Hi barcafan, I am a 20 year old fellow sufferer. I would just like to say I don't think you should buzz your hair, Although you have receeded the hair on top still looks very strong (I'm sure your side hair is even stronger though but just keep it short). Your hair seems still quite healthy and wavy, it reminds me of Jude Law's. I say keep it the way it is, maybe even grow the tuff out a few more inches. Could even add highlights. My point is I don't think you are at the stage of having to shave.
