Your hair looks really good, though it looks like you may have slight recession. Really its going to come down to what your hair loss goals are, realistically finasteride is not going to bring your hairline forward much, but it will likely help you maintain what you have.
Some people get discouraged when they hear that finasteride doesnt give that much regrowth, but honestly once your hairline recedes further you will be begging for some maintenance.
Hope I was of help. Btw I have been on finasteride for 4 months now, will the only sides being some tenderness in my testicles early on.
Havent experienced any gains, though there is no doubt it has slowed down my hairloss.
