it's important to point out that "inflammation" represents tenths or possibly hundreds of different molecular pathways with a similar outcome: put the cells in attack mode against an agressor and solicit intervention of aggressive white cells. While beneficial in the short-term, could accelerate aging, oxidation, and death of useful cells in the long-term.
So, DHT is probably an initiatior of inflammation, causing more than one activated pathway. In some people some pathways are more used/relevant than others to kill hair, the probable explanation why therapies work or not in a very case-by-case fashion.
"thymulin increases the anti-inflammatory activity of a specific inhibitor of the NF-κB signaling pathway, IκB kinase (IKK) inhibitor XII, in mice with acute septic inflammation"
it's possible that if thymulin blocks one pathway activated by DHT, there's still others to block. I conceive a future without finasteride when you have to use between 5 and 10 different topicals, covering all pathways, but remaining NW0 for life.
