Thanks for the replies!
I was talking to someone that sells Azelaic Acid and he said it blocks DHT up to 98% on hair that is not in the scalp (test tube study) and that it blocks DHT in the hair follicle up to about 20%. Anyone else hear about this? If this is true Azelaic Acid wouldn't be of much help. I tried it for a month and not only did it smell very bad but didnt see any results. May have been too soon to expect results but it was a PITA to put on every morning/night. I have a lot of hair but want to keep what I have.
I also tried liquid spiro which btw smells pretty bad and a few people on this forum mentioned that taking spiro is suppressive and non-anabolic even in topical form
So far I have not found any real hair loss prevention that works? I have been using 2% Nizoral, Saw Palmetto caps, spiro and liquid fina (caused loss in libido and erections) with no success. Might try Minoxidil Topical / Azelaic Acid 5% DHT Inhibitor or just normal Rogain (Minoxidil) to see what happens. From what I have read Minoxidil will create new hair but once you stop using it the new hair falls out.
