I would like to see John's 7 month pics before commenting fully, but i'm very happy with my ht from Feller, at 10 months now and still got new hair maturing in the hairline.
I've had a look over some of your post history john and some photos, and you do seem to be overly fixating on your hair, I think you are your own worst critic, and it is easy to lose perspective when your staring at your noggin day after day...I don't know if you do that, but many do, and it really doesn't help. I drove myself nuts to begin with looking at my head all the time, surprised I didn't go boss eyed!
But, as others have said, 7 months repair patient, it takes longer, i've seen it time and time again, probably similar to Spex... who by the way is a life saver in the UK, hell, he should be made a saint if you saw what the clinics in the UK do to people, you'd be doing somersaults if you went to one of them!
You strike me as a worrier, paranoid, hard to switch off the brain? I can emphasise with that and your first HT, which you didn;t really need, was poor, still, a lot of cue bald guys would happily swap what you have for their NW4/5/6/7
