I have been on generic 1mg finasteride for 8 months for frontal thinning. I've gotten thinner since starting fin and have a burn/stinging from the scalp where the thinning is occurring (along with back acne). Online med boards mention that fin can cause an increase in hair loss to some, including causing pain in the scalp and acne. They said it's reflex hyperandrogenicity due to Finasteride. Is that possible? How do I know if fin is causing that? I don't want to stop the medication so soon.
