is also a derivative of progesterone. Is this true or not?

I don’t know if DHT is a derivative of progesterone. I get conflicting information from various sources. According to HairSite, progesterone inhibits the enzyme 5-alpha reductase, thereby reducing the DHT that is normally made from testosterone.

In this reference, the derivatives of the various steroids are discussed which may answer your question better.
