Dutasteride vs finasteride, what is the scoop?

Doc, can you write a post detailing the effectiveness of dutasteride vs finasteride for hairline and general thinning if you ever get the chance?

These two drugs work in a similar manner. These drugs are competitive inhibitors to the enzyme 5 alpha reductase, critical to the functioning of DHT. Dutasteride is reported to be 85% effective while Finasteride is reported to be 70% as effective. That does not mean that dutasteride is a better drug, with know side effects that may be worse than finasteride like sterility. Finasteride is approved by the FDA for hair loss while finasteride is not.
