Ethnical doesn't mean just obtaining consent, medicine is way more complicated than that.
Absolutely. Unfortunately many patients are misled by plastic Docs, some of these Drs even brag about it...they make false promises or take advantage of depression/anxiety/BDD and make bank. Any charming Dr who knows his field can manipulate things if he knows how to and has the desire, that's what is unethical and sad. Some of the hair drs are very ethnical and actually turn down more cases than accept as they have their own code of conduct and what is correct. There will be malicious and/or incompetent people in any field just the way life is.
When you see reality of hair transplants on other forums and up and close you see quite a few people have been screwed over with scars or poor growth. It actually can't be completely changed as grafts are limited and scars form on top too. Yeh, some unlucky guys are "out of the game" after 1 massive procedure which had poor growth, scars and donor overharvesting. Also own physiology plays a role, even top surgeons have failed results as some guys just can't grow the new hair well. Probably why I would never stop finasteride unless I really needed to, there is no guarantee of a good result no matter what donor you have and plus it still won't be like now.
You did well but ideally these procedures seem to be best for low NWs, top surgeon and dense packing - all about mathematics first and some artistry. Otherwise, it can be quite limited in many ways though Dr Zarev has some impressive results for people who lost a lot and they have a good illusion under most circumstances.
