Thanks for the informative response. Regarding the other med I took, it wasn't equivalent to finasteride but it did warn of potential phycological side effects, like finasteride warns of possible impotence, depression, etc. Since I already know I'm susceptible to those symptoms I don't want to risk potentially years of post symptoms like I experienced in the past. I wouldn't call myself neurotic, just had a very bad experience with medication that was supposed to be "safe" but caused years of side effects so I'm very cautious not to repeat that experience. I'd also just generally prefer an natural alternative to drugs.
I'm 55 years old and have attached a pic of my crown. Seems like I don't have much more to lose. If I only have the equivalent of a couple HT treatments, couldn't I go without finasteride treatment and instead have a couple HT treatments instead? If there is little to lose, seems to me the health risk considerations and low return on investment might not justify taking the drug. I'm not good at estimating number of follicles by looking at a picture, but I can't imagine there'd be more than 3k left on the crown?
