androgenetic alopecia
"I noticed rapid shedding of hair in March of 2015. I would occasionally count hairs lost on a day to gauge the extent of the hair loss (getting better or worse). For months I was losing well over 100 hairs a day, which was quiet concerning. For some time I deliberated whether to proceed with finasteride, as I was conscious of the negative side effects.
I started taking finasteride in August. For the next four months, my hair loss continued. It's now December, and it has completed stopped. I can run my hands through my hair/have a shower and count little to no hairs at all. My hair also feels stronger and looks thicker, which is great.
Better still, I have no noticeable negative side effects, and my sex drive is as it was previously"
