This is why I hold that finasteride is best off cycle, as you def need some DHT to run your penis and help against feminization. But on cycle, I think dustasteride with hair-friendly gear is the way to go. Switching the two may cause temporary shedding but its better than running finasteride thru a cycle and ending up with %100-%120 (or who knows how much) of your baseline DHT jizzing all over your hair follicles.
Also, do not suppress your estrogen too hard because it magnifies the effects of androgens on your hair. You wanna keep that just low enough to avoid gyno, which is harder than it sounds.
