I took finasteride 1mg for two years, and it did not stop my hair loss. Five weeks ago, I switched to dutasteride .5mg, and I am still seeing the same level of hair loss. What are some of the possible factors resulting in my continued hair loss? Might it have something to do with the DHT still residing in my scalp?
Also, how much of a decrease in DHT is generally required in the blood and/or scalp in order to stop hair loss?

Neither dutasteride or finasteride are guaranteed to stop the hair loss. There is a race between your genetics and your attempt to stop the loss and from what you are saying, your genes are winning. If you were to become a Norwood Class 5 balding pattern by the time you are 23 years old, for example, I would doubt that finasteride or dutasteride will stop the progression completely, but it may slow down the process a bit. Do you get what I am saying?
There is no magic DHT level that you must hit as your genes do not seem to care (metaphorically speaking). You are under the illusion that DHT can be controlled, but the issue is with your genes, not DHT levels. Certainly what you are reporting appears that way.
