I was planning on taking it with no guard, but the guy who buzzed it said he had the same type of thinning I did and offered to try what he does and I could just buzz it off if I didn't like it.
He buzzed the sides really short - half an inch or less and scissor-cut the top (where I have diffuse thinning all over) and left it about an inch.
At first, I was not too happy but the more people I talked to who knew about my hairloss situation, the better I felt. Everyone has said it looks really good on me. The only part I don't like is that it shows off my receding hairline a little more, but the more I look at dudes with buzzed heads, the more I think I look normal.
Short history: I've been wearing a ball cap for about a year now, all the time except when i absolutely couldn't. Prolly averaged 8 hours of cap-wearing a day. I buzzed it Tuesday morning and I've felt so good about it that I haven't put one on since then. It really has taken my mind off of it so much.
Don't get me wrong, it prolly shows that I'm losing my hair but I feel like this way, I am saying "I know and I don't care." I really feel more confident and am enjoying life a lot more now.
I've been on Propecia/nizoral for about 18 months now. I'm going to continue using it and hope for the best I know I am going to eventually lose what I have and I feel better about it now.
Good luck to everyone!
