Haven't check the forums in a while. Well Finasteride was only providing approx 70% type 2 reduction, yes this is essentially the only kind that matters as it is synthesized in the dermal pappila and acts as an autocrine hormone. Dutasteride is 3x as potent at inhibiting type 2 so usually the larger reduction is from type 2. I remember reading that finasteride at its best reduces type 2 by about 85-90%, however it you can fall anyhwere between 60-90% on that curve. Dutasteride inhibits 98-99% of type in in just about everyone. In my opinion this is why its so effective. Been about 7 months now and im still counting 0 hairs in the sink and shower. Its crazy how unnaturally good this drug is for some at stopping hairloss.
