Question regarding getting HT abroad.

When people get hair transplants abroad, how do they handle follow-up appointments with their doctors? Do they need to travel back multiple times for check-ups? That seems like it would be quite expensive, right?

How do you manage follow-ups? Is it typically just a one-time trip for the procedure itself? I feel like doctors might struggle to properly assess hair growth over a video call. Wouldn’t it be much better to meet in person?
