I have two photos that you may like about that, from before starting the treatment and one month after. It maybe be wishfull thinking, but I think the tiny hairs on my temples now look thicker and darker. It could also be the light, dunno...
Are you a Norwood Type II? And BTW, how long have you been on Finas?
PS: Regarding photos, try to keep a timeline of your scalp, it will help with avoiding going crazy about if it is working or not. I usually take about 5 photos: Hairline, THe two temples, middle of the head and Crown. I don't need the last one, but just to be on the safe side.
