I can deeply relate to your experience. I was scared/shunned away from finasteride by a dermatologist when I was in my early 20s, which resulted in wasting years of valuable time. Finally got on fin a few years later, now 2 years total, and like you I've mostly experienced maintenance. I was extremely bitter towards the dermatologist but over time came to accept the position I'm in. Ended up getting a hair transplant a few months ago after doing a fair bit of research, and am pretty optimistic about my future outlook.
Where did Dr. Reddy want to implant the grafts? Is the 1000 vs 2000 just a matter of density, or would he focus on more impactful areas like the front if limited to 1000 grafts?
Which areas of loss are bothering you the most?
Many people claim that implanting near weak native hair has a high risk of causing permanent shock loss, so it can be seen as higher risk than implanting on a completely bald area. You should ask the clinics about this.
Dr. Reddy did an Instagram Q&A with the forum recently which I really enjoyed, you should check it out.
There are tons of reputable surgeons in Europe. I would recommend going through a bunch of recent patient threads.
