In researches it is shown that Dutasteride 0.5 mg reduces scalp dht by 51% and hair follicle dht by over 90%. Which one of the two, hair follicle dht or scalp dht matters more for AGA category and the sub-category of diffuse thinning ? If one matters more, does the other matter more? Thanks, have a good evening.
That hair follicle study from Japanese scientists was this I suppose, 92% reduction of dht, basically nuking it.
Unrelated but you could find scalp reduction figures and serum reduction figures yourself over the internet, 51% and over 90% respectively (blocking both type I and type II).
There by the way exists some individuals who claim to lose hair despite hopping on dutasteride, for these reasons I decided to open up this topic.
