Albion,
I have been following this thread closely as you are in the same position as me in terms of receiving a poor result.
Although I am a newbie on the forus I have received 3 HTs, the most recent was Sept 2010 (10.5 months ago) and the result is poor so I will be embarking on the dissatisfaction route just as you are...... Therefore you are not alone and there are plenty of others in the same position.
I have read your blog update and you come across as very fair, balanced in your opinions and very restrained, even though you must be incredibley disappointed.
I have studied your pics and I'm struggling to understand where the doc gets 90 per cent yield from..... Its absolutely ridiculous. Respectfully speaking (and honestly), the result is poor. All sorts of issues here with density, coverage, general appearance, subtlety, authenticity....... the list is unfortunately endless and it angers me to think that they washed their hands with you with a 10 per cent refund... shocking.
I have a personal issue with the word 'growth' too. That word is used as a 'catch all' and without stating the obvious, there are many other components to receiving a good HT.
So basically, as the refund offer is unrealistic, the most attractive option seems to be the reduced 2nd procedure...... Loads of 'buts' of course, not least of all being issues of competence and trust of the Doc. Do you still have faith in the Doctor? Bearing in mind that you have limited donor hair available you need to make sure that you are in the best possible hands the next time around: its as simple as that.
I know nothing of your personal circumstances and it is easy to do a shopping list of things here. Perhaps money may be the issue for you. I don't know.
It all depends on what your situation is before you decide on your next move, considering all the factors involved. For sure though mate, if I was you, and money is an issue for me having invested in 3 failed ops, I would DEFINITELY put my trust and confidence in the skill of the Doc before anything else.... Especially if it was my last real crack at it....
You have attracted a lot of support on this forum, people with far more knowledge and experience than I. Perhaps even people that have gone along the dissatisfaction route and can give you some real sound advice.
I hope people get on board with this one and start bringing some personal experiences and advice to the table.
All the best
