I am noticing more thinning in the corners of my Norwood 3 where the V looking hairline is. The forelock, mid scalp, crown all look the same. But, one temple peak and the temple corners are thinning more. I know it is common to shed while starting finasteride but I have taken 1mg religiously for 2-2.5 years. What could be the culprit here? Just non responder or something else?
