Should I get on fin? [pics]

[captainmoon]

I posted my pics once before, but I took some newer ones just today which I think show the extent of my hair loss a bit better. Yes, I may be in the very early stages of hair loss, but I would rather attack it early than wait until I lose more.

My hairline is concerning me more than anything. Notice how thin it is, and how uneven the hairline is (as well as the slight recession at my right temple)? It was NOT like this 6 months ago.

Let me know what you guys think. I'm thinking of going on finasteride if this worsens. I'm really willing to take the plunge despite the risk of sides. My hair is honestly one of my better features and I don't know what I would do if I lost it (as terribly vain as that sounds).
