I agree - hard to know what to believe.
I would think that it would have the same affect on DHT - systematically if taken orally, locally if applied topically.
Have any of you seen this study? It would make sense as to why I started losing my hair after increasing Zinc intake....

I am confused about Nizoral having anitandogenic properties as how is it getting to the hair follicle level to combat the DHT if it is shampoo and not a leave-on serum?
