@kir glad to hear you're having success. Looking good, dude.
The fact remains that some are (seemingly) adversely affected by use of 5ar inhibitors like finasteride and dutasteride.
My experience on finasteride, now 15 months on 1mg daily, has fallen far far short of my hopeful wishes. Not unlike
@buckthorn, before finasteride I was a long term, gradual diffuse thinner with strong nw1 pattern. No temple recession. No vertex balding. I was only experiencing general thinning over the previous 10 years steadily. Since starting finasteride I've developed a very noticeable bald spot at the vertex on the right side, along with severe thinning of my hairline and recession of right temple by about 1 inch. The pace is brutal.
I don't know much about the up regulation theories, so I don't know if that's what I'm experiencing. I haven't experienced increased libido, itching, acne, or sebum production that seem to be part of the up regulation theory, but something fucked up is definitely going on here with regard to my finasteride use.
I keep telling myself that maybe sh*t just hit overdrive and finasteride isn't enough, but I'm too scared to jump to dutasteride and risk an even harsher response. Trapped between a rock and a hard place.
